He compared the shape of the human eye to the lens in his camera obscura, and provided an easily understandable example of how light could bring images into the eye. Della Porta also claimed to have invented the first telescope , but died while preparing the treatise ( De telescopiis ) in support of his claim. His efforts were also overshadowed by Galileo Galilei 's improvement of
624-694: A worldwide famous cuisine . Due to comparatively late national unification, and the historical autonomy of the regions that comprise the Italian peninsula, many traditions and customs of the Italians can be identified by their regions of origin.

10140-962: The air". Early attempts at predicting weather were often related to prophecy and divining , and were sometimes based on astrological ideas. Ancient religions believed meteorological phenomena to be under the control of the gods. The ability to predict rains and floods based on annual cycles was evidently used by humans at least from the time of agricultural settlement if not earlier. Early approaches to predicting weather were based on astrology and were practiced by priests. The Egyptians had rain-making rituals as early as 3500 BC. Ancient Indian Upanishads contain mentions of clouds and seasons . The Samaveda mentions sacrifices to be performed when certain phenomena were noticed. Varāhamihira 's classical work Brihatsamhita , written about 500 AD, provides evidence of weather observation. Cuneiform inscriptions on Babylonian tablets included associations between thunder and rain. The Chaldeans differentiated

He discussed terrestrial bodies and vapors which arise from them, proceeding to explain the formation of clouds from drops of water, and winds, clouds then dissolving into rain, hail and snow. He also discussed the effects of light on the rainbow. Descartes hypothesized that all bodies were composed of small particles of different shapes and interwovenness. All of his theories were based on this hypothesis. He explained

In 1761, Joseph Black discovered that ice absorbs heat without changing its temperature when melting. In 1772, Black's student Daniel Rutherford discovered nitrogen , which he called phlogisticated air , and together they developed
11388-511: The best example of this type is Morfeo in the comedy La Fantesca . Italians Italians ( Italian : italiani , pronounced [itaˈljaːni] ) are an ethnic group native to the Italian geographical region . Italians share a common culture , history , ancestry and language . Their predecessors differ regionally, but generally include native populations such as the Etruscans ,
11544-460: The best known products of meteorologists for the public, weather presenters on radio and television are not necessarily professional meteorologists. They are most often reporters with little formal meteorological training, using unregulated titles such as weather specialist or weatherman . The American Meteorological Society and National Weather Association issue "Seals of Approval" to weather broadcasters who meet certain requirements but this
11700-401: The calculations led to unrealistic results. Though numerical analysis later found that this was due to numerical instability . Starting in the 1950s, numerical forecasts with computers became feasible. The first weather forecasts derived this way used barotropic (single-vertical-level) models, and could successfully predict the large-scale movement of midlatitude Rossby waves , that is,
11856-587: The capital of the kingdom. Pope Pius IX , a longtime rival of Italian kings, stated he had been made a "prisoner" inside the Vatican walls and refused to cooperate with the royal administration. Only in 1929 did the Roman Pope accept the unified Italy with Rome as capital. World War I has been interpreted as completing the process of Italian unification, with the annexation of Trieste, Istria , Trentino-Alto Adige and Zara . After World War I, Italy emerged as one of
12012-492: The chaotic nature of the atmosphere. Mathematical models used to predict the long term weather of the Earth ( climate models ), have been developed that have a resolution today that are as coarse as the older weather prediction models. These climate models are used to investigate long-term climate shifts, such as what effects might be caused by human emission of greenhouse gases . Meteorologists are scientists who study and work in
12168-496: The characters of the commedia erudita are uniquely created by the text in which they appear, unlike the masks, which remain constant from one scenario to another. Indeed, the masks of the improvised theatre evolved as stylised versions of recurring character types in written comedies. One of Della Porta's most notable stock characters was the parasito or parassita , a gluttonous trickster whose lack of moral scruples enabled him to pull off stunts that initially might risk bringing
12324-413: The church and princes. This was supported by scientists like Johannes Muller , Leonard Digges , and Johannes Kepler . However, there were skeptics. In the 14th century, Nicole Oresme believed that weather forecasting was possible, but that the rules for it were unknown at the time. Astrological influence in meteorology persisted until the eighteenth century. Gerolamo Cardano 's De Subilitate (1550)
12480-689: The city was far from the troubled frontiers. The seats of the Caesars became Augusta Treverorum (on the River Rhine frontier) for Constantius Chlorus and Sirmium (on the River Danube frontier) for Galerius , who also resided at Thessaloniki . Under Diocletian, Italy became the Dioecesis Italiciana , subdivided into thirteen provinces, now including Raetia . Under Constantine the Great , Italy became
12636-568: The climate with public health. During the Age of Enlightenment meteorology tried to rationalise traditional weather lore, including astrological meteorology. But there were also attempts to establish a theoretical understanding of weather phenomena. Edmond Halley and George Hadley tried to explain trade winds . They reasoned that the rising mass of heated equator air is replaced by an inflow of cooler air from high latitudes. A flow of warm air at high altitude from equator to poles in turn established an early picture of circulation. Frustration with
12792-422: The clouds and winds extended up to 111 miles, but Posidonius thought that they reached up to five miles, after which the air is clear, liquid and luminous. He closely followed Aristotle's theories. By the end of the second century BC, the center of science shifted from Athens to Alexandria , home to the ancient Library of Alexandria . In the 2nd century AD, Ptolemy 's Almagest dealt with meteorology, because it
12948-491: The description of what is now known as the hydrologic cycle . His work would remain an authority on meteorology for nearly 2,000 years. The book De Mundo (composed before 250 BC or between 350 and 200 BC) noted: After Aristotle, progress in meteorology stalled for a long time. Theophrastus compiled a book on weather forecasting, called the Book of Signs , as well as On Winds . He gave hundreds of signs for weather phenomena for
13104-626: The early study of weather systems. Nineteenth century researchers in meteorology were drawn from military or medical backgrounds, rather than trained as dedicated scientists. In 1854, the United Kingdom government appointed Robert FitzRoy to the new office of Meteorological Statist to the Board of Trade with the task of gathering weather observations at sea. FitzRoy's office became the United Kingdom Meteorological Office in 1854,
13260-544: The efforts of noblemen, emperors, and larger foreign powers to control them. The emergence of identifiable Italian dialects from Vulgar Latin , and as such the possibility of a specifically "Italian" ethnic identity, has no clear-cut date, but began in roughly the 12th century. Modern standard Italian derives from the written vernacular of Tuscan writers of the 12th century. The recognition of Italian vernaculars as literary languages in their own right began with De vulgari eloquentia , an essay written by Dante Alighieri at
13416-483: The eggshell which is semi-porous. When the eggshell was dry, he boiled the egg in hot water and the ink on the outside of the egg was washed away. When the recipient in prison peeled off the shell, the message was revealed once again on the egg white. De Furtivis Literarum Notis also contains one of the earliest known examples of music substitution ciphers . In 1586 della Porta published a work on physiognomy , De humana physiognomonia libri IIII (1586). This influenced
13572-491: The empire against the ascendant city republics in the 13th century. The Italian peninsula was divided into a multitude of tribal or ethnic territory prior to the Roman conquest of Italy in the 3rd century BC. After a series of wars between Greeks and Etruscans , the Latins , with Rome as their capital, gained the ascendancy by 272 BC, and completed the conquest of the Italian peninsula by 218 BC. This period of unification
13728-514: The etymology of the Latin name "Italia" are numerous. One is that it was borrowed via Greek from the Oscan Víteliú 'land of calves' ( cf. Lat vitulus "calf", Umb vitlo "calf"). Greek historian Dionysius of Halicarnassus states this account together with the legend that Italy was named after Italus , mentioned also by Aristotle and Thucydides . According to Antiochus of Syracuse ,
13884-482: The existence of a circulation cell in the mid-latitudes, and the air within deflected by the Coriolis force resulting in the prevailing westerly winds. Late in the 19th century, the motion of air masses along isobars was understood to be the result of the large-scale interaction of the pressure gradient force and the deflecting force. By 1912, this deflecting force was named the Coriolis effect. Just after World War I,
14040-460: The existence of which predates the national language. Although there is disagreement on the total number, according to UNESCO , there are approximately 30 languages native to Italy , although many are often misleadingly referred to as "Italian dialects ". Since 2017, in addition to the approximately 55 million Italians in Italy (91% of the Italian national population), Italian-speaking autonomous groups are found in neighboring nations; about
14196-682: The expansion of the Roman Republic , the name was used by Greeks to indicate the land between the Strait of Messina and the line connecting the Gulf of Salerno and Gulf of Taranto , corresponding roughly to the current region of Calabria . The Greeks gradually came to apply the name "Italia" to a larger region In addition to the "Greek Italy" in the south, historians have suggested the existence of an "Etruscan Italy" covering variable areas of central Italy. The borders of Roman Italy are better established. Cato
14352-467: The explanation that the cause of the Nile 's annual floods was due to northerly winds hindering its descent by the sea. Anaximander and Anaximenes thought that thunder and lightning was caused by air smashing against the cloud, thus kindling the flame. Early meteorological theories generally considered that there was a fire-like substance in the atmosphere. Anaximander defined wind as a flowing of air, but this
14508-443: The field of meteorology. The American Meteorological Society publishes and continually updates an authoritative electronic Meteorology Glossary . Meteorologists work in government agencies , private consulting and research services, industrial enterprises, utilities, radio and television stations , and in education . In the United States, meteorologists held about 10,000 jobs in 2018. Although weather forecasts and warnings are
14664-447: The final victor (31 BC), was accorded the title of Augustus by the Senate and thereby became the first Roman Emperor. Augustus created for the first time an administrative region called Italia with inhabitants called "Italicus populus", stretching from the Alps to Sicily : for this reason historians like Emilio Gentile called him Father of Italians . In the 1st century BC, Italia
14820-652: The first weather observing network, that consisted of meteorological stations in Florence , Cutigliano , Vallombrosa , Bologna , Parma , Milan , Innsbruck , Osnabrück , Paris and Warsaw . The collected data were sent to Florence at regular time intervals. In the 1660s Robert Hooke of the Royal Society of London sponsored networks of weather observers. Hippocrates ' treatise Airs, Waters, and Places had linked weather to disease. Thus early meteorologists attempted to correlate weather patterns with epidemic outbreaks, and
14976-575: The first observation of fungal spores is recorded, making him a pioneer of mycology . His private museum was visited by travellers and was one of the earliest examples of natural history museums. It inspired the Jesuit Athanasius Kircher to begin a similar, even more renowned, collection in Rome. Della Porta was the founder of a scientific society called the Academia Secretorum Naturae (Accademia dei Segreti). This group
15132-523: The first person to attack in print, on experimental grounds, the ancient assertion that garlic could disempower magnets. This was an early example of the authority of early authors being replaced by experiment as the backing for a scientific assertion. Della Porta's conclusion was confirmed experimentally by Thomas Browne , among others. In later life, della Porta collected rare specimens and grew exotic plants. His work Phytognomonica lists plants according to their geographical location. In Phytognomonica
15288-455: The first public performance of the song Il Canto degli Italiani , the Italian national anthem since 1946, took place. Il Canto degli Italiani , written by Goffredo Mameli set to music by Michele Novaro , is also known as the Inno di Mameli , after the author of the lyrics, or Fratelli d'Italia , from its opening line . The unification of Italy was brought to a successful conclusion under
15444-400: The first time, a practical method for quickly gathering surface weather observations from a wide area. This data could be used to produce maps of the state of the atmosphere for a region near the Earth's surface and to study how these states evolved through time. To make frequent weather forecasts based on these data required a reliable network of observations, but it was not until 1849 that
15600-407: The first to give the correct explanations for the primary rainbow phenomenon. Theoderic went further and also explained the secondary rainbow. By the middle of the sixteenth century, meteorology had developed along two lines: theoretical science based on Meteorologica , and astrological weather forecasting. The pseudoscientific prediction by natural signs became popular and enjoyed protection of
15756-633: The first weather forecasts and temperature predictions. In the 20th and 21st centuries, with the advent of computer models and big data, meteorology has become increasingly dependent on numerical methods and computer simulations. This has greatly improved weather forecasting and climate predictions. Additionally, meteorology has expanded to include other areas such as air quality, atmospheric chemistry, and climatology. The advancement in observational, theoretical and computational technologies has enabled ever more accurate weather predictions and understanding of weather pattern and air pollution. In current time, with
15912-405: The following: agriculture , hydraulics , Military Engineering , instruments , and pharmacology . He published a book in 1606 on raising water by the force of the air. In 1608 he published a book on military engineering, and another on distillation . Additionally, della Porta perfected the camera obscura . In a later edition of his Natural Magic , della Porta described this device as having
16068-582: The forerunner of the Japan Meteorological Agency , began constructing surface weather maps in 1883. The United States Weather Bureau (1890) was established under the United States Department of Agriculture . The Australian Bureau of Meteorology (1906) was established by a Meteorology Act to unify existing state meteorological services. In 1904, Norwegian scientist Vilhelm Bjerknes first argued in his paper Weather Forecasting as
16224-516: The form of wind. He explained thunder by saying that it was due to ice colliding in clouds, and in Summer it melted. In the thirteenth century, Aristotelian theories reestablished dominance in meteorology. For the next four centuries, meteorological work by and large was mostly commentary . It has been estimated over 156 commentaries on the Meteorologica were written before 1650. Experimental evidence
16380-519: The guidance of Camillo Benso, conte di Cavour , prime minister of Piedmont. Cavour managed to unite most of Italy under the headship of Victor Emmanuel II of the house of Savoy, and on 17 March 1861, the Kingdom of Italy was proclaimed with Victor Emmanuel II as king. Giuseppe Garibaldi , the popular republican hero of Italy, contributed much to this achievement with the Expedition of the Thousand and to
16536-505: The house resembled an academy for his sons. The members of the learned circle of friends stimulated the boys, tutoring and mentoring them, under the strict guidance of their father. In addition to having talents for the sciences and mathematics, all the brothers were also extremely interested in the arts, music in particular. Despite their interest, none of them possessed any sort of talent for it, but they did not allow that to stifle their progress in learning theory. They were all accepted into
16692-505: The island of Sardinia, which had been ceded to the Alpine House of Savoy in 1720 and had remained under their rule ever since, were not under French control. French domination lasted less than 20 years, and it differed from previous foreign control of the Italian peninsula. In spite of heavy taxation and frequent harshness, the French introduced representative assemblies and new laws that were
16848-413: The lack of discipline among weather observers, and the poor quality of the instruments, led the early modern nation states to organise large observation networks. Thus, by the end of the 18th century, meteorologists had access to large quantities of reliable weather data. In 1832, an electromagnetic telegraph was created by Baron Schilling . The arrival of the electrical telegraph in 1837 afforded, for
17004-500: The lakes and the Nile. Hippocrates inquired into the effect of weather on health. Eudoxus claimed that bad weather followed four-year periods, according to Pliny. These early observations would form the basis for Aristotle 's Meteorology , written in 350 BC. Aristotle is considered the founder of meteorology. One of the most impressive achievements described in the Meteorology is
17160-609: The largest Italian community outside Italy), more than 18 million Italian Americans , and people in other parts of Europe (e.g. Italians in Germany , Italians in France and Italians in the United Kingdom ), the American Continent (such as Italian Venezuelans , Italian Canadians , Italian Colombians and Italians in Paraguay , among others), Australasia ( Italian Australians and Italian New Zealanders ), and to
17316-437: The late 16th century and first half of the 17th century a range of meteorological instruments were invented – the thermometer , barometer , hydrometer , as well as wind and rain gauges. In the 1650s natural philosophers started using these instruments to systematically record weather observations. Scientific academies established weather diaries and organised observational networks. In 1654, Ferdinando II de Medici established
17472-407: The lesser-known tradition of the commedia erudita rather than the commedia dell'arte - which means they were written out as entire scripts instead of being improvised from a scenario - della Porta's comedies are eminently performable. While there are obvious similarities between some of the characters in della Porta's comedies and the masks of the commedia dell'arte, it should be borne in mind that
17628-443: The mechanical, self-emptying, tipping bucket rain gauge. In 1714, Gabriel Fahrenheit created a reliable scale for measuring temperature with a mercury-type thermometer . In 1742, Anders Celsius , a Swedish astronomer, proposed the "centigrade" temperature scale, the predecessor of the current Celsius scale. In 1783, the first hair hygrometer was demonstrated by Horace-Bénédict de Saussure . In 1802–1803, Luke Howard wrote On
17784-448: The mid-15th century and were respectively the rain gauge , the anemometer, and the hygrometer. Many attempts had been made prior to the 15th century to construct adequate equipment to measure the many atmospheric variables. Many were faulty in some way or were simply not reliable. Even Aristotle noted this in some of his work as the difficulty to measure the air. Sets of surface measurements are important data to meteorologists. They give
17940-448: The most popular in the world, its cinema (with filmmakers such as Federico Fellini , Michelangelo Antonioni , Mario Monicelli , Sergio Leone , etc.), its collections of priceless works of art and its fashion (Milan and Florence are regarded as some of the few fashion capitals of the world). National symbols of Italy are the symbols that uniquely identify Italy reflecting its history and culture . They are used to represent
18096-506: The needles such that when a letter was dialled in one box, the needle in the other box would swing to point to the same letter, thereby helping in communicating. A Catholic , della Porta was examined by the Inquisition in the years prior to 1578. He was forced to disband his Academia Secretorum Naturae , and in 1592 his philosophical works were prohibited from further publication by the Church;
18252-549: The night, with change being likely at one of these divisions. Applying the divisions and a principle of balance in the yearly weather, he came up with forecasts like that if a lot of rain falls in the winter, the spring is usually dry. Rules based on actions of animals are also present in his work, like that if a dog rolls on the ground, it is a sign of a storm. Shooting stars and the Moon were also considered significant. However, he made no attempt to explain these phenomena, referring only to
18408-507: The opposite effect. Rene Descartes 's Discourse on the Method (1637) typifies the beginning of the scientific revolution in meteorology. His scientific method had four principles: to never accept anything unless one clearly knew it to be true; to divide every difficult problem into small problems to tackle; to proceed from the simple to the complex, always seeking relationships; to be as complete and thorough as possible with no prejudice. In
18564-407: The outlines of a new Italy began to appear. Victor Emmanuel III gave up the throne on 9 May 1946, and his son, Umberto II , became king. On 2 June Italy held its first free election after 20 years of Fascist rule (the so-called Ventennio ). Italians chose a republic to replace the monarchy , which had been closely associated with Fascism . They elected a Constituent Assembly , which was formed by
18720-516: The pattern of atmospheric lows and highs . In 1959, the UK Meteorological Office received its first computer, a Ferranti Mercury . In the 1960s, the chaotic nature of the atmosphere was first observed and mathematically described by Edward Lorenz , founding the field of chaos theory . These advances have led to the current use of ensemble forecasting in most major forecasting centers, to take into account uncertainty arising from
18876-407: The plot crashing down, but ended up winning the day in unexpected ways. The term parasito was translated by John Florio in his Italian to English Dictionary first published in 1598 as a smell-feast, a flatterer, a parasite, a trencherd or bellie friend, one that saieth and doeth all things to please the humor of another, and agreeth unto him in all things to have his repast scotfree . Perhaps
19032-415: The prognostic fluid dynamics equations that govern atmospheric flow could be neglected, and a numerical calculation scheme that could be devised to allow predictions. Richardson envisioned a large auditorium of thousands of people performing the calculations. However, the sheer number of calculations required was too large to complete without electronic computers, and the size of the grid and time steps used in
19188-521: The rain as caused by clouds becoming too large for the air to hold, and that clouds became snow if the air was not warm enough to melt them, or hail if they met colder wind. Like his predecessors, Descartes's method was deductive, as meteorological instruments were not developed and extensively used yet. He introduced the Cartesian coordinate system to meteorology and stressed the importance of mathematics in natural science. His work established meteorology as
19344-545: The region. Venice, Milan, and other city-states retained at least some of their former greatness during this period, as did Savoy -Piedmont, protected by the Alps and well defended by its vigorous rulers. Italian explorers and navigators from the dominant maritime republics, eager to find an alternative route to the Indies in order to bypass the Ottoman Empire , offered their services to monarchs of Atlantic countries and played
19500-637: The representatives of all the anti-fascist forces that contributed to the defeat of Nazi and Fascist forces during the Italian Civil War , to prepare a new democratic constitution. The Assembly approved the new Italian constitution in 1947, which came into force on 1 January 1948. Under the Treaty of Peace with Italy, 1947 , Istria , Kvarner , most of the Julian March as well as the Dalmatian city of Zara
19656-537: The same for all parts of the country. For the first time since the days of ancient Rome, Italians of different regions used the same money and served in the same army. Many Italians began to see the possibility of a united Italy free of foreign control. During the Napoleonic era , in 1797, the first official adoption of the Italian tricolour as a national flag by a sovereign Italian state, the Cispadane Republic ,
19812-475: The science of meteorology. Meteorological phenomena are described and quantified by the variables of Earth's atmosphere: temperature, air pressure, water vapour , mass flow , and the variations and interactions of these variables, and how they change over time. Different spatial scales are used to describe and predict weather on local, regional, and global levels. Meteorology, climatology , atmospheric physics , and atmospheric chemistry are sub-disciplines of
19968-442: The scientific revolution in meteorology. Speculation on the cause of the flooding of the Nile ended when Eratosthenes , according to Proclus , stated that it was known that man had gone to the sources of the Nile and observed the rains, although interest in its implications continued. During the era of Roman Greece and Europe, scientific interest in meteorology waned. In the 1st century BC, most natural philosophers claimed that
20124-440: The seasons. He believed that fire and water opposed each other in the atmosphere, and when fire gained the upper hand, the result was summer, and when water did, it was winter. Democritus also wrote about the flooding of the Nile. He said that during the summer solstice, snow in northern parts of the world melted. This would cause vapors to form clouds, which would cause storms when driven to the Nile by northerly winds, thus filling
20280-578: The second oldest national meteorological service in the world (the Central Institution for Meteorology and Geodynamics (ZAMG) in Austria was founded in 1851 and is the oldest weather service in the world). The first daily weather forecasts made by FitzRoy's Office were published in The Times newspaper in 1860. The following year a system was introduced of hoisting storm warning cones at principal ports when
20436-492: The service of France, renowned as the first European to explore the Atlantic coast of North America between Florida and New Brunswick in 1524. The French Revolution and Napoleon influenced Italy more deeply than they affected any other outside country of Europe. The French Revolution began in 1789 and immediately found supporters among the Italian people. The local Italian rulers, sensing danger in their own country, drew closer to
20592-465: The subject, but among those whose work can be studied he towers like a giant. Della Porta invented a method which allowed him to write secret messages on the inside of eggs. Some of his friends were imprisoned by the Inquisition. At the gate of the prison, everything was checked except for eggs. Della Porta wrote messages on the eggshell using a mixture made of plant pigments and alum . The ink penetrated
20748-787: The subsequent incorporation of the Papal States under the Italian monarch. Cavour handed Savoy and Nice over to France at the Treaty of Turin , a decision that was the consequence of the Plombières Agreement , on 24 March 1860, an event that caused the Niçard exodus , which was the emigration of a quarter of the Niçard Italians to Italy, and the Niçard Vespers . Italian troops occupied Rome in 1870, and in July 1871, this formally became
20904-427: The telegraph and photography led to the creation of weather observing networks and the ability to track storms. Additionally, scientists began to use mathematical models to make predictions about the weather. The 20th century saw the development of radar and satellite technology, which greatly improved the ability to observe and track weather systems. In addition, meteorologists and atmospheric scientists started to create
21060-518: The telescope in 1609, following its introduction by Lippershey in the Netherlands in 1608. In the book, della Porta also mentioned an imaginary device known as a sympathetic telegraph . The device consisted of two circular boxes, similar to compasses, each with a magnetic needle, supposed to be magnetized by the same lodestone . Each box was to be labelled with the 26 letters, instead of the usual directions. Della Porta assumed that this would coordinate
21216-539: The term Italy was used by the Greeks to initially refer only to the southern portion of the Bruttium peninsula corresponding to the modern province of Reggio and part of the provinces of Catanzaro and Vibo Valentia in Southern Italy . Nevertheless, by his time the larger concept of Oenotria and "Italy" had become synonymous and the name also applied to most of Lucania as well. According to Strabo 's Geographica , before
21372-572: The value of his work is in preserving earlier speculation, much like Seneca's work. From 400 to 1100, scientific learning in Europe was preserved by the clergy. Isidore of Seville devoted a considerable attention to meteorology in Etymologiae , De ordine creaturum and De natura rerum . Bede the Venerable was the first Englishman to write about the weather in De Natura Rerum in 703. The work
21528-433: The whole Italian geographical region . All its inhabitants were considered Italic and Roman . The Latin term Italicus was used to describe "a man of Italy" as opposed to a provincial . For example, Pliny the Elder notably wrote in a letter Italicus es an provincialis ? meaning "are you an Italian or a provincial?". The adjective italianus , from which are derived the Italian (and also French and English) name of
21684-417: Was a summary of then extant classical sources. However, Aristotle's works were largely lost until the twelfth century, including Meteorologica . Isidore and Bede were scientifically minded, but they adhered to the letter of Scripture . Islamic civilization translated many ancient works into Arabic which were transmitted and translated in western Europe to Latin. In the 9th century, Al-Dinawari wrote
21840-566: Was adopted by the Lombard Legion in 1796. The first red, white and green national flag of a sovereign Italian state was adopted on 7 January 1797, when the Fourteenth Parliament of the Cispadane Republic (1797), on the proposal of deputy Giuseppe Compagnoni , decreed "to make universal the ... standard or flag of three colours, green, white, and red ...": For having proposed the green, white and red tricolour flag, Giuseppe Compagnoni
21996-466: Was annexed by Yugoslavia causing the Istrian-Dalmatian exodus , which led to the emigration of between 230,000 and 350,000 of local ethnic Italians ( Istrian Italians and Dalmatian Italians ), the others being ethnic Slovenians, ethnic Croatians, and ethnic Istro-Romanians , choosing to maintain Italian citizenship . In 1949 Italy became a member of NATO . The Marshall Plan helped to revive
22152-468: Was considered a subset of astronomy. He gave several astrological weather predictions. He constructed a map of the world divided into climatic zones by their illumination, in which the length of the Summer solstice increased by half an hour per zone between the equator and the Arctic. Ptolemy wrote on the atmospheric refraction of light in the context of astronomical observations. In 25 AD, Pomponius Mela ,
22308-465: Was deposed in 476 by a Germanic foederati general in Italy, Odoacer . His defeat marked the end of the Western Roman Empire , and the end of the political unification of Italy until the establishment of the modern Kingdom of Italy in 1861. Odoacer ruled well for 13 years after gaining control of Italy in 476. Then he was attacked and defeated by Theodoric , the king of another Germanic tribe,
22464-616: Was followed by one of conquest in the Mediterranean, beginning with the First Punic War against Carthage . In the course of the century-long struggle against Carthage, the Romans conquered Sicily, Sardinia and Corsica. Finally, in 146 BC, at the conclusion of the Third Punic War , with Carthage completely destroyed and its inhabitants enslaved, Rome became the dominant power in the Mediterranean. The process of Italian unification, and
22620-478: Was legally merged into the administrative unit of Italy in 42 BC by the triumvir Octavian as a ratification of Julius Caesar 's unpublished acts ( Acta Caesaris ). Under Emperor Diocletian the Roman region called "Italia" was further enlarged with the addition in 292 AD of the three big islands of the western Mediterranean Sea : Sicily (with the Maltese archipelago ), Sardinia and Corsica , coinciding with
22776-428: Was less important than appeal to the classics and authority in medieval thought. In the thirteenth century, Roger Bacon advocated experimentation and the mathematical approach. In his Opus majus , he followed Aristotle's theory on the atmosphere being composed of water, air, and fire, supplemented by optics and geometric proofs. He noted that Ptolemy's climatic zones had to be adjusted for topography . St. Albert
22932-521: Was more commonly known as the Otiosi , (Men of Leisure). Founded sometime before 1580, the Otiosi were one of the first scientific societies in Europe and their aim was to study the "secrets of nature." Any person applying for membership had to demonstrate they had made a new discovery in the natural sciences . The Academia Secretorum Naturae was compelled to disband when its members were suspected of dealing with
23088-406: Was not generally accepted for centuries. A theory to explain summer hail was first proposed by Anaxagoras . He observed that air temperature decreased with increasing height and that clouds contain moisture. He also noted that heat caused objects to rise, and therefore the heat on a summer day would drive clouds to an altitude where the moisture would freeze. Empedocles theorized on the change of
23244-589: Was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century, the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water. Meteorological phenomena are observable weather events that are explained by

In 1743, when Benjamin Franklin was prevented from seeing a lunar eclipse by a hurricane , he decided that cyclones move in a contrary manner to the winds at their periphery. Understanding the kinematics of how exactly the rotation of the Earth affects airflow was partial at first. Gaspard-Gustave Coriolis published a paper in 1835 on the energy yield of machines with rotating parts, such as waterwheels. In 1856, William Ferrel proposed
