Extratropical cyclones , sometimes called mid-latitude cyclones or wave cyclones , are low-pressure areas which, along with the anticyclones of high-pressure areas , drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe hail , thunderstorms , blizzards , and tornadoes . These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones , extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts , about the center of the cyclone.
111-547: Pescara ( Italian: [pesˈkaːra] ; Abruzzese : Pescàrë ; Pescarese : Piscàrë ) is the capital city of the province of Pescara , in the Abruzzo region of Italy . It is the most populated city in Abruzzo, with 118,657 (January 1, 2023) residents (and approximately 350,000 including the surrounding metropolitan area). Located on the Adriatic coast at the mouth of
222-515: A in Napoli Naples ieri. Extratropical cyclone The term " cyclone " applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if
333-753: A ; masc. "long", fem. "long"), whereas in Italian it is expressed by a change in the final vowel. These and other morpho-syntactic differences distinguish the Neapolitan language from the Italian language and the Neapolitan accent. Neapolitan has had a significant influence on the intonation of Rioplatense Spanish spoken in Buenos Aires and the surrounding region of Argentina and in the entire country of Uruguay . While there are only five graphic vowels in Neapolitan, phonemically, there are eight. Stressed vowels e and o can be either " closed " or " open " and
444-462: A category 5 hurricane . In the Arctic , the average pressure for cyclones is 980 millibars (28.94 inHg) during the winter, and 1,000 millibars (29.53 inHg) during the summer. Tropical cyclones often transform into extratropical cyclones at the end of their tropical existence, usually between 30° and 40° latitude, where there is sufficient forcing from upper-level troughs or shortwaves riding
555-412: A humid subtropical climate (Cfa) with Mediterranean influences. The city's climate is characterized by hot summers and cool winters. Since its driest month has 34 mm (1.3 inches) of precipitation, the city cannot be solely classified as Mediterranean. Not to mention, although there is a dry tendency in early summer, August (late summer) is as wet as the winter month of February, which is unusual for

To the south the pine forest that once gave shade to bathers along much of the Adriatic coast, has almost disappeared near the beach, but remains within the Nature Reserve Pineta Dannunziana . The urban fabric of the city spreads over a flat T-shaped area, which occupies the valley around the river and the coastal strip. To the northwest and the southwest,
888-471: A connection with the airline's hub. Pescara is served by the Port of Pescara for fishing, yachting, cargo docking and commercial passenger services. In summer season ferries and hydrofoils to Croatia run primarily by SNAV to Split and islands in central Dalmatia , but often they set out from the larger and better equipped Port of Ortona. The city has four railway stations , Pescara Centrale railway station

The trowal creates the portion of an occluded cyclone known as its comma head , due to
1110-406: A definitive lower to mid-level warm core structure. A warm seclusion, the result of a baroclinic lifecycle, occurs at latitudes well poleward of the tropics. As latent heat flux releases are important for their development and intensification, most warm seclusion events occur over the oceans ; they may impact coastal nations with hurricane force winds and torrential rain . Climatologically,
1221-415: A favorable quadrant of a maximum in the upper level jetstream known as a jet streak. The favorable quadrants are usually at the right rear and left front quadrants, where divergence ensues. The divergence causes air to rush out from the top of the air column. As mass in the column is reduced, atmospheric pressure at surface level (the weight of the air column) is reduced. The lowered pressure strengthens

It was developed completely from surface-based weather observations, including descriptions of clouds found near frontal boundaries. This theory still retains merit, as it is a good description for extratropical cyclones over continental landmasses. A second competing theory for extratropical cyclone development over

Although most tropical cyclones that become extratropical quickly dissipate or are absorbed by another weather system, they can still retain winds of hurricane or gale force. In 1954, Hurricane Hazel became extratropical over North Carolina as
1554-472: A mere difference in Italian pronunciation. Therefore, while pronunciation presents the strongest barrier to comprehension, the grammar of Neapolitan is what sets it apart from Italian. In Neapolitan, for example, the gender and number of a word is expressed by a change in the accented vowel because it no longer distinguishes final unstressed / a / , / e / and / o / (e.g. l uo ngo [ˈlwoŋɡə] , l o nga [ˈloŋɡə] ; Italian lung o , lung

The most intense extratropical cyclone across the North Pacific Ocean occurred in November 2014, when a cyclone partially related to Typhoon Nuri reached a record low pressure of 920 mbar (27 inHg). In October 2021, the most intense Pacific Northwest windstorm occurred off
1887-597: A separate municipality. In 1814, Pescara's Carboneria revolted against Joachim Murat . There, on 15 May 1815, the king undersigned one of the first constitutions of the Italian Risorgimento . In the following years Pescara became a symbol of the Bourbon 's violent restoration as it housed one of the most notorious Bourbon jails. After a devastating flood in 1853, Pescara was liberated by Giuseppe Garibaldi 's collaborator Clemente De Caesaris in 1860. Seven years later
1998-737: A small frazione of the fortress. In 1707 it was attacked by Austrian troops under the command of the Count of Wallis : the town, led by Giovanni Girolamo II Acquaviva , resisted for two months before capitulating. Pescara was always part of the Kingdom of Naples , apart from the brief age of the Republic of Naples of 1798–99. The town was therefore attacked by the pro- Bourbon Giuseppe Pronio . In 1800 Pescara fell to French troops, becoming an important military stronghold of Joseph Bonaparte 's reign. Castellammare, which now had 3,000 inhabitants of its own, became

On the northern waterfront, close to the Salotto Square , the main square of the city, there is the Nave (trad. the ship), a sculpture by Pietro Cascella . Pescara is the most populous city in the Abruzzo region, and
2220-522: A strong Category 3 storm. The Columbus Day Storm of 1962 , which evolved from the remains of Typhoon Freda, caused heavy damage in Oregon and Washington , with widespread damage equivalent to at least a Category 3. In 2005, Hurricane Wilma began to lose tropical characteristics while still sporting Category 3-force winds (and became fully extratropical as a Category 1 storm). In summer, extratropical cyclones are generally weak, but some of
2331-527: A strong baroclinic system and achieved warm seclusion status at maturity (or lowest pressure). Extratropical cyclones are generally driven, or "steered", by deep westerly winds in a general west to east motion across both the Northern and Southern hemispheres of the Earth. This general motion of atmospheric flow is known as "zonal". Where this general trend is the main steering influence of an extratropical cyclone, it

#17328375685082442-513: A tropical cyclone has intruded into the mid latitudes. Weather forecasters and the general public often describe them simply as " depressions " or "lows". Terms like frontal cyclone, frontal depression, frontal low, extratropical low, non-tropical low and hybrid low are often used as well. Extratropical cyclones are classified mainly as baroclinic , because they form along zones of temperature and dewpoint gradient known as frontal zones . They can become barotropic late in their life cycle, when
2553-464: A tropical cyclone. The Joint Typhoon Warning Center uses the extratropical transition (XT) technique to subjectively estimate the intensity of tropical cyclones becoming extratropical based on visible and infrared satellite imagery . Loss of central convection in transitioning tropical cyclones can cause the Dvorak technique to fail; the loss of convection results in unrealistically low estimates using
2664-628: A very modern coastal city of Italy. The city is divided in two by the river in between. The historic city center is located on the south shore, where once stood the Piazzaforte (fortified town), a military bulwark of the Kingdom of the Two Sicilies . There is the Bagno Borbonico (the old prison of the Kingdom of the Two Sicilies, built starting in 1510 by order of Charles V , which incorporated inside

Before a word beginning with a vowel, l’ or ll’ are used for both masculine and feminine, singular and plural. Although both forms can be found, the ll’ form is by far the most common. In Neapolitan,
2886-540: A word or between two vowels: e.g. doje (feminine) or duje (masculine), meaning "two", is pronounced, and often spelled, as roje / ruje ; vedé ("to see") as veré , and often spelled so; also cadé / caré ("to fall") and Madonna / Maronna . Another purported Oscan influence is the historical assimilation of the consonant cluster /nd/ as /nn/ , pronounced [nː] (this is generally reflected in spelling more consistently: munno vs Italian mondo "world"; quanno vs Italian quando "when"), along with

The system's initial, 8-kilometre-long (5.0 mi) route has been constructed. It connects the city center, including the Pescara Centrale railway station , with Montesilvano . New Van Hool trolleybuses for use on the route have been delivered. Once these have been tested and driver training completed, service will start, possibly in 2023 or 2024. A future extension to

There are two models of cyclone development and life cycles in common use: the Norwegian model and the Shapiro–Keyser model. Of the two theories on extratropical cyclone structure and life cycle, the older is the Norwegian Cyclone Model, developed during World War I . In this theory, cyclones develop as they move up and along

Hurricane-force extratropical cyclones are most likely to form in the northern Atlantic and northern Pacific oceans in the months of December and January. On 14 and 15 December 1986, an extratropical cyclone near Iceland deepened to below 920 millibars (27 inHg), which is a pressure equivalent to

Also from the north east comes winter weather from Siberia that, on average, brings abundant snowfalls every 3–4 years. In summer the weather is mostly stable and sunny with temperatures that, thanks to the sea breeze, rarely exceed 35 degrees unless a southwesterly Libeccio is blowing. Particularly in summer, but also in winter,

3552-560: Is known as a " zonal flow regime ". When the general flow pattern buckles from a zonal pattern to the meridional pattern, a slower movement in a north or southward direction is more likely. Meridional flow patterns feature strong, amplified troughs and ridges, generally with more northerly and southerly flow. Changes in direction of this nature are most commonly observed as a result of a cyclone's interaction with other low pressure systems , troughs , ridges , or with anticyclones . A strong and stationary anticyclone can effectively block
3663-470: Is known as the cold sector, while the area equatorward and east of its associated cold and warm fronts is known as the warm sector. The wind flow around an extratropical cyclone is counterclockwise in the northern hemisphere, and clockwise in the southern hemisphere, due to the Coriolis effect (this manner of rotation is generally referred to as cyclonic ). Near this center, the pressure gradient force (from

The windfield of an extratropical cyclone constricts with distance in relation to surface level pressure, with the lowest pressure being found near the center, and the highest winds typically just on the cold/poleward side of warm fronts, occlusions, and cold fronts , where the pressure gradient force is highest. The area poleward and west of the cold and warm fronts connected to extratropical cyclones

4551-982: The Northern Hemisphere and 71,289–74,229 extratropical cyclones in the Southern Hemisphere were detected between 1979 and 2018 based on reanalysis data. A study of extratropical cyclones in the Southern Hemisphere shows that between the 30th and 70th parallels , there are an average of 37 cyclones in existence during any 6-hour period. A separate study in the Northern Hemisphere suggests that approximately 234 significant extratropical cyclones form each winter. Extratropical cyclones form along linear bands of temperature/dew point gradient with significant vertical wind shear , and are thus classified as baroclinic cyclones. Initially, cyclogenesis , or low pressure formation, occurs along frontal zones near

During this process, a cyclone in extratropical transition (known across the eastern North Pacific and North Atlantic oceans as the post-tropical stage), will invariably form or connect with nearby fronts and/or troughs consistent with a baroclinic system. Due to this, the size of the system will usually appear to increase, while

It can also be the focus of locally heavy precipitation, with thunderstorms possible if the atmosphere along the trowal is unstable enough for convection. Extratropical cyclones slant back into colder air masses and strengthen with height, sometimes exceeding 30,000 feet (approximately 9 km) in depth. Above

In the case of ’o , which can be either masculine singular or neuter singular (there is no neuter plural in Neapolitan), the initial consonant of the noun is doubled when it is neuter. For example, the name of a language in Neapolitan is always neuter, so if we see ’o nnapulitano we know it refers to
5328-468: The sea surface temperature is the greatest, leading to the greatest potential for instability. On rare occasions, an extratropical cyclone can transform into a tropical cyclone if it reaches an area of ocean with warmer waters and an environment with less vertical wind shear. An example of this happening is in the 1991 Perfect Storm . The process known as "tropical transition" involves the usually slow development of an extratropically cold core vortex into

Also, the XT technique is only used once extratropical transition begins; the Dvorak technique is still used if the system begins dissipating without transition. Once the cyclone has completed transition and become cold-core , the technique

Likewise, since ’e can be either masculine or feminine plural, when it is feminine plural, the initial consonant of the noun is doubled. For example, consider ’a lista , which in Neapolitan is feminine singular, meaning "the list". In the plural, it becomes ’e lliste . There can also be problems with nouns whose singular form ends in e . Since plural nouns usually end in e whether masculine or feminine,

7215-419: The cooler air ahead of the system is denser , and therefore more difficult to dislodge. Later, the cyclones occlude as the poleward portion of the cold front overtakes a section of the warm front, forcing a tongue, or trowal , of warm air aloft. Eventually, the cyclone will become barotropically cold and begin to weaken. Atmospheric pressure can fall very rapidly when there are strong upper level forces on
7326-413: The core weakens. However, after transition is complete, the storm may re-strengthen due to baroclinic energy, depending on the environmental conditions surrounding the system. The cyclone will also distort in shape, becoming less symmetric with time. During extratropical transition, the cyclone begins to tilt back into the colder airmass with height, and the cyclone's primary energy source converts from
7437-422: The cyclone (a low pressure system). The lowered pressure acts to draw in air, creating convergence in the low-level wind field. Low-level convergence and upper-level divergence imply upward motion within the column, making cyclones cloudy.

In the city center is located the headquarters of ICRANet , the International Center for Relativistic Astrophysics Network, an international organization promoting research activities in relativistic astrophysics and related areas. The city has a football team, Delfino Pescara 1936 , which in June 2012 was promoted to Serie A , the highest league in Italy . Pescara Calcio, who have played 38 seasons in
8103-418: The first time in this period. Several seignors ruled over Pescara afterwards, including Rainaldo Orsini , Louis of Savoy , and Francesco del Borgo , the vicar of king Ladislaus of Naples , who had the fortress and the tower built. The subsequent rulers were the D'Avalos . In 1424 the famous condottiero Muzio Attendolo died here. Another adventurer, Jacopo Caldora , conquered the town in 1435 and 1439. In
8214-636: The following years Pescara was repeatedly attacked by the Venetians , and later, as part of the Spanish Kingdom of Naples , it was turned into a massive fortress . In 1566 it was besieged by 105 Turk galleys . It resisted fiercely and the Ottomans only managed to ravage the surrounding territory. At the beginning of the 18th century Pescara had some 3,000 inhabitants, half of them living in Castellammare,
8325-527: The fortress was dismantled. In the sixty following years Pescara was included in the Province of Chieti and then merged with the adjacent town of Castellammare Adriatico and eventually became the largest city of its region. The new city suffered heavy civilian casualties when it was bombed by the Allies who were attempting to cut German supply lines during World War II . It has since been massively rebuilt, becoming
8436-635: The high humidity leads to morning and evening mist or haze. Pescara's origins precede the Roman conquest. It was founded to be the port of Vestini and Marrucini tribes to trade with the peoples of the Orient, a supporting role that was held for centuries. The name of both the town and the river was Aternum , it was connected to Rome through the Via Claudia Valeria and the Via Tiburtina . The main building
8547-472: The higher latitudes). The existence of such transients are also closely related to the formation of the Icelandic and Aleutian Low — the two most prominent general circulation features in the mid- to sub-polar northern latitudes. The two lows are formed by both the transport of kinetic energy and the latent heating (the energy released when water phase changed from vapor to liquid during precipitation) from
8658-471: The increasing displacement of Neapolitan by Standard Italian in daily speech . Neapolitan is a Romance language and is considered as part of Southern Italo-Romance. There are notable differences among the various dialects, but they are all generally mutually intelligible. Italian and Neapolitan are of variable mutual comprehensibility, depending on affective and linguistic factors. There are notable grammatical differences, such as Neapolitan having nouns in
8769-511: The intransitive and reflexive verbs take èssere for their auxiliary. For example, we have: Aggio AUX .have. 1SG . PRES stato be. PTCP . PAST a in Napule Naples ajere. yesterday Aggio stato a Napule ajere. AUX.have.1SG.PRES be.PTCP.PAST in Naples yesterday I was in Naples yesterday. Sono AUX .be. 1S . PRES stato be. PTCP . PAST
8880-659: The late autumn. Pescara is a coastal city, but its climate is influenced by the surrounding mountains (the Maiella and the chain of Gran Sasso ). When the wind is southwesterly, Pescara experiences a Foehn wind that often reaches 100 km/h (62 mph), causing a sudden increase in temperature and decrease in relative humidity, and for that reason winters with temperatures that exceed 20 °C (68 °F) almost daily are not unknown. Pescara experiences 35 days annually with minimum temperature below 0 °C (32 °F). Under northeasterly winds Pescara suffers precipitation which
8991-426: The letter j . The following English pronunciation guidelines are based on General American pronunciation, and the values used may not apply to other dialects. (See also: International Phonetic Alphabet chart for English dialects .) All Romance languages are closely related. Although Neapolitan shares a high degree of its vocabulary with Italian, the official language of Italy, differences in pronunciation often make
9102-420: The letter s as [ ʃ ] (like the sh in ship ) instead of / s / (like the s in sea or the ss in pass ) when the letter is in initial position followed by a consonant, but not when it is followed by a dental occlusive / t / or / d / (at least in the purest form of the language) but by otherwise using only entirely standard words and grammatical forms. This is not Neapolitan properly, but rather
9213-530: The local Chamber of Commerce , of the Liceo Classico "G. D'Annunzio" high school, and the old seat of the court (which now houses a museum). In the far southern part of the city, between the Nature Reserve Pineta Dannunziana and the beach, there is an elegant Art Nouveau villas district designed in 1912 by Antonino Liberi (an engineer brother-in-law of D'Annunzio). There is also the Aurum, first headquarters of
9324-628: The main dedicated international magazines. Every year (between June and July) the city also holds the Flaiano Prizes , one of Italy's International Film Festivals. Pescara was the birthplace of Gabriele D'Annunzio and Ennio Flaiano . Vittoria Colonna was the marchioness of Pescara. Pescara and Chieti are the homes of the G. d'Annunzio University . Pescara is home to the Departments of Architecture, Economics, Business Administration, Quantitative Economics, Social and Legal Sciences, Modern Languages Literatures and Cultures, as Chieti, together with
9435-406: The masculine plural is often signaled orthographically, that is, by altering the spelling. As an example, consider the word guaglione , which means "boy" or (in the feminine form) "girl": More will be said about these orthographically changing nouns in the section on Neapolitan nouns. A couple of notes about consonant doubling: The Neapolitan indefinite articles, corresponding to the English
9546-733: The mid- latitude cyclones. The most intense extratropical cyclone on record was a cyclone in the Southern Ocean in October 2022. An analysis by the European Centre for Medium-Range Weather Forecasts estimated a pressure of 900.7 mbar (26.60 inHg) and a subsequent analysis published in Geophysical Research Letters estimated a pressure of 899.91 mbar (26.574 inHg). The same Geophysical Research Letters article notes at least five other extratropical cyclones in
9657-562: The most damaging flood in European since at least 1985. In late December 1999, Cyclones Lothar and Martin caused 140 deaths combined and over $ 23 billion in damages in Central Europe, the costliest European windstorms in history. In October 2012, Hurricane Sandy transitioned into an extratropical cyclone off the coast of the Northeastern United States . The storm killed over 100 people and caused $ 65 billion in damages,
9768-593: The national level to have it recognized as an official minority language of Italy. It is a recognized ISO 639 Joint Advisory Committee language with the ISO 639-3 language code of nap . Here is the IPA pronunciation of the Neapolitan spoken in the city of Naples: Neapolitan orthography consists of 22 Latin letters. Much like Italian orthography , it does not contain k, w, x, or y even though these letters might be found in some foreign words; unlike Italian, it does contain
9879-502: The neuter form and a unique plural formation, as well as historical phonological developments, which often obscure the cognacy of lexical items. Its evolution has been similar to that of Italian and other Romance languages from their roots in Vulgar Latin . It may reflect a pre-Latin Oscan substratum , as in the pronunciation of the d sound as an r sound ( rhotacism ) at the beginning of
9990-614: The north shore of the river there's Piazza Italia (Italy Square), overlooked by the City Hall and the Government Building (which houses the headquarters of the Province of Pescara ), both built during the Fascist era according to the fascist rationalist style and designed by the architect Vincenzo Pilotti. Pilotti designed the majority of the public buildings of the city, including the seat of
10101-467: The oceans is the Shapiro–Keyser model, developed in 1990. Its main differences with the Norwegian Cyclone Model are the fracture of the cold front, treating warm-type occlusions and warm fronts as the same, and allowing the cold front to progress through the warm sector perpendicular to the warm front. This model was based on oceanic cyclones and their frontal structure, as seen in surface observations and in previous projects which used aircraft to determine
10212-401: The part of the cold front ahead of the cyclone will develop into a warm front, giving the frontal zone (as drawn on surface weather maps ) a wave-like shape. Due to their appearance on satellite images, extratropical cyclones can also be referred to as frontal waves early in their life cycle. In the United States , an old name for such a system is "warm wave". In the northern hemisphere, once
10323-572: The path of an extratropical cyclone. Such blocking patterns are quite normal, and will generally result in a weakening of the cyclone, the weakening of the anticyclone, a diversion of the cyclone towards the anticyclone's periphery, or a combination of all three to some extent depending on the precise conditions. It is also common for an extratropical cyclone to strengthen as the blocking anticyclone or ridge weakens in these circumstances. Where an extratropical cyclone encounters another extratropical cyclone (or almost any other kind of cyclonic vortex in
10434-515: The penultimate round of the World Championship of Drivers . Since 2011 the Italian edition of the Ironman 70.3 takes place in the city of Pescara, chosen for the characteristics of the territory, for the possibility of building a competition that starts from the sea, continue towards the mountains and ends in the city center. As regards public transport Pescara has a wide assortment of services,
10545-466: The pressure at the center of the cyclone compared to the pressure outside the cyclone) and the Coriolis force must be in an approximate balance for the cyclone to avoid collapsing in on itself as a result of the difference in pressure. The central pressure of the cyclone will lower with increasing maturity, while outside of the cyclone, the sea-level pressure is about average. In most extratropical cyclones,
10656-470: The pronunciation is different for the two. The grave accent ( à , è , ò ) is used to denote open vowels, and the acute accent ( é , í , ó , ú ) is used to denote closed vowels, with alternative ì and ù . However, accent marks are not commonly used in the actual spelling of words except when they occur on the final syllable of a word, such as Totò , arrivà , or pecché , and when they appear here in other positions, it
10767-564: The province are in Piazza Italia, near the river, and in the area between here and the D'Annunzio University campus to the south, a business district has grown up over the years, while the Marina is situated to the immediate south of the mouth of the river. Pescara is also served by an international airport, the Abruzzo Airport , and one of the major touristic ports of Adriatic Sea and Italy,
10878-468: The release of latent heat from condensation (from thunderstorms near the center) to baroclinic processes. The low pressure system eventually loses its warm core and becomes a cold-core system . The peak time of subtropical cyclogenesis (the midpoint of this transition) in the North Atlantic is in the months of September and October, when the difference between the temperature of the air aloft and
10989-627: The remains of the Norman and Byzantine city walls). Today it houses the Museum of the Abruzzi people : the institution traces, through 13 halls dedicated to aspects of life, traditions and economy, 4,000 years of history of the Abruzzo people. In the historic city center are the birthplace houses of Gabriele D'Annunzio and Ennio Flaiano , and the San Cetteo Cathedral , built between 1933 and 1938. On
11100-466: The seacoast in Piazza Primo Maggio . The rectangle that it forms with Corso Vittorio Emanuele II and Via Nicola Fabrizi is home of the main shopping district, enclosed in a driving restriction zone , where several of the best fashion shops are located. Corso Manthoné, the course of the old Pescara, has, for many years, been the center of the nightlife of the city. City hall and the administration of
11211-485: The second costliest tropical cyclone at the time. Other extratropical cyclones have been related to major tornado outbreaks . The tornado outbreaks of April 1965 , April 1974 and April 2011 were all large, violent, and deadly tornado outbreaks related to extratropical cyclones. Similarly, winter storms in March 1888 , November 1950 and March 1993 were responsible for over 300 deaths each. In December 1960
11322-431: The size of the two cyclones, their strength, their distance from each other, and the prevailing atmospheric conditions around them. Extratropical cyclones can bring little rain and surface winds of 15–30 km/h (10–20 mph), or they can be dangerous with torrential rain and winds exceeding 119 km/h (74 mph), and so they are sometimes referred to as windstorms in Europe. The band of precipitation that
11433-568: The songs of Pino Daniele and the Nuova Compagnia di Canto Popolare . The language has no official status within Italy and is not taught in schools. The University of Naples Federico II offers (from 2003) courses in Campanian Dialectology at the faculty of Sociology, whose actual aim is not to teach students to speak the language but to study its history, usage, literature and social role. There are also ongoing legislative attempts at
11544-441: The surface of the earth, the air temperature near the center of the cyclone is increasingly colder than the surrounding environment. These characteristics are the direct opposite of those found in their counterparts, tropical cyclones ; thus, they are sometimes called "cold-core lows". Various charts can be examined to check the characteristics of a cold-core system with height, such as the 700 millibars (20.67 inHg) chart, which
11655-493: The system. When pressures fall more than 1 millibar (0.030 inHg ) per hour, the process is called explosive cyclogenesis, and the cyclone can be described as a bomb . These bombs rapidly drop in pressure to below 980 millibars (28.94 inHg) under favorable conditions such as near a natural temperature gradient like the Gulf Stream , or at a preferred quadrant of an upper-level jet streak, where upper level divergence
11766-502: The systems can cause significant floods overland because of torrential rainfall. The July 2016 North China cyclone never brought gale -force sustained winds, but it caused devastating floods in mainland China , resulting in at least 184 deaths and ¥ 33.19 billion ( US$ 4.96 billion) of damage. An emerging topic is the co-occurrence of wind and precipitation extremes, so-called compound extreme events, induced by extratropical cyclones. Such compound events account for 3–5% of
11877-456: The total number of cyclones. In the classic analysis by Edward Lorenz (the Lorenz energy cycle ), extratropical cyclones (so-called atmospheric transients) acts as a mechanism in converting potential energy that is created by pole to equator temperature gradients to eddy kinetic energy. In the process, the pole-equator temperature gradient is reduced (i.e. energy is transported poleward to warm up
11988-550: The vertical structure of fronts across the northwest Atlantic. A warm seclusion is the mature phase of the extratropical cyclone life cycle. This was conceptualized after the ERICA field experiment of the late 1980s, which produced observations of intense marine cyclones that indicated an anomalously warm low-level thermal structure, secluded (or surrounded) by a bent-back warm front and a coincident chevron-shaped band of intense surface winds. The Norwegian Cyclone Model , as developed by

Neapolitan has enjoyed a rich literary, musical and theatrical history (notably Giambattista Basile , Eduardo Scarpetta , his son Eduardo De Filippo , Salvatore Di Giacomo and Totò ). Thanks to this heritage and the musical work of Renato Carosone in the 1950s, Neapolitan is still in use in popular music, even gaining national popularity in
12210-466: Was executed by the Lombards at Amiternum by being thrown off a bridge with a stone tied around his neck; his body floated to Pescara. In 1095 Pescara was a fishing village enriched with monuments and churches. In 1140 Roger of Sicily conquered the town, giving rise to a period in which it was destroyed by armies ravaging the Kingdom of Sicily . The name of Piscaria ("abounding with fish") is mentioned for
12321-722: Was the temple of Jovis Aternium . The town was an important port for trade with the Eastern provinces of the Empire. In the Middle Ages it was destroyed by the Lombards (597). Saint Cetteus , the town's patron saint, was a bishop of the 6th century, elected to the see of Amiternum in Sabina (today the city of San Vittorino ) in 590, during the pontificate of Gregory the Great . His legend goes that he
