86-560: In the late 18th century, Kanchanaburi was established by King Rama I as a defensive outpost against possible Burmese attacks in what is now Lat Ya Sub-district. In 1833, the town was moved about 16 km to the southeast along the river to its present site during the reign of King Rama III . From the Ayutthaya period to the Thonburi and Rattanakosin periods, Kanchanaburi was an important outpost to defend against Burmese invasions . The old town

172-720: A tropical savanna climate ( Köppen climate classification Aw ). Winters are dry and very warm. Temperatures rise until April, which is very hot with the average daily maximum at 38.2 °C (100.8 °F). The monsoon season runs from May through October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm. 14°1′10″N 99°31′52″E  /  14.01944°N 99.53111°E  / 14.01944; 99.53111 Buddha Yodfa Chulaloke Phra Bat Somdet Phra Phutthayotfa Chulalok Maharat ( Thai : พระบาทสมเด็จพระพุทธยอดฟ้าจุฬาโลกมหาราช , 20 March 1737 – 7 September 1809), personal name Thongduang ( ทองด้วง ), also known as Rama I ,

258-596: A concentrated belt that stretches east–west except in East China where it is tilted east-northeast over Korea and Japan. The seasonal rain is known as Meiyu in China, Jangma in Korea, and Bai-u in Japan, with the latter two resembling frontal rain. The onset of the summer monsoon is marked by a period of premonsoonal rain over South China and Taiwan in early May. From May through August,

344-469: A different stage of his life. It is the easiest access point to the nearby Tiger Temple (closed) and is also home to a Vipassana meditation center. In 1942 Kanchanaburi was under Japanese control. It was here that Asian forced labourers and Allied POWs , building the infamous Burma Railway , constructed a bridge, an event fictionalised in the films The Bridge on the River Kwai (1957), Return from

430-410: A dominant westerly component and a strong tendency to ascend and produce copious amounts of rain (because of the condensation of water vapor in the rising air). The intensity and duration, however, are not uniform from year to year. Winter monsoons, by contrast, have a dominant easterly component and a strong tendency to diverge, subside and cause drought. Similar rainfall is caused when moist ocean air

516-598: A few sub-systems, such as the Indian Subcontinental Monsoon which affects the Indian subcontinent and surrounding regions including Nepal, and the East Asian Monsoon which affects southern China, Taiwan , Korea and parts of Japan. The southwestern summer monsoons occur from June through September. The Thar Desert and adjoining areas of the northern and central Indian subcontinent heat up considerably during

602-535: A low pressure system known as a monsoon trough develops over South-East Asia and Australasia and winds are directed toward Australia. In the Philippines, northeast monsoon is called Amihan . The East Asian monsoon affects large parts of Indochina , the Philippines , China, Taiwan , Korea, Japan, and Siberia . It is characterised by a warm, rainy summer monsoon and a cold, dry winter monsoon. The rain occurs in

688-517: A monk temporarily, in accordance with Siamese custom. In 1760, he married Nak , daughter of a town patron in Samut Sakorn. He was later appointed the Luang Yokkrabat (deputy governor) of Ratchaburi Province by King Ekkathat in 1758. On the eve of the fall of Ayutthaya, Phraya Wachiraprakan (later King Taksin ) had foreseen that the fall of the city was certain. Wachiraprakan decided to break

774-464: A more even temperature, while land temperatures are more variable. During warmer months sunlight heats the surfaces of both land and oceans, but land temperatures rise more quickly. As the land's surface becomes warmer, the air above it expands and an area of low pressure develops. Meanwhile, the ocean remains at a lower temperature than the land, and the air above it retains a higher pressure. This difference in pressure causes sea breezes to blow from

860-662: A note. Ánh managed to recapture Saigon by 1788 and later ascended as Emperor Gia Long in 1802. In 1794, upon Ang Eng's majority, Rama I reinstalled him as the Neareay Reachea III. The area around Siem Reap and Battambang was annexed by Siam, and were governed by Abhaya Bhubet. However, Rama I allowed these territories to be ruled in accordance with Cambodian traditions. Soon King Bodawpaya of Burma started to pursue his ambitious campaigns to expand his dominions over Siam. The Burmese–Siamese War (1785–1786) , also known in Siam as

946-462: A revival of Siamese culture and state organization following the collapse of the Siamese kingdom in 1767, whose capital was then situated at Ayutthaya. He established a new purified Buddhist sect which allied and tied together Buddhism and the monarchy. Rama I consolidated and expanded on Taksin's military campaigns throughout Mainland Southeast Asia, whose mandala in 1809 stretched as far North and South as

1032-650: A seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African , Asian– Australian , the North American , and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from

At night there is a small pyrotechnics display that re-enacts the wartime bombing of the bridge. The riverfront has skywalk, and next to it is Walking Street. The skywalk is a "12-metre high and 150 metre-long" glass walkway , owned by

1204-556: A strategic plan and under it recaptured Ayutthaya in one year. In 1768 Taksin crowned himself and founded the Kingdom of Thonburi on the west bank of the mouth of the Chao Phraya river, using Thonburi as a new capital. Under the new Thonburi regime, Thongduang was appointed head of the royal police department, bearing the title Phra Ratcharin . After subjugating the warlord of Phimai with his brother Bunma (at that time called Phra Mahamontri,

1290-571: A timing of the monsoon beginning 15–20 million years ago and linked to early Tibetan uplift. Testing of this hypothesis awaits deep ocean sampling by the Integrated Ocean Drilling Program . The monsoon has varied significantly in strength since this time, largely linked to global climate change , especially the cycle of the Pleistocene ice ages. A study of Asian monsoonal climate cycles from 123,200 to 121,210 years BP, during

1376-620: A weakening of the Leeuwin Current (LC). The weakening of the LC would have an effect on the sea surface temperature (SST) field in the Indian Ocean, as the Indonesian Throughflow generally warms the Indian Ocean. Thus these five intervals could probably be those of considerable lowering of SST in the Indian Ocean and would have influenced Indian monsoon intensity. During the weak LC, there

In March 2003, the Thailand–Burma Railway Centre opened and the JEATH (Japanese-English-American-Australian-Thai-Holland) War Museum dedicated to the bridge and the Death Railway . The city is also home to the Kanchanaburi War Cemetery . The Chungkai War Cemetery is located about 5 kilometres (3.1 mi) from Kanchanaburi. Kanchanaburi has

1548-652: Is directly of "cyclonic" (i.e., monsoon-driven) origin (as opposed to " local convection "). The effects also extend westwards to the Mediterranean, where however the impact of the monsoon is to induce drought via the Rodwell-Hoskins mechanism . Around September, with the sun retreating south, the northern landmass of the Indian subcontinent begins to cool off rapidly, and air pressure begins to build over northern India. The Indian Ocean and its surrounding atmosphere still hold their heat, causing cold wind to sweep down from

1634-521: Is lifted upwards by mountains, surface heating, convergence at the surface, divergence aloft, or from storm-produced outflows at the surface. However the lifting occurs, the air cools due to expansion in lower pressure, and this produces condensation . The monsoon of western Sub-Saharan Africa is the result of the seasonal shifts of the Intertropical Convergence Zone and the great seasonal temperature and humidity differences between

1720-577: Is the possibility of reduced intensity of the Indian winter monsoon and strong summer monsoon, because of change in the Indian Ocean dipole due to reduction in net heat input to the Indian Ocean through the Indonesian Throughflow. Thus a better understanding of the possible links between El Niño , Western Pacific Warm Pool, Indonesian Throughflow, wind pattern off western Australia, and ice volume expansion and contraction can be obtained by studying

1806-410: Is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of

1892-567: The Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. The etymology of the word monsoon is not wholly certain. The English monsoon came from Portuguese monção ultimately from Arabic موسم ( mawsim , "season"), "perhaps partly via early modern Dutch monson ". Strengthening of the Asian monsoon has been linked to the uplift of the Tibetan Plateau after

1978-601: The Eemian interglacial, suggests that they had an average duration of around 64 years, with the minimum duration being around 50 years and the maximum approximately 80 years, similar to today. A study of marine plankton suggested that the South Asian Monsoon (SAM) strengthened around 5 million years ago. Then, during ice periods, the sea level fell and the Indonesian Seaway closed. When this happened, cold waters in

2064-727: The Hadley circulation during boreal winter. It is associated with the development of the Siberian High and the movement of the heating maxima from the Northern Hemisphere to the Southern Hemisphere. North-easterly winds flow down Southeast Asia, are turned north-westerly/westerly by Borneo topography towards Australia. This forms a cyclonic circulation vortex over Borneo, which together with descending cold surges of winter air from higher latitudes, cause significant weather phenomena in

2150-558: The Himalayas and Indo-Gangetic Plain towards the vast spans of the Indian Ocean south of the Deccan peninsula. This is known as the Northeast Monsoon or Retreating Monsoon. While travelling towards the Indian Ocean, the cold dry wind picks up some moisture from the Bay of Bengal and pours it over peninsular India and parts of Sri Lanka . Cities like Chennai , which get less rain from

2236-514: The Khwae Noi and Khwae Yai Rivers converge into the Mae Klong River, spans the northern banks of the river and is a popular spot for travelers. Its location at the edge of a mountain range keeps it much cooler than the other provinces of central Thailand. The city has two major commercial districts: the downtown area consists of a grid of several streets with office buildings, shop fronts, and

2322-772: The Sahara and the equatorial Atlantic Ocean. The ITCZ migrates northward from the equatorial Atlantic in February, reaches western Africa on or near June 22, then moves back to the south by October. The dry, northeasterly trade winds , and their more extreme form, the harmattan , are interrupted by the northern shift in the ITCZ and resultant southerly, rain-bearing winds during the summer. The semiarid Sahel and Sudan depend upon this pattern for most of their precipitation. The North American monsoon ( NAM ) occurs from late June or early July into September, originating over Mexico and spreading into

His reign also marked the beginning of a new "Golden Age of Culture", which continued in the footsteps of the blossoming of the arts during the Late Ayutthaya Period. Like other high-ranking figures of old Siam, Rama I's name changed several times during his lifetime, depending on his respective position, and even posthumously. His name at birth

2494-604: The return of the westerlies ) is the result of a resurgence of westerly winds from the Atlantic, where they become loaded with wind and rain. These westerly winds are a common phenomenon during the European winter, but they ease as spring approaches in late March and through April and May. The winds pick up again in June, which is why this phenomenon is also referred to as "the return of the westerlies". The rain usually arrives in two waves, at

2580-510: The "Nine Armies War" because the Burmese came in nine armies, broke out. The Burmese soldiers poured into Lanna and Northern Siam. Siamese forces, commanded by Kawila, Prince of Lampang , put up a brave fight and delayed the Burmese advance, all the while waiting for reinforcements from Bangkok. When Phitsanulok was captured, Anurak Devesh the Rear Palace , and Rama I himself led Siamese forces to

He appointed his brother Surasi (Anuchit Raja) or Maha Sura Singhanat as the " Front Palace " (conventional title of

2838-686: The EASM grew in strength, but it has been suggested to have decreased in strength during Heinrich events . The EASM expanded its influence deeper into the interior of Asia as sea levels rose following the LGM; it also underwent a period of intensification during the Middle Holocene, around 6,000 years ago, due to orbital forcing made more intense by the fact that the Sahara at the time was much more vegetated and emitted less dust. This Middle Holocene interval of maximum EASM

2924-579: The East Asian Winter Monsoon (EAWM) became stronger as the subarctic front shifted southwards. An abrupt intensification of the EAWM occurred 5.5 million years ago. The EAWM was still significantly weaker relative to today between 4.3 and 3.8 million years ago but abruptly became more intense around 3.8 million years ago as crustal stretching widened the Tsushima Strait and enabled greater inflow of

A delay of a few days in the arrival of the monsoon can badly affect the economy, as evidenced in the numerous droughts in India in the 1990s. The monsoon is widely welcomed and appreciated by city-dwellers as well, for it provides relief from

3096-799: The Late Holocene, significant glacial accumulation in the Himalayas still occurred due to cold temperatures brought by westerlies from the west. During the Middle Miocene , the July ITCZ, the zone of rainfall maximum, migrated northwards, increasing precipitation over southern China during the East Asian Summer Monsoon (EASM) while making Indochina drier. During the Late Miocene Global Cooling (LMCG), from 7.9 to 5.8 million years ago,

3182-498: The Pacific were impeded from flowing into the Indian Ocean. It is believed that the resulting increase in sea surface temperatures in the Indian Ocean increased the intensity of monsoons. In 2018, a study of the SAM's variability over the past million years found that precipitation resulting from the monsoon was significantly reduced during glacial periods compared to interglacial periods like

He then seized power and made himself King, establishing the Chakri dynasty , which continues to rule Thailand to this day. General Maha Kasatsuek crowned himself on 6 April 1782. Soon after, he decided to move the capital of Siam to the east bank of

There were four POW camps in or near the city, including Tamarkan which was used as a work camp to construct the bridge. After the completion of the railway line, most prisoners were concentrated in the Kanchanaburi area, and often sent on to Japan or French Indo-China . At Kanchanaburi, there

King Rama I died on 7 September 1809 after a short but acute illness; he was succeeded by his son Prince Isarasundhorn as Buddha Loetla Nabhalai or Rama II. Siam during the reign of Rama I reached a new height of power not seen since

3612-593: The Southwest Monsoon first hits the Western Ghats of the coastal state of Kerala , India, thus making this area the first state in India to receive rain from the Southwest Monsoon. This branch of the monsoon moves northwards along the Western Ghats ( Konkan and Goa ) with precipitation on coastal areas, west of the Western Ghats. The eastern areas of the Western Ghats do not receive much rain from this monsoon as

3698-535: The Southwest Monsoon, receive rain from this Monsoon. About 50% to 60% of the rain received by the state of Tamil Nadu is from the Northeast Monsoon. In Southern Asia, the northeastern monsoons take place from October to December when the surface high-pressure system is strongest. The jet stream in this region splits into the southern subtropical jet and the polar jet. The subtropical flow directs northeasterly winds to blow across southern Asia, creating dry air streams which produce clear skies over India. Meanwhile,

3784-458: The air temperature remains relatively stable for two reasons: water has a relatively high heat capacity (3.9 to 4.2 J g K ), and because both conduction and convection will equilibrate a hot or cold surface with deeper water (up to 50 metres). In contrast, dirt, sand, and rocks have lower heat capacities (0.19 to 0.35 J g K ), and they can only transmit heat into the earth by conduction and not by convection. Therefore, bodies of water stay at

June 1 is regarded as the date of onset of the monsoon in India, as indicated by the arrival of the monsoon in the southernmost state of Kerala. The monsoon accounts for nearly 80% of the rainfall in India. Indian agriculture (which accounts for 25% of

3956-507: The beginning of June, and again in mid- to late June. The European monsoon is not a monsoon in the traditional sense in that it doesn't meet all the requirements to be classified as such. Instead, the return of the westerlies is more regarded as a conveyor belt that delivers a series of low-pressure centres to Western Europe where they create unsettled weather. These storms generally feature significantly lower-than-average temperatures, fierce rain or hail, thunder, and strong winds. The return of

4042-414: The behaviour of the LC during Quaternary at close stratigraphic intervals. The South American summer monsoon (SASM) is known to have become weakened during Dansgaard–Oeschger events. The SASM has been suggested to have been enhanced during Heinrich events. Monsoons were once considered as a large-scale sea breeze caused by higher temperature over land than in the ocean. This is no longer considered as

4128-648: The cause and the monsoon is now considered a planetary-scale phenomenon involving the annual migration of the Intertropical Convergence Zone between its northern and southern limits. The limits of the ITCZ vary according to the land–sea heating contrast and it is thought that the northern extent of the monsoon in South Asia is influenced by the high Tibetan Plateau. These temperature imbalances happen because oceans and land absorb heat in different ways. Over oceans,

As his armies were destroyed, Bodawpaya retreated. The next year, he attacked again, this time constituting his troops as a single army. With this force Bodawpaya passed through the Chedi Sam Ong pass and settled in Tha Din Daeng. The Front Palace marched

4300-609: The climax of summer heat in June. However, the roads take a battering every year. Often houses and streets are waterlogged and slums are flooded despite drainage systems. A lack of city infrastructure coupled with changing climate patterns causes severe economic loss including damage to property and loss of lives, as evidenced in the 2005 flooding in Mumbai that brought the city to a standstill. Bangladesh and certain regions of India like Assam and West Bengal , also frequently experience heavy floods during this season. Recently, areas in India that used to receive scanty rainfall throughout

4386-399: The colder months, the cycle is reversed. Then the land cools faster than the oceans and the air over the land has higher pressure than air over the ocean. This causes the air over the land to flow to the ocean. When humid air rises over the ocean, it cools, and this causes precipitation over the oceans. (The cool air then flows towards the land to complete the cycle.) Most summer monsoons have

4472-417: The collision of the Indian subcontinent and Asia around 50 million years ago. Because of studies of records from the Arabian Sea and that of the wind-blown dust in the Loess Plateau of China, many geologists believe the monsoon first became strong around 8 million years ago. More recently, studies of plant fossils in China and new long-duration sediment records from the South China Sea led to

4558-403: The founder of Rattanakosin (now Bangkok ) as the new capital of the reunited kingdom. Rama I, whose given name was Thongduang, was born from a Mon male line descent family, great-grandson of Kosa Pan . His father served in the royal court of the Ayutthaya Kingdom . Thongduang and his younger brother Boonma served King Taksin in wars against the Burmese Konbaung dynasty and helped him in

After the campaign to subdue the lord of Fang in 1769, Thongduang was raised to Phraya Yommarat and in the next year became Chao Phraya Chakri – the Samuhanayok (chief minister of the northern provinces). Chakri commanded the Siamese troops in the wars against Burma and went on to subjugate Cambodia . His brother Bunma (who by that time held

4730-459: The hot summers. This causes a low pressure area over the northern and central Indian subcontinent. To fill this void, the moisture-laden winds from the Indian Ocean rush into the subcontinent. These winds, rich in moisture, are drawn towards the Himalayas . The Himalayas act like a high wall, blocking the winds from passing into Central Asia, and forcing them to rise. As the clouds rise, their temperature drops, and precipitation occurs . Some areas of

However, the joint Nguyễn-Siam fleet was destroyed in the Battle of Rach Gam–Xoai Mut in the Mekong Delta region. Nguyễn's appeal for Siamese assistance enabled the Siamese to exert considerable political influence over Nguyễn's court. Mac Tu Sinh ,

Upon hearing the news, the governors of Phatthalung fled. However, a monk named Phra Maha encouraged

5074-444: The monsoon is not a simple response to heating but a more complex interaction of topography, wind and sea, as demonstrated by its abrupt rather than gradual withdrawal from the region. The Australian monsoon (the "Wet") occurs in the southern summer when the monsoon trough develops over Northern Australia . Over three-quarters of annual rainfall in Northern Australia falls during this time. The European Monsoon (more commonly known as

The January ITCZ migrated further south to its present location during the Middle Miocene, strengthening the summer monsoon of Australia that had previously been weaker. Five episodes during the Quaternary at 2.22 Ma ( PL-1), 1.83 Ma (PL-2), 0.68 Ma (PL-3), 0.45 Ma (PL-4) and 0.04 Ma (PL-5) were identified which showed

However, when the air rises, and while it is still over the land, the air cools . This decreases the air's ability to hold water , and this causes precipitation over the land. This is why summer monsoons cause so much rain over land. In

Thongduang was the first Somdet Chao Phraya , the highest rank the nobility could attain, equaled to that of royalty. In 1782, he took control of Siam and crowned himself as the monarch. The most famous event in his reign was the Burmese–Siamese War (1785–1786) , which was the last major Burmese assault on Siam. Rama I's reign marked

The one dedicated to the first Chakri king was named Phra Phutthayotfa Chulalok ("the Buddha on top of the sky and the crown of the worlds"). This is how this king is still referred to in Thai history books. His descendant Vajiravudh (Rama VI) who had studied in England, realised that most Siamese kings' names were difficult to reproduce and remember for Westerners. He therefore disposed to use for all kings of

In 1767, Ayutthaya under King Ekkathat fell to Burmese invaders, the city was completely destroyed; burned and looted. Local warlords rose up to establish their supremacy in the absence of a central authority. Despite the fall of Ayutthaya, Taksin and his men in the same year managed to capture Chantaburi and Trat . During this time Phraya Ratchaburi became one of Taksin's six ministers and together with Phraya Pichai they were regarded by Taksin as his two most valuable generals. Swiftly Taksin made
