North Indian Ocean Tropical Cyclone Season
In the Indian Ocean north of the equator, tropical cyclones can form throughout the year on either side of the Indian subcontinent, although most frequently between April and June, and between October and December. The North Indian Ocean is the least active official basin, contributing only seven percent of the world's tropical cyclones. However the basin has produced some of the deadliest cyclones in the world, since they strike over very densely populated areas. The Regional Specialized Meteorological Centre (RSMC) is the India Meteorological Department (IMD) and it is responsible to monitor the basin, issues warning and name the storms. Sub-basins The basin is divided into two sub-basins the Bay of Bengal and the Arabian Sea. The Bay of Bengal, located in the northeast of the Indian Ocean. The basin is abbreviated ''BOB'' by the India Meteorological Department (IMD). The United States's Joint Typhoon Warning Center unofficially designates as ''B'' to classify storms form ...

North Indian Cyclone Tracks 1970-2005
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek ''boreas'' "north wind, north" which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oman
Oman, officially the Sultanate of Oman, is a country located on the southeastern coast of the Arabian Peninsula in West Asia and the Middle East. It shares land borders with Saudi Arabia, the United Arab Emirates, and Yemen. Oman’s coastline faces the Arabian Sea to the southeast and the Gulf of Oman on the northeast. The exclaves of Madha and Musandam Governorate, Musandam are surrounded by the United Arab Emirates on their land borders, while Musandam’s coastal boundaries are formed by the Strait of Hormuz and the Gulf of Oman.

Cyclogenesis
Cyclogenesis is the development or strengthening of Cyclonic rotation, cyclonic circulation in the atmosphere (a low-pressure area). Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone, and at any size from the microscale meteorology, microscale to the synoptic scale meteorology, synoptic scale. * Tropical cyclones form due to latent heat driven by significant thunderstorm activity, developing a warm core. * Extratropical cyclones form as waves along weather fronts before occluding later in their life cycle as cold core cyclones. * Mesocyclones form as warm core cyclones over land, and can lead to tornado formation. Waterspouts can also form from mesocyclones, but more often develop from environments of high instability and low vertical wind shear. The process in which an extratropical cyclone undergoes a rapid drop in atmospheric pressure (24 millibars or more) in a 24-hour period is referred to a ...

Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation (meteorology), precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 8 g of water per cubic metre of air at , and 28 g of water per cubic metre of air at Three primary measurements of humidity are widely employed: abso ...

South China Sea
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by South China, in the west by the Indochinese Peninsula, in the east by the islands of Taiwan island, Taiwan and northwestern Philippines (mainly Luzon, Mindoro and Palawan Island, Palawan), and in the south by Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around . It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan, the Java Sea via the Karimata Strait, Karimata and Bangka Straits and directly with Gulf of Thailand. The Gulf of Tonkin is part of the South China Sea. $3.4 trillion of the world's $16 trillion Maritime transport, maritime shipping passed through South China Sea in 2016. Oil and natural gas reserves have been found in the area. The Western Central Pacific accounted for 14% of world's commercial fishing in 2010. The South China Sea Islands, ...

Typhoon
A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least . This region is referred to as the Northwestern Pacific Basin, accounting for almost one third of the world's tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centres for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form througho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andaman Sea
The Andaman Sea (historically also known as the Burma Sea) is a marginal sea of the northeastern Indian Ocean bounded by the coastlines of Myanmar and Thailand along the Gulf of Martaban and the west side of the Malay Peninsula, and separated from the Bay of Bengal to its west by the Andaman Islands and the Nicobar Islands. Its southern end is at Breueh Island just north of Sumatra, with the Strait of Malacca further southeast. Traditionally, the sea has been used for fishery and transportation of goods between the coastal countries and its coral reefs and islands, which are popular tourist destinations. The fishery and tourist infrastructure was severely damaged by the December 2004 Indian Ocean earthquake and tsunami. Geography Location The Andaman Sea, which extends over 92°E to 100°E and 4°N to 20°N, occupies a very significant position in the Indian Ocean, yet remained unexplored for a long period. To the south of Myanmar, west of Thailand, and north of Indonesia, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Onil
Severe Cyclonic Storm Onil was the first tropical cyclone to be named in the northern Indian Ocean. Forming out of an area of convection several hundred kilometres southwest of India on October 1 2004, Cyclone Onil quickly attained its peak intensity on October 2 with winds of and a barometric pressure of 990 mbar (hPa; ). However, dry air quickly entered the system, causing it to rapidly weaken to a depression just off the coast of Gujarat, India. Over the following several days, the system took a slow, erratic track towards the south-southeast. After turning northeastward, the system made landfall near Porbandar on October 10 and dissipated shortly thereafter. Throughout southeastern Pakistan and northwestern India, thousands of residents were evacuated prior to the cyclone's arrival. In these areas, the storm produced moderate to heavy rainfall, peaking at in Thatta, Sindh, Pakistan. These rains led to flash flooding in several areas. Nine people died in seve ...

Henry Piddington
Henry Piddington (7 January 1797 – 7 April 1858) was an English sea captain who sailed in East India and China and later settled in Bengal where he worked as a curator of a geological museum and worked on scientific problems, and is particularly well known for his pioneering studies in meteorology of tropical storms and hurricanes. He noted the circular winds around a calm centre recorded by ships caught in storms and coined the name ''cyclone'' in 1848. Scientific pursuits Henry Piddington was the third of eight (excluding a ninth child who died at infancy) children born to an innkeeper at Lewes, James John Piddington (1757–1837) and his wife, Elizabeth Ann (1762–1835). The family moved to Uckfield in 1802–03 where the Henry would have encountered travelling sailors at the inn where his father worked. Little is known of his early sailing life but he rose to command a ship and by 1824 he was living in Bengal and settled in Calcutta (city in India) around 1831 and took an ...

Cyclone Gonu
Super Cyclonic Storm Gonu was an extremely powerful tropical cyclone that became the strongest cyclone on record in the Arabian Sea. The second named tropical cyclone of the 2007 North Indian Ocean cyclone season, Gonu developed from a persistent area of convection in the eastern Arabian Sea on June 1, 2007. With a favorable upper-level environment and warm sea surface temperatures, it rapidly intensified to attain peak winds of on June 4, according to the India Meteorological Department. Gonu weakened after encountering dry air and cooler waters, and early on June 6, it made landfall on the easternmost tip of Oman, becoming the strongest tropical cyclone to hit the Arabian Peninsula. It then turned northward into the Gulf of Oman, and dissipated on June 7, after making landfall in southern Iran, the first landfall in the country since 1898. Intense tropical cyclones like Gonu are extremely rare in the Arabian Sea, and most storms in this area tend to be small and dissip ...

Monsoons
A monsoon () 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 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 the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
