Cyclone Phethai
Severe Cyclonic Storm Phethai was a tropical cyclone which affected some portions of Sri Lanka and India during December 2018. The fourteenth depression, ninth deep depression, seventh cyclonic storm, and fifth severe cyclonic storm of the 2018 North Indian Ocean cyclone season, Phethai developed from an area of low pressure that formed over the Bay of Bengal on December 13. Having forecasted not to develop significantly, the depression then strengthened to a deep depression later that day before becoming a cyclonic storm on December 15. Phethai further intensified and peaked to a severe cyclonic storm, the following day. The system then steadily weakened due to land interaction and increasing wind shear, before making landfall as a disorganized system over Andhra Pradesh on December 17. It degenerated to an area of low-pressure inland, the next day. Phethai caused over eight fatalities during its path towards East India. Some rice crops and paddies were destroyed and flooded, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka

Anticyclone
An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone). Effects of surface-based anticyclones include clearing skies as well as cooler, drier air. Fog can also form overnight within a region of higher pressure. Mid-tropospheric systems, such as the subtropical ridge, deflect tropical cyclones around their periphery and cause a temperature inversion inhibiting free convection near their center, building up surface-based haze under their base. Anticyclones aloft can form within warm-core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large-scale sinking such as a subtropical ridge. The evolution of an anticyclone depends upon variables such as its size, intensity, and extent of moist con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Coast Guard
The Indian Coast Guard (ICG) is a maritime law enforcement and search and rescue agency of India with jurisdiction over its territorial waters including its contiguous zone and exclusive economic zone. The Indian Coast Guard was formally established on 1 February 1977 by the ''Coast Guard Act, 1978'' of the Parliament of India. It operates under the Ministry of Defence. The Coast Guard works in close cooperation with the Indian Navy, the Department of Fisheries, the Department of Revenue (Customs), and the Central Armed Police Forces, and the State Police Services. History The establishment of the Indian Coast Guard was first proposed by the Indian Navy to provide non-military maritime services to the nation. In the 1960s, sea-borne smuggling of goods was threatening India's domestic economy. The Indian Customs Department frequently called upon the Indian Navy for assistance with patrol and interception in the anti-smuggling effort. The Nagchaudhuri Committee was constit ...

National Disaster Response Force
The National Disaster Response Force (NDRF) is an Indian specialized force constituted "for the purpose of special response to a threatening disaster situation or disaster" under the Disaster Management Act, 2005. The "Apex Body for Disaster Management" in India is the National Disaster Management Authority (India), National Disaster Management Authority (NDMA). The Chairman of the NDMA is the Prime Minister. The responsibility of managing disasters in India is that of the State Government. The ‘Nodal Ministry’ in the central government for management of natural disasters is the Ministry of Home Affairs (MHA). When 'calamities of severe nature' occur, the Central Government is responsible for providing aid and assistance to the affected state, including deploying, at the State's request, of Armed Forces, Central Paramilitary Forces, National Disaster Response Force (NDRF), and such communication, air and other assets, as are available and needed.

Cyclone Phethai During Its Landfall Near Kakinada
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within smaller mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process of cyclone formation and ...

Cyclone Gaja
Very Severe Cyclonic Storm Gaja was the sixth named cyclone of the 2018 North Indian Ocean cyclone season, after Cyclones Sagar, Mekunu, Daye, Luban, and Titli. Forming on November 5 as a low-pressure system over the Gulf of Thailand, the system crossed through Southern Thailand and the Malay Peninsula and eventually crossed into the Andaman Sea. The weak system intensified into a depression over the Bay of Bengal on November 10 and further intensified to a cyclonic storm on November 11, being named ''Gaja''. After tracking west-southwestward for a number of days in the Bay of Bengal, Gaja made landfall in South India on November 16, moved westward through Vedaranyam, Thiruthuraipoondi,Mannargudi, Muthupet, Pudukkottai, Adirampattinam, Pattukkottai, and Peravurani. The storm survived its crossing into the Arabian Sea; however, it degenerated into a remnant low in hostile conditions only a few days later, before dissipating early on November 22. 45 people were killed by the sto ...

Cyclonic Storm Daye (2018)
The 2018 North Indian Ocean cyclone season was one of the most active North Indian Ocean cyclone seasons since 1992, with the formation of fourteen depressions and seven cyclones. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ''ARB'' by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated ''BOB'' by the IMD. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Wa ...

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
InHg
Inch of mercury (inHg and ″Hg) is a non- SI unit of measurement for pressure. It is used for barometric pressure in weather reports, refrigeration and aviation in the United States. It is the pressure exerted by a column of mercury in height at the standard acceleration of gravity. Conversion to metric units depends on the temperature of mercury, and hence its density; typical conversion factors are: In older literature, an "inch of mercury" is based on the height of a column of mercury at .Barry N.
