Cyclone Mocha
Extremely Severe Cyclonic Storm Mocha () was a powerful and deadly tropical cyclone in the North Indian Ocean which affected Myanmar and parts of Bangladesh in May 2023. The second depression and the first cyclonic storm of the 2023 North Indian Ocean cyclone season, Mocha originated from a low-pressure area that was first noted by the India Meteorological Department (IMD) on 8 May. After consolidating into a depression, the storm tracked slowly north-northwestward over the Bay of Bengal, and reached extremely severe cyclonic storm intensity. After undergoing an eyewall replacement cycle, Mocha rapidly strengthened, peaking at Category 5-equivalent intensity on 14 May with winds of , tying with Cyclone Fani as the strongest storm on record in the North Indian Ocean in terms of 1-minute sustained winds. Mocha slightly weakened before making landfall, and its conditions quickly became unfavorable. Mocha rapidly weakened once inland and dissipated shortly thereafter. Thousan ...

Andaman And Nicobar Islands
The Andaman and Nicobar Islands is a union territory of India consisting of 572 islands, of which 37 are inhabited, at the junction of the Bay of Bengal and the Andaman Sea. The territory is about north of Aceh in Indonesia and separated from Thailand and Myanmar by the Andaman Sea. It comprises two island groups, the Andaman Islands (partly) and the Nicobar Islands, separated by the 150 km (100 mile) wide Ten Degree Channel (on the 10°N parallel), with the Andaman islands to the north of this latitude, and the Nicobar islands to the south (or by 179 km; 111 miles). The Andaman Sea lies to the east and the Bay of Bengal to the west. The island chains are thought to be a submerged extension of the Arakan Mountains. The territory's capital is the city of Port Blair. The total land area of the islands is approximately . The territory is divided into three districts: the Nicobar District with Car Nicobar as its capital, the South Andaman district with Port Bl ...

Sittwe
Sittwe (; ; formerly Akyab) is the capital of Rakhine State, Myanmar (Burma). Sittwe, pronounced ''sait-tway'' in the Rakhine language, is located on an estuarial island created at the confluence of the Kaladan, Mayu, and Lay Mro rivers emptying into the Bay of Bengal. As of 2006 the city has 181,000 inhabitants. It is the administrative seat of Sittwe Township and Sittwe District. Etymology The name Sittwe, which literally means "the place where the war meets," is derived from the Burmese pronunciation of စစ်တွေ (pronounced ''Saittwe'' in Arakanese language). When the Burmese King Bodawpaya invaded the Mrauk U Kingdom in 1784, the Rakhine defenders encountered the Burmese force at the mouth of Kaladan river. In the ensuing battle, which was waged on both land and water, the Mrauk U forces were defeated. The place where the battle occurred came to be called ''Saittwe'' by the Rakhine, and colloquially as ''Sittwe'' by the Burmese. In early 1825, during the ...

Atmospheric Convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Overview There are a few general archetypes of atmospheric instability that are used to explain convection (or lack thereof). A necessary (but not sufficient) condition for convection is that the environmental lapse rate (the rate of decrease of temperature with height) is steeper than the lapse rate experienced by a rising parcel of air. When this condition is met, upward-displaced air parcels can become buoyant and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Typhoon Warning Center
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. Their warnings are intended for the protection of primarily military ships and aircraft as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time the center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-pressure Area
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis force, Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the Atmosphere of Earth, atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In Meteorology#Dynamic meteorology, meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper Trough (meteorology), troughs, which form half of a Rossby wave within the Westerlies (a trough (meteorology), trough with l ...

Convergence Zone
A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation. Large-scale convergence, called synoptic-scale convergence, is associated with weather systems such as baroclinic troughs, low-pressure areas, and cyclones. The large-scale convergence zone formed over the equator, the Intertropical Convergence Zone, has condensed and intensified as a result of the global increase in temperature. Small-scale convergence will give phenomena from isolated cumulus clouds to large areas of thunderstorms. The inverse of convergence is divergence. Large scale An example of a convergence zone is the Intertropical Convergence Zone (ITCZ), a low pressure area which girdles the Earth at the Equator.Waliser, D.E.; Jiang, X. (2015).

2022–23 South-West Indian Ocean Cyclone Season
The 2022–23 South-West Indian Ocean cyclone season is an ongoing event of the annual cycle of tropical cyclone and subtropical cyclone formation. It began on 15 November 2022, and will end on 30 April 2023, with the exception for Mauritius and the Seychelles, for which it will end on 15 May 2023. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of 90°E and south of the Equator. However, tropical cyclones can form year-round, and all tropical cyclones that will form between 1 July 2022 and 30 June 2023 will be part of the season. Tropical and subtropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion and unofficially by the Joint Typhoon Warning Center. __TOC__ Seasonal forecasts In October 2022, Météo-France issued its seasonal forecast of cyclone activity for the basin. The MFR predicted a season that was slightly below average to aver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madden–Julian Oscillation
The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30- to 90-day) variability in the tropical atmosphere. It was discovered in 1971 by Roland Madden and Paul Julian of the American National Center for Atmospheric Research (NCAR). It is a large-scale coupling between atmospheric circulation and tropical deep atmospheric convection. Unlike a standing pattern like the El Niño–Southern Oscillation (ENSO), the Madden–Julian oscillation is a traveling pattern that propagates eastward, at approximately , through the atmosphere above the warm parts of the Indian and Pacific oceans. This overall circulation pattern manifests itself most clearly as anomalous rainfall. The Madden–Julian oscillation is characterized by an eastward progression of large regions of both enhanced and suppressed tropical rainfall, observed mainly over the Indian and Pacific Ocean. The anomalous rainfall is usually first evident over the western Indian Ocean, and remains e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Unity Government Of Myanmar
The National Unity Government of the Republic of the Union of Myanmar ( my, အမျိုးသားညီညွတ်ရေး အစိုးရ; abbreviated NUG) is a Myanmar government in exile formed by the Committee Representing Pyidaungsu Hluttaw (CRPH), a group of elected lawmakers and members of parliament ousted in the 2021 Myanmar coup d'état. The European Parliament has recognized the NUG as the legitimate government of Myanmar. It includes representatives of the National League for Democracy (the deposed ruling party of former state counsellor Aung San Suu Kyi), ethnic minority insurgent groups, and various minor parties. The State Administration Council—the country's ruling military junta—has declared the NUG illegal and a terrorist organization. In May 2021, the NUG announced the formation of a "People's Defense Force", and in September the launch of a "defensive war" and nation-wide revolution against the military junta. As of September 2021, the NUG h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
