2022 North Indian Ocean Cyclone Season
The 2022 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was an above-average season in terms of depressions and average in terms of deep depressions, but slightly below-average in terms of cyclonic storms. It was also the least deadly North Indian Ocean cyclone season since 1988, according to official data. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the peak from May to 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 eas ...

Cyclone Asani
Severe Cyclonic Storm Asani () was a strong tropical cyclone that made landfall in India in May 2022. It was the strongest storm of 2022 North Indian Ocean cyclone season. The third depression and deep depression, and the first named storm of the 2022 North Indian Ocean cyclone season, Asani originated from a depression that the Indian Meteorological Department first monitored on May 7. Conditions rapidly favored development as the system became a deep depression by that day before intensifying to a Cyclonic Storm Asani. On the next day it further intensified and peak to a severe cyclonic storm, before making landfall as a deep depression system over Andhra Pradesh. It degenerated into a well marked low-pressure on May 12. Meteorological history During the first week of May, a strong pulse of Madden-Julian Oscillation (MJO) and Equatorial Rossby wave (ERW) prevailed in this basin. These two conditions led to a formation, of a cyclonic circulation, over the southern Andaman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclones Mandous And ARB 03
Severe Cyclonic Storm Mandous was the third cyclonic storm, as well as the third most intense tropical cyclone of the 2022 North Indian Ocean cyclone season. The remnants of the system later regenerated into Deep Depression ARB 03 in the Arabian Sea. The system struck the Andaman and Nicobar Islands, as well as South India. Meteorological history The Indian Meteorological Department issued a bulletin stating that a tropical depression had formed in the Bay of Bengal and was designated ''BOB 09''. The JTWC, released a TCFA on the system, stating that it could intensify further, because of very warm waters and low to moderate wind shear, designating it ''Invest 96B''. A day later, both the JTWC and IMD classified this low pressure as a "cyclonic storm" and it was named ''Mandous''. Mandous continued tracking westward, and later, attaining wind speeds of , strengthened into a Severe Cyclonic Storm. As it continued tracking westward, land interaction caused in to fall to Cyclonic St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclogenesis
Cyclogenesis is the development or strengthening of 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 to the 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 as explosive cyclogenesis, and is usually present during the formation ...

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 evi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vortex
In fluid dynamics, a vortex ( : vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil. Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterise vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis. In the absence of external forces, viscous friction within the fluid tends to organise the flow into a collection of irrotational vortices, possibly superimposed to larger-scale flows, including larger-scale vortices. Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclone
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 ...

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 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 are popular tourist destinations. The fishery and tourist infrastructure was severely damaged by the 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 long period of time. To the south of Myanmar, west of Thailand, and north of Indonesia, this sea is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strait Of Malacca
The Strait of Malacca is a narrow stretch of water, 500 mi (800 km) long and from 40 to 155 mi (65–250 km) wide, between the Malay Peninsula (Peninsular Malaysia) to the northeast and the Indonesian island of Sumatra to the southwest, connecting the Andaman Sea (Indian Ocean) and the South China Sea (Pacific Ocean). As the main shipping channel between the Indian and Pacific oceans, it is one of the most important shipping lanes in the world. It is named after the Malacca Sultanate that ruled over the strait between 1400 and 1511, the center of administration of which was located in the modern-day state of Malacca, Malaysia. Extent The International Hydrographic Organization define the limits of the Strait of Malacca as follows: History Early traders from Arabia, Africa, Persia, and Southern India reached Kedah before arriving at Guangzhou. Kedah served as a western port on the Malay Peninsula. They traded glassware, camphor, cotton goods, brocades, ivory, sandalwood, ...

Cyclone Mora
Severe Cyclonic Storm Mora was a moderate but deadly tropical cyclone that caused widespread devastation and severe flooding in Sri Lanka, Andaman and Nicobar Islands, Bangladesh, Myanmar and Northeast India in May 2017. The second named storm of the 2017 2017 North Indian Ocean cyclone season, annual cyclone season, Mora developed from an area of low pressure over the southeastern Bay of Bengal on May 28. Mora reached peak strength with maximum sustained winds of . The cyclone made landfall near Chittagong on the morning of May 30 and steadily weakened, dissipating early in the morning on May 31. Across its path, Mora dropped a large amount of rain, including 225mm of rainfall in Chittagong and northeast India. The storm is estimated to have caused damages nearing US$300 million. The name ''Mora'', suggested by Thailand, means agate. Meteorological history In late May 2017, an area of convection (meteorology), convection began to organize in the Bay of Bengal.

Patuakhali
Patuakhali ( bn, পটুয়াখালী ''Potuakhali'') is a town and district headquarter of Patuakhali District located on the southern bank of Laukathi river in the division of Barisal in Bangladesh. It is the administrative headquarter of Patuakhali district and one of the oldest towns and municipalities in the country. Patuakhali municipality was established in 1892. The town covers an area of 27.03 km2 with a population of 65,000 according to 2011 census. Title There are different opinions about the origin of the name "Patuakhali". The general belief is that the name is derived from Bengali name "Patuar Khal" (Canal of Patua) which flows down the present Patuakhali municipality connecting the Bay of Bengal. It is said that at the beginning of the 17th century the Portuguese pirates used to make regular incursions to this area through this canal. The local people named it "Patuar Khal" which is now called "Patuakhali. Austric origin people are probably the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digha
Digha is a seaside resort town in the state of West Bengal, India. It lies in Purba Medinipur district and at the northern end of the Bay of Bengal. It has a low gradient with a shallow sand beach. It is a popular sea resort in West Bengal. History Originally, there was a place called ''Beerkul'', where Digha lies today. This name was referred in Warren Hastings's letters (1780) as Brighton of the East. An English businessman John Frank Snaith started living here in 1923 and his writings provided a good exposure to this place. He convinced West Bengal Chief Minister Bidhan Chandra Roy to develop this place to be a beach resort. An old church can be seen near the Old Digha Main gate. This place is also known as Alankarpur Digha. A new mission has been developed in New Digha which is known as Sindhur Tara which is beside Amrabati Park its a Church where it is possible to wish for the welfare of family and loved ones. The best way to visit is to book a local van rickshaw. There a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
