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 season's strongest tropical cyclone was Cyclone Asani, with maximum wind speeds of 100 km/h (65 mph) and a minimum barometric pressure of 982 hPa (29.00 inHg). 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 Ocea ...

Cyclone Sitrang
Cyclonic Storm Sitrang () was the first tropical cyclone to made landfall in Bangladesh since Mora in 2017. The second named storm of the relatively quiet 2022 North Indian Ocean cyclone season, Sitrang developed from an area of convection over the northern Andaman Sea on 18 October. The system tracked northwestward and slowly gaining strength. On 22 October, it was classified as a depression while located just west of the Andaman Islands. On the next day, the system intensified to Cyclonic Storm Sitrang and curved north-northeast. Sitrang strengthened slightly and attained peak intensity on 24 October, before making landfall in Barisal Division. The cyclone weakened quickly after landfall, and degenerated to a low-pressure area over northeastern Bangladesh. As Sitrang approached, ports of Bangladesh were put under warning signals. Ten million people were forced to evacuate in advance of the cyclone. Fisherman were urged to return from deep sea and anchored their boats. The gov ...

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 the 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 f ...

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] |
Strait Of Malacca
The Strait of Malacca is a narrow stretch of water, long and from wide, between the Malay Peninsula 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. Etymology The name "Malacca" is traditionally associated with the Malacca tree ('' Phyllanthus emblica''), also known as the Indian gooseberry tree, and is believed to derive from the local Malay word "Melaka". According to historical traditions, Parameswara, a Sumatran prince and the founder of the Malacca Sultanate, selected the site for his new kingdom where the city of Malacca now stands. It is said that he named the location "Melaka" after the Malacca tree under which he had rested. Over time, the name "Malacca" came to refer not only to the city but also to the strategically significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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, which refers to ''star of the sea'' or ''sea star''. Meteorological history In late May 2017, an area of convection began to organize in the Bay of Bengal. Favorable conditions, characterized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patuakhali
Patuakhali ( ''Potuakhali'') is a town and district headquarters of Patuakhali District located on the southern bank of Laukathi river in Barisal Division 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 the 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 first that settled in this region. Hi ...

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. The town has a low gradient with a shallow sand beach. It is a popular sea resort in India. In one of Warren Hastings' letters (1780 AD) to his wife, he referred to it as the'' 'Brighton of the East. History Digha historically known as ''Beerkul.'' 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 main gate of Old Digha. This place is also known as Alankarpur. A new mission has been developed in New Digha which is known as Sindhur Tara which is beside Amrabati Park.

Brown Ocean Effect
The brown ocean effect is an observed weather phenomenon involving some tropical cyclones after landfall. Normally, hurricanes and tropical storms lose strength when they make landfall, but when the brown ocean effect is in play, tropical cyclones maintain strength or even intensify over land surfaces. Australia is the most conducive environment for this effect, where such storm systems are called ''agukabams''. Background One source of the brown ocean effect has been identified as the large amount of latent heat that can be released from extremely wet soils. 2013 NASA studyfound that, from 1979-2008, 45 of 227 tropical storms either gained or maintained strength after making landfall. The press release stated, "The land essentially mimics the moisture-rich environment of the ocean, where the storm originated." Originally, research devoted to extratropical cyclones, storms that first derive energy from the warm ocean waters and later from the conjecture of various air masses, expl ...

1983 North Indian Ocean Cyclone Season
The 1983 North Indian Ocean cyclone season was the least active in 27 years. It was a below average season. A season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD. __TOC__ Systems Tropical Storm Aurora (1A) On August 9 a tropical depression developed in the northwest Arabian Sea ...
