1981 North Indian Ocean Cyclone Season
The 1981 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation. 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. Systems There were 12 depressions that developed during the season. The first formed on June 20 in the northern Bay of Bengal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
100th Meridian East
The meridian 100° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole. The 100th meridian east forms a great circle with the 80th meridian west. From Pole to Pole Starting at the North Pole and heading south to the South Pole The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface.

1981–82 South-West Indian Ocean Cyclone Season
The 1981–82 South-West Indian Ocean cyclone season was a destructive and deadly cyclone season that occurred in Madagascar, where four cyclones killed 100 people and caused $250 million (USD) in damage. The season was fairly active, lasting from October to May. There were nine named storms that attained gale-force winds, or at least . Five of the storms attained tropical cyclone status, which have 10-minute sustained winds of at least . The first storm was Tropical Cyclone Alex, which was named by the Australian Bureau of Meteorology (BoM). this was due to the boundary of the basin at the time, which incorporated the Indian Ocean south of the equator and extended from the east coast of Africa to 80° E; the eastern extent was later moved to 90° E. Two other storms – Armelle and Damia – also originated in the Australian basin. The latter was the strongest cyclone on record in the basin at the time by barometric pressure, estimated at .

1981–82 South Pacific Cyclone Season
The 1981–82 South Pacific cyclone season was a slightly-below average South Pacific tropical cyclone season, with 6 tropical cyclones occurring within the South Pacific Ocean basin between 160°E and 120°W during the season. After this season, the names Gyan and Isaac were retired from the lists of names, after they caused significant impacts to South Pacific island nations. During the season, tropical cyclones were monitored by the Tropical Cyclone Warning Centers in Nadi, Fiji, Brisbane, Australia and Wellington, New Zealand. During the season TCWC Nadi issued warnings and assigned names to any tropical cyclones that developed between the Equator and 25°S while TCWC Wellington issued warnings for any that were located to the south of 25°S. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC), also monitored the basin and issued unofficial warnings for American interests.

1980–81 Australian Region Cyclone Season
The 1980–81 Australian region cyclone season was an above average tropical cyclone season. It officially started on 1 November 1980 and officially ended on 30 April 1981. Systems Severe Tropical Cyclone Alice–Adelaide Formed on 3 November, just south of Selat Mentawai then moved southwestward before reaching a peak intensity of and a minimum pressure of on 8 November. On 12 November the storm began to move northwestward and two days later dissipated over the open Indian Ocean. Severe Tropical Cyclone Bert–Christelle The origins of Cyclone Bert–Christelle can be traced to a quasistationary convergence zone that spread across Indonesia to north of the Cocos Islands. Bert–Christelle was slow to organize but began to show signs of organization on November 26. Later on that day, the disturbance gained sufficient organization, noted by curved cloudbands, to be classified as Cyclone Bert.

1981 Pacific Typhoon Season
The 1981 Pacific typhoon season was a slightly above average season that produced 29 tropical storms, 13 typhoons and two intense typhoons. The season ran throughout 1981, though most tropical cyclones typically tropical cyclogenesis, develop between May and November. The season's first named storm, Freda, developed on March 12 while the final storm, Typhoon Lee (1981), Lee, dissipated on December 29. Tropical cyclones only accounted for 12 percent of the rainfall in Hong Kong this season, the lowest percentage for the protectorate since 1972.Hong Kong Royal Observatory (1982)Meteorological Results 1981: Part III - Tropical Cyclone Summaries.

1981 Pacific Hurricane Season
The 1981 Pacific hurricane season was a slightly below average Pacific hurricane season. The season officially started on May 15 in the eastern Pacific basin and June 1 in the central Pacific basin. Both basins' seasons ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone of the season was designated on May 30, and the final storm of the season, Hurricane Otis, dissipated on October 30. The season produced fifteen named storms and a total of eight hurricanes, which was near normal. However, the total of one major hurricane was below the average of three. The strongest tropical cyclone of the season was Hurricane Norma, which was a powerful Category 3 hurricane on the Saffir–Simpson Hurricane Scale. The storm caused six deaths – five in Texas, and one in Mexico, due to severe flooding. Additionally, the storm caused $74 million (equivalent to $&nb ...

1981 Atlantic Hurricane Season
The 1981 Atlantic hurricane season featured direct or indirect impacts from nearly all of its 12 Tropical cyclone naming, tropical or subtropical storms. Overall, the season was fairly active, with 22 tropical depressions, 12 of which became named storms. 7 of those reached hurricane status and a further 3 intensified into major hurricanes. The season officially began on June 1, 1981, and lasted until November 30, 1981. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, tropical cyclogenesis can occur before these dates, as demonstrated with the development of two tropical depressions in April and Tropical Storm Arlene in May. At least one tropical cyclone formed in each month between April and November, with the final system, Subtropical Storm Three, becoming Extratropical cyclone, extratropical on November 17, 1981.

North Indian Ocean Tropical Cyclone
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 ...
