1962–63 South-West Indian Ocean Cyclone Season
The 1962–63 South-West Indian Ocean cyclone season was an average cyclone season, although it began early with the first October storm since 1911. Two storms formed in December, both of them passing near the Mascarene Islands. Systems Moderate Tropical Storm Amy Toward the beginning of October, an area of low pressure persisted near Diego Garcia, while a strong anticyclone stretched from Madagascar to Île Amsterdam. On October 9, Diego Garcia reported westerly winds and falling pressure, indicating that a tropical cyclone developed that day. This marked the first October tropical storm formation in the basin since 1911. Given the name Amy, the storm moved to the west-southwest, tracked by Television Infrared Observation Satellite (TIROS). Gradual intensification occurred, aided by the anticyclone to the south, and Amy reached peak winds of around 75 km/h (45 mph) on October 10. Passing north of Rodrigues island, the storm's track shifted more westerly as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1960–61 South-West Indian Ocean Cyclone Season
The 1960–61 South-West Indian Ocean cyclone season was one of the least active South-West Indian Ocean cyclone seasons on record. It only had 6 tropical depressions, 5 named storms, 4 tropical storms, and 1 cyclone, Doris. Additionally, none of its storms made landfall, therefore it had almost no deaths or damage. The season was also the second with named storms, the first being 1959–60. Systems Tropical Storm Anna Ana existed from November 11 to November 14. Its peak intensity was 65 kilometers an hour, or 40 miles per hour, in 1-minute maximum sustained winds. Unnamed tropical depression A tropical depression briefly existed in the northeast portion of the basin from November 29–30. Its peak intensity is currently unknown. Tropical Storm Barbara Barbara existed from November 27 to December 3. In 1-minute maximum sustained winds, its peak intensity was 85 miles per hour. That is equal to 50 kilometers per hour. For its whole duration, it stayed away from lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intertropical Convergence Zone
The Intertropical Convergence Zone (ITCZ ), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies seasonally. When it lies near the geographic Equator, it is called the near-equatorial trough. Where the ITCZ is drawn into and merges with a monsoonal circulation, it is sometimes referred to as a monsoon trough, a usage that is more common in Australia and parts of Asia. Meteorology The ITCZ was originally identified from the 1920s to the 1940s as the ''Intertropical Front'' (''ITF''), but after the recognition in the 1940s and the 1950s of the significance of wind field convergence in tropical weather production, the term ''Intertropical Convergence Zone'' (''ITCZ'') was then applied. The ITCZ appears as a band of clouds, usually thunderstorms, that encircle the globe near the Equator. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1962 Pacific Typhoon Season
The 1962 Pacific typhoon season had no official bounds; there was activity in every month but January, March, and June, but most tropical cyclones form in the northwestern Pacific Ocean between May and November and this conventionally delimits the season. The majority of the Pacific typhoons in 1962 formed in the Pacific Ocean north of the equator and west of the International Date Line with two exceptions: Tropical Depressions Fifty and Sixty-three formed in the Central Pacific. All tropical depressions are assigned a number. Most systems reaching tropical storm strength were assigned a name; all typhoons were named. Season activity Ninety tropical waves formed in the 1962 season. Only 78 of these became major easterly waves. 38 of these waves became tropical depressions, 30 became storms and 23 become typhoons. This record of 24 typhoons beat 1952 record which had 21. This record was beaten in the 1964 season with 26 typhoons. Six super typhoons formed in 1962 which were Geor ...

1963 Pacific Hurricane Season
The 1963 Pacific hurricane season was a below-average season, with 8 storms and 4 hurricanes forming. The season ran through the summer and fall of 1963. The strongest of these storms were Glenda and Mona, which both had winds. The first storm, Emily, made landfall near Manzanillo, Mexico as a Category 1 hurricane. The next hurricanes, Florence and Glenda, stayed far away from land. Jennifer-Katherine made landfall on Baja California as a tropical depression on September 18. Tropical Storm Irah affected Hawaii as a tropical depression. An unnamed tropical storm curved round Hawaii from 2–8 August. Lillian became post-tropical shortly before making landfall on September 29 with winds of 50 mph. Mona, the final storm of the season made landfall around about the same area as Lillian did with winds of 85 mph. __TOC__ Systems Timeline of activity in the 1963 Pacific hurricane season ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend ...

1962 Pacific Hurricane Season
The 1962 Pacific hurricane season was a moderately active Pacific hurricane season that included two hurricane landfalls. The 1962 Pacific hurricane season officially started on May 15, 1962 in the eastern Pacific and June 1, 1962 in the Central Pacific Hurricane Center's area of responsibility and lasted until November 30, 1962 in both regions. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The first of two hurricane landfalls, Hurricane Valerie, struck northwestern Mexico in June. The other, Hurricane Doreen, hit further to the north of Valerie in October. The most impacting storm of the season was Tropical Storm Claudia, after its remnants dropped heavy rainfall in portions of Arizona. The rainfall left damaging flooding across rivers and towns. No people were killed, but damage totaled to $11 million (1962 USD). Moreover, Tropical Storm Bernie also made landfall along the Baja Calif ...

1963 Atlantic Hurricane Season
The 1963 Atlantic hurricane season featured one of the deadliest tropical cyclones on record in the Atlantic hurricane season, Atlantic basin: Hurricane Flora. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was a slightly below average season in terms of tropical storms, with a total of ten nameable storms. The first system, an unnamed tropical storm, developed over the Bahamas on June 1. In late July, Hurricane Arlene (1963), Hurricane Arlene, developed between Cape Verde and the Lesser Antilles. The storm later impacted Bermuda, where strong winds resulted in about $300,000 (1963 United States dollar, USD) in damage. Other storms such as hurricanes Beulah and Debra, as well as an unnamed tropical storm, did not impact land. During the month of September, Tropical Storm Cindy (1963), Tropical Storm Cindy caused wind damag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1962 Atlantic Hurricane Season
The 1962 Atlantic hurricane season featured Hurricane Daisy (1962), Hurricanes Daisy and Hurricane Ella (1962), Ella – two tropical cyclones that showed the latest dates for the fourth and fifth named storms on record since tropical cyclones were first named in the North Atlantic ocean, starting in 1950, when they both formed on September 29 and October 14. On the same hand, it was the least active since 1939 Atlantic hurricane season, 1939, with only five tropical cyclone naming, named storms. Although the season officially began on June 15, the first named storm did not form until August 26, the third-latest date. Hurricane Alma brushed the Outer Banks before becoming extratropical southeast of New England, destroying hundreds of boats and producing beneficial rainfall. In late August, Tropical Storm Becky developed unusually far east in the Atlantic Ocean, becoming the easternmost storm on record to recurve to the northeast. Celia followed in the September, forming e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mozambique Channel
The Mozambique Channel (french: Canal du Mozambique, mg, Lakandranon'i Mozambika, pt, Canal de Moçambique) is an arm of the Indian Ocean located between the Southeast African countries of Madagascar and Mozambique. The channel is about long and across at its narrowest point, and reaches a depth of about off the coast of Mozambique. A warm current, the Mozambique Current, flows in a southward direction in the channel, leading into the Agulhas Current off the east coast of Southern Africa. Extent The International Hydrographic Organization (IHO) defines the limits of the Mozambique Channel as follows: ::''On the North.'' A line from the estuary of the River Rovuma () to Ras Habu, the northernmost point of Ile Grande Comore, the northernmost of the Comore (Comoro) Islands, to Cap d'Ambre (Cape Amber), the northern extremity of Madagascar (). ::''On the East.'' The west coast of Madagascar. ::''On the South.'' A line from Cap Sainte-Marie, the southern extremity of Mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term " cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. They are term ...

Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar Low
A polar low is a mesoscale, short-lived atmospheric low pressure area, low pressure system (depression) that is found over the ocean areas poleward of the main polar front in both the Northern and Southern Hemispheres, as well as the Sea of Japan. The systems usually have a horizontal length scale of less than and exist for no more than a couple of days. They are part of the larger class of mesoscale meteorology, mesoscale weather systems. Polar lows can be difficult to detect using conventional weather reports and are a hazard to high-latitude operations, such as shipping and gas and oil platforms. Polar lows have been referred to by many other terms, such as polar mesoscale vortex, Arctic hurricane, Arctic low, and cold air depression. Today the term is usually reserved for the more vigorous systems that have near-surface winds of at least 17 m/s (38 mph). History Polar lows were first identified on the meteorological satellite imagery that became available in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hail
Hail is a form of solid precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures. Unlike other forms of water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and translucent), and snow (which consists of tiny, delicately crystalline flakes or needles), hailstones usually measure between and in diameter. The METAR reporting code for hail or greater is GR, while smaller hailstones and graupel are coded GS. Hail is possible within most thunderstorms (as it is produced by cumulonimbus), as well as within of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderstorm (similar to tornadoes) and lowered heights of the freezing l ...
