Cyclone Raja
Severe Tropical Cyclone Raja was a tropical cyclone that holds the 24-hour rainfall record of for the French Overseas Territory of Wallis and Futuna. The system was first noted by the Fiji Meteorological Service (FMS) as a weak tropical disturbance northeast of Tokelau in mid-December 1986. The system developed further as it moved southwest over the next few days, and it was classified as Tropical Cyclone Raja on 23 December. The newly named system slowed and unexpectedly recurved southeast towards the French territory of Wallis and Futuna on 24 December. Over the next two days, Raja interacted with what would become Severe Cyclone Sally and executed a tight loop, passing within of Futuna. The system peaked as a Category 3 severe tropical cyclone on 28 December, with estimated 10-minute sustained winds of . The storm turned southwest the next day and threatened Fiji, where it passed within of Vanua Levu and near (or over) several smaller islands in the Lau group during th ...

Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about . The most outlying island group is Ono-i-Lau. About 87% of the total population of live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts: either in the capital city of Suva; or in smaller urban centres such as Nadi—where tourism is the major local industry; or in Lautoka, where the Sugarcane, sugar-cane industry is dominant. The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geo ...

Polynesia
Polynesia () "many" and νῆσος () "island"), to, Polinisia; mi, Porinihia; haw, Polenekia; fj, Polinisia; sm, Polenisia; rar, Porinetia; ty, Pōrīnetia; tvl, Polenisia; tkl, Polenihia (, ) is a subregion of Oceania, made up of more than 1,000 islands scattered over the central and southern Pacific Ocean. The indigenous people who inhabit the islands of Polynesia are called Polynesians. They have many things in common, including language relatedness, cultural practices, and traditional beliefs. In centuries past, they had a strong shared tradition of sailing and using stars to navigate at night. The largest country in Polynesia is New Zealand. The term was first used in 1756 by the French writer Charles de Brosses, who originally applied it to all the islands of the Pacific. In 1831, Jules Dumont d'Urville proposed a narrower definition during a lecture at the Geographical Society of Paris. By tradition, the islands located in the southern Pacific have ...

Joint Typhoon Warning Centre
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] |
Nukufetau
Nukufetau is an atoll that is part of the nation of Tuvalu. The atoll was claimed by the US under the Guano Islands Act some time in the 19th century and was ceded in a treaty of friendship concluded in 1979 and coming into force in 1983. It has a population of 597 who live on Savave islet (2017 Census). In 1951 the school that was located on Motumua islet was transferred to Savave and became the government primary school for Nukufetau. It was named the Tutasi Memorial School in honour of its predecessor. Geography Nukufetau is an atoll with passages through the reef that allow large ships to enter and anchor in the lagoon. Nukufetau consists of at least 33 islets: * Faiava Lasi * Fale * Funaota * Kongo Loto Lafanga * Lafanga * Matanukulaelae * Motufetau * Motulalo * Motuloa (north of Nukufetau) * Motuloa (south of Nukufetau) * Motumua * Niualuka * Niuatui * Oua * Sakalua * Savave * Teafatule * Teafuaniua * Teafuanonu * Teafuone * Temotuloto * and at least 1 ...

Equator
The equator is a circle of latitude, about in circumference, that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Regional Specialised Meteorological Centre
A Regional Specialized Meteorological Centre (RSMC) is responsible for the distribution of information, advisories, and warnings regarding the specific program they have a part of, agreed by consensus at the World Meteorological Organization as part of the World Weather Watch. Environmental emergency response programme As a result of the poor communications between countries following the Chernobyl disaster in the Spring of 1986, the World Meteorological Organization (WMO) was requested by the International Atomic Energy Agency (IAEA) and other international organizations to arrange for early warning messages about nuclear accidents to be transmitted over the Global Telecommunications System (GTS). In addition some WMO member countries that lacked extensive forecasting capability requested that specialized pollutant transport and dispersion forecasts be provided during these emergencies. As a result, during 1989 Meteo-France (MF), Environment Canada (EC) and the United Kingdom's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Funafuti
Funafuti is the capital of the island nation of Tuvalu. It has a population of 6,320 people (2017 census), and so it has more people than the rest of Tuvalu combined, with approximately 60% of the population. It consists of a narrow sweep of land between wide, encircling a large lagoon (''Te Namo'') long and wide. The average depth of the Funafuti lagoon is about 20 fathoms (36.5 metres or 120 feet). With a surface area of , it is by far the largest lagoon in Tuvalu. The land area of the 33 islets around the atoll of Funafuti totals ; taken together, they constitute less than one percent of the total area of the atoll. Cargo ships can enter Funafuti's lagoon and dock at the port facilities on Fongafale. The capital of Tuvalu is sometimes said to be Fongafale or Vaiaku, but, officially, the entire atoll of Funafuti is its capital, since it has a single government that is responsible for the whole atoll. Fongafale The largest island is Fongafale. The island houses four villag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Depression
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Kanton Island
Canton Island (also known as Kanton or Abariringa), previously known as Mary Island, Mary Balcout's Island or Swallow Island, is the largest, northernmost, and , the sole inhabited island of the Phoenix Islands, in the Republic of Kiribati. It is an atoll located in the South Pacific Ocean roughly halfway between Hawaii and Fiji. The island is a narrow ribbon of land around a lagoon; an area of . Canton's closest neighbour is the uninhabited Enderbury Island, west-southwest. The capital of Kiribati, South Tarawa, lies to the west. , the population was 20, down from 61 in 2000. The island's sole village is called Tebaronga. Kiribati declared the Phoenix Islands Protected Area in 2006, with the park being expanded in 2008. The marine reserve contains eight coral atolls, including Canton. Because it is inhabited, management of Canton Island is described in the Canton Resource Use Sustainability Plan (KRUSP), which covers a radius around the atoll. Over 50% of the island and lag ...

Westerly Wind Burst
A westerly wind burst is a phenomenon commonly associated with El Niño events, whereby the typical east-to-west trade winds across the equatorial Pacific shift to west-to-east. A westerly wind burst is defined by Harrison and Vecchi (1997) as sustained winds of over a period of 5–20 days. However, no concrete definition has been determined, with Tziperman and Yu (2007) defining them as having winds of and lasting "at least a few days". On average, three of these events take place each year, but are significantly more common during El Niño years. They have been linked to various mesoscale phenomena, including tropical cyclones, mid-latitude cold surges, and the Madden–Julian oscillation. Their connection with Kelvin waves also indicate a connection with the onset of El Niño events, with every major occurrence since the 1950s featuring a westerly wind burst upon their onset. Recent studies, including Yu et al. (2003), have indicated some correlation between westerly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
