Cyclone Anne
Severe Tropical Cyclone Anne was one of the most intense tropical cyclones within the South Pacific basin during the 1980s. The cyclone was first noted on January 5, 1988 as a weak tropical depression to the northeast of Tuvalu, in conjunction with the future Typhoon Roy in the Northern Hemisphere. Over the next few days, the system gradually developed while moving southwestward. Once it became a tropical cyclone, it was named Anne on January 8. The next day, Anne rapidly intensified, becoming the fourth major tropical cyclone to affect Vanuatu within four years. On January 11, Anne peaked in intensity while it was equivalent to a Category 5 on the Saffir–Simpson hurricane wind scale, and a Category 4 on the Australian tropical cyclone intensity scale. After turning southward on January 12, Anne struck New Caledonia, becoming the strongest tropical cyclone to affect the French Overseas Territory. The system subsequently weakened as it started to interact w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuvalu
Tuvalu ( or ; formerly known as the Ellice Islands) is an island country and microstate in the Polynesian subregion of Oceania in the Pacific Ocean. Its islands are situated about midway between Hawaii and Australia. They lie east-northeast of the Santa Cruz Islands (which belong to the Solomon Islands), northeast of Vanuatu, southeast of Nauru, south of Kiribati, west of Tokelau, northwest of Samoa and Wallis and Futuna, and north of Fiji. Tuvalu is composed of three reef islands and six atolls. They are spread out between the latitude of 5th parallel south, 5° and 10th parallel south, 10° south and between the longitude of 176th meridian east, 176° and 180th meridian, 180°. They lie west of the International Date Line. Tuvalu has a population of 10,507 (2017 census). The total land area of the islands of Tuvalu is .

Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are unofficially classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minut ...

Louisiade Archipelago
The Louisiade Archipelago is a string of ten larger volcanic islands frequently fringed by coral reefs, and 90 smaller coral islands in Papua New Guinea. It is located 200 km southeast of New Guinea, stretching over more than and spread over an ocean area of between the Solomon Sea to the north and the Coral Sea to the south. The aggregate land area of the islands is about , with Vanatinai (Tagula) being the largest. Rogeia, Samarai and Sariba lie closest to New Guinea, while Misima, Vanatinai, and Rossel islands lie further east. History The islands were discovered by a Spanish expedition led by Luis Váez de Torres in 1606, that was part of the Fernandez de Quiros fleet which had sailed from South America in search of Australia. The Torres expedition visited various islands including Basilaki Island, which he named ''San Buenaventura'' in July 1606. It is possible that Malay and Chinese sailors also visited the islands earlier. More than a century later, in 17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fujiwhara Effect
The Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one. Extratropical cyclones typically engage in binary interaction when within of one another, while tropical cyclones typically interact within of each other. Description When cyclones are in proximity of one another, their centers will circle each other cyclonically (counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere) about a point between the two systems due to their cyclonic wind circulations. The two vortices will be attra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Sea
The Coral Sea () is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea (french: Parc Naturel de la Mer de Corail) and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia. The sea contains numerous islands and reefs, as well as the world's largest reef system, the Great Barrier Reef (GBR), which was declared a World Heritage Site by UNESCO in 1981. All previous oil exploration projects were terminated at the GBR in 1975, and fishing is restricted in many areas. The reefs and islands of the Coral Sea are particularly rich in birds and aquatic life and are a popular tourist destination, both domestically and internat ...

Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
