Cyclones Katrina And Victor–Cindy
Severe Tropical Cyclones Katrina and Victor–Cindy were a long-lived pair of related tropical cyclones, which moved around the coast of northeastern Australia during parts of January and February 1998, before eventually moving into the southern Indian Ocean. Katrina was the fourth tropical cyclone and named storm of the 1997–98 Australian region cyclone season; Victor–Cindy was the seventh tropical cyclone and named storm of the 1997–98 Australian region cyclone season; after moving into the South-West Indian Ocean, Victor–Cindy became the fifth tropical cyclone and the fourth named storm of the 1997–98 South-West Indian Ocean cyclone season. Katrina developed on 1 January and meandered within the Coral Sea between the Queensland coast and Vanuatu for the next three weeks, before degenerating into a remnant low near Far North Queensland on 25 January. After its decay, the remnants of Katrina moved westward over Cape York Peninsula and the Gulf of Carpentaria, before reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1997–98 Australian Region Cyclone Season
The 1997–98 Australian region cyclone season was a slightly below average tropical cyclone season. It ran from 1 November 1997 to 30 April 1998. The regional tropical cyclone operational plan also defines a ''tropical cyclone year'' separately from a ''tropical cyclone season'', and the "tropical cyclone year" ran from 1 July 1997 to 30 June 1998. Tropical cyclones in this area were monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; and TCWC Port Moresby in Papua New Guinea. __TOC__ Systems ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/11/1997 till:01/05/1998 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/11/1997 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend ...

Rapid Intensification
In meteorology, rapid intensification is a situation where a tropical cyclone intensifies dramatically in a short period of time. The United States National Hurricane Center defines rapid intensification as an increase in the maximum sustained winds of a tropical cyclone of at least in a 24-hour period. Necessary conditions External In order for rapid intensification to occur, several conditions must be in place. Water temperatures must be extremely warm (near or above ), and water of this temperature must be sufficiently deep such that waves do not churn deeper cooler waters up to the surface. Wind shear must be low; when wind shear is high, the convection and circulation in the cyclone will be disrupted. Dry air can also limit the strengthening of tropical cyclones. Internal Usually, an anticyclone in the upper layers of the troposphere above the storm must also be present for extremely low surface pressures to develop. This is because air must be converging towards the low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anticyclone
An anticyclone is a weather phenomenon defined as a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere as viewed from above (opposite to a cyclone). Effects of surface-based anticyclones include clearing skies as well as cooler, drier air. Fog can also form overnight within a region of higher pressure. Mid-tropospheric systems, such as the subtropical ridge, deflect tropical cyclones around their periphery and cause a temperature inversion inhibiting free convection near their center, building up surface-based haze under their base. Anticyclones aloft can form within warm-core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large-scale sinking such as a subtropical ridge. The evolution of an anticyclone depends upon variables such as its size, intensity, and extent of moist con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Espiritu Santo
Espiritu Santo (, ; ) is the largest island in the nation of Vanuatu, with an area of and a population of around 40,000 according to the 2009 census. Geography The island belongs to the archipelago of the New Hebrides in the Pacific region of Melanesia. It is in the Sanma Province of Vanuatu. The town of Luganville, on Espiritu Santo's southeast coast, is Vanuatu's second-largest settlement and the provincial capital. Roads run north and west from Luganville, but most of the island is far from the limited road network. Around Espiritu Santo lie a number of small islands and islets; among them are: Dany Island, Araki, Elephant Island, Sakao, Lataroa, Lataro, Thion, Malohu, Malwepe, Malvapevu, Malparavu, Maltinerava, Oyster Island, Tangoa, and Bokissa. Vanuatu's highest peak is the 1879 metre (6165 foot) Mount Tabwemasana in west-central Espiritu Santo.

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 ...

Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rennell Island
Rennell Island, locally known as Mugaba, is the main island of two inhabited islands that make up the Rennell and Bellona Province in the nation state of Solomon Islands. Rennell Island has a land area of that is about long and wide. It is the second largest raised coral atoll in the world with the largest lake in the insular Pacific, Lake Tegano, a lake that is listed as a World Heritage Site.

Fiji Meteorological Service
The Fiji Meteorological Service (FMS) is a Department of the government of Fiji responsible for providing weather forecasts and is based on the grounds of Nadi Airport in Nadi. The current director of Fiji Meteorological Service is Misaeli Funaki. Since 1985, FMS has been responsible for naming and tracking tropical cyclones in the Southwest Pacific region. Current Meteorologists working at FMS have a Graduate Diploma in Meteorology from the Australian Bureau of Meteorology. History Before World War II, weather observations in Fiji were the responsibility of the harbour board and limited to recording various meteorological details at various locations around the island nation. During the 1939 Defence Conference in Wellington, New Zealand, Fiji's capital Suva was identified as the location of an upgraded meteorological service for the Pacific region. As a result, a facility was established at Laucala Bay during 1940, before it was expanded during the following year to support the o ...

Cyclone Susan
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 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 formation and ...
