Cyclone Hola
Severe Tropical Cyclone Hola had significant effects across Vanuatu in March 2018, resulting in the deaths of three people. Forming as a broad tropical disturbance on 5 March, the system slowly consolidated over the next few days before developing into a tropical cyclone on 6 March. Afterwards, a pinhole eye began to emerge and rapid intensification ensued. Cyclone Hola caused extensive damage in Vanuatu, damaging or destroying 1,709 structures, ruining crops, and killing three people. Impacts were most severe in Ambrym where half of the areas homes were damaged and people suffered from food shortages. Ambae, already dealing with the disruptive effects of a volcanic eruption, had major damage. Several other provinces reported varying degrees of lesser impact. Fiji, New Caledonia, and New Zealand were also affected by the cyclone. The former two experienced negligible effects while the latter saw heavy rain and strong winds. Effects in New Zealand were less than initially fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Outflow (meteorology)
Outflow, in meteorology, is air that flows outwards from a storm system. It is associated with ridging, or anticyclonic flow. In the low levels of the troposphere, outflow radiates from thunderstorms in the form of a wedge of rain-cooled air, which is visible as a thin rope-like cloud on weather satellite imagery or a fine line on weather radar imagery. For observers on the ground, a thunderstorm outflow boundary often approaches in otherwise clear skies as a low, thick cloud that brings with it a gust front. Low-level outflow boundaries can disrupt the center of small tropical cyclones. However, outflow aloft is essential for the strengthening of a tropical cyclone. If this outflow is restricted or undercut, the tropical cyclone weakens. If two tropical cyclones are in close proximity, the upper-level outflow from the upwind system can limit the development of the other system. Thunderstorms For thunderstorms, outflow tends to indicate the development of a system. Large quan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maré Island
Maré Island or Nengone (french: Île de Maré) is the second-largest of the Loyalty Islands, in the archipelago of New Caledonia, an overseas territory of France in the Pacific Ocean. The island is part of the commune (municipality) of Maré, in the Loyalty Islands Province of New Caledonia. Geography The island is long and 16 to 33 km (10 to 20 miles) wide. It lies northeast of Grande Terre, New Caledonia's mainland. Like its neighbor to the north Lifou, Maré is a raised coral atoll, a former atoll that has been lifted about 120 meters. The interior of the island is the former lagoon, surrounded by a rim of higher land that was the ring of reef islets. Its fossil coral rock is honeycombed with caves, pools, and pits of all sizes, whose sharp edges make for difficult walking. Because of the lifting, the current shoreline is relatively recent and supports only short sections of nearshore fringing reef, unlike the extensive barrier reef found on the main island of Ne ...

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 ...

Pentecost Island
Pentecost Island is one of the 83 islands that make up the South Pacific nation of Vanuatu. It lies due north of capital Port Vila. Pentecost Island is known as in French and in Bislama. The island was known in its native languages by names such as ''Vanu Aroaroa'', although these names are not in common use today. Pentecost has also been referred to as ''Raga'' or ''Araga'', a tribal name that originated in the north but is now widely applied to the whole island. In old sources, it is occasionally referred to as Whitsuntide Island. Geography Pentecost is a lush, mountainous island which stretches north to south over some . It has an area of . The mountain range, of which the highest is Mount Vulmat (), marks the dividing line between the humid, rainy eastern coast and the more temperate western coast. The coastal plains, cross-cut by small torrents, are generally very green and ideally suited for plantations and livestock. The climate on Pentecost is humid tropical ...

Beaufort Scale
The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale. History The scale was devised in 1805 by the Irish hydrographer Francis Beaufort (later Rear Admiral), a Royal Navy officer, while serving on . The scale that carries Beaufort's name had a long and complex evolution from the previous work of others (including Daniel Defoe the century before) to when Beaufort was Hydrographer of the Navy in the 1830s, when it was adopted officially and first used during the voyage of HMS ''Beagle'' under Captain Robert FitzRoy, who was later to set up the first Meteorological Office (Met Office) in Britain giving regular weather forecasts. In the 18th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective – one man's "stiff breeze" might be another's "soft breeze". Beaufort succeeded in standardising the sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
