2004–05 South Pacific Cyclone Season
The 2004–05 South Pacific cyclone season was an above-average season in which tropical cyclones formed within the South Pacific Ocean to the east of 160°E. The season officially ran from November 1, 2004 to April 30, 2005, however a tropical cyclone could form at any time between July 1, 2004 and June 30, 2005 and would count towards the season total. The season got off to an early start, when Tropical Depression 01F developed near the Solomon Islands on October 28, three days before the official start of the season. The final disturbance of the season dissipated as the season was drawing to a close on May 1. The season was above-average in terms of activity, with 9 tropical cyclones and 5 severe tropical cyclones forming during the season. The season featured Cyclone Percy, the most intense of the season in terms of pressure. During the season, tropical cyclones are officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BOM) and New Zea ...

Cyclone Percy
Cyclone Percy was the seventh named storm of the 2004–05 South Pacific cyclone season and the fourth and final severe tropical cyclone to form during the 2004–05 South Pacific cyclone season. Cyclone Percy originated as a tropical disturbance on February 23. Over the course of the next few days, the system organized while moving east-southeastward, before intensifying into a Category 1 tropical cyclone on the Australian region scale on February 26. The system quickly intensified, reaching Category 4 status later that day. On the next day, Percy was steered southward by a blocking high-pressure system, ridge of high pressure, while stretched out the structure of the storm into an elliptical shape, weakening it back to Category 3 status. Afterward, the storm rapidly reintensified, reaching its peak intensity as a Category 5 tropical cyclone on March 2. Afterward, Percy encountered increasing wind shear and weakened once again, turning southeastward on the next day. On March 5, Pe ...

Cyclone Nancy
Cyclone Nancy (RSMC Nadi designation: ''09F'', JTWC designation: ''18P'') was the second in a series of four severe tropical cyclones to impact the Cook Islands during February 2005. Forming out of an area of low pressure on February 10, Nancy quickly organized into a small, but intense, cyclone. By February 14, the storm explosively intensified into a Category 4 severe tropical cyclone with winds peaking at 175 km/h (110 mph 10-minute winds)The maximum sustained wind reported by the Regional Specialized Meteorological Center in Nadi, Fiji are measured by 10-minute standards and a minimum barometric pressure of 935 hPa (mbar). Over the following day, increasing wind shear rapidly weakened the cyclone and by February 17, it transitioned into an extratropical cyclone shortly before being absorbed by Cyclone Olaf. Already impacted by Cyclone Meena in early February, the Cook Islands sustained significant damage from Cyclone Nancy. Several homes ...

Fujiwhara Interaction
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 attr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manuae (Cook Islands)
Manuae is an uninhabited atoll in the southern group of the Cook Islands, 100 kilometres south-east of Aitutaki. It is administratively part of Aitutaki, but it does not belong to any district or tapere of Aitutaki. It is, however, part of Arutanga-Reureu-Nikaupara Constituency. Geographic description Manuae is a true atoll sitting on the peak of a submerged volcano which descends over 4000 meters to the ocean bed. It comprises two horseshoe-shaped islets, ''Manuae'' to the west and ''Te Au O Tu'' to the east, with a total area of 6 km2 on either side of a lagoon about 7 km x 4 km. Manuae has an area of 2.1 km2, while Te Au O Tu's is 3.9 km2. The lagoon is 13 km2 in size, shallow and subject to large shifting sand banks. A coral reef surrounds the atoll, and there is no passage through the reef. The island is a marine park and is an important breeding ground for seabirds and marine turtles in the Central Pacific. The offshore waters of Manuae ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane
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 ...

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] |
Atmospheric Convection
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. Overview There are a few general archetypes of atmospheric instability that are used to explain convection (or lack thereof). A necessary (but not sufficient) condition for convection is that the environmental lapse rate (the rate of decrease of temperature with height) is steeper than the lapse rate experienced by a rising parcel of air. When this condition is met, upward-displaced air parcels can become buoyant and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Cook Islands
The Northern Cook Islands is one of the two chains of atolls which make up the Cook Islands. Lying in a horizontal band between 9° and 13°30' south of the Equator, the chain consists of the atolls of Manihiki, Nassau, Penrhyn, Pukapuka, Rakahanga and Suwarrow, along with the submerged Tema Reef. Geography The chain forms a roughly inverted triangular shape, stretching from Penrhyn in the northeast to Pukapuka in the northwest and to Suwarrow in the south. The Northern Cook Islands are separated from the Southern Cook Islands by a wide stretch of the Pacific Ocean, with the nearest part of the Southern chain being Palmerston Island, due south of Suwarrow. With an area of just 21 sq. km. and a population of 1,041 (according to the 2016 census), the islands only account for some 6% of the Cooks' population and 9% of the land area. Almost all of this population is on the three islands of Pukapuka, Manihiki, and Penrhyn. The two chains are also geographically different: although ...

Tongatapu
Tongatapu is the main island of Tonga and the site of its capital, Nukualofa. It is located in Tonga's southern island group, to which it gives its name, and is the country's most populous island, with 74,611 residents (2016), 70.5% of the national population, on . Based on Google Earth Pro, its maximum elevation is at least above sea level along Liku Road at 21 degrees 15 minutes and 55.7 seconds south 175 degrees 08 minutes 06.4 seconds west, but could be even higher somewhere else. Tongatapu is Tonga's centre of government and the seat of its monarchy. Tongatapu has experienced more rapid economic development than the other islands of Tonga, and has thus attracted many internal migrants from them. Geography The island is (or including neighbouring islands) and rather flat, as it is built of coral limestone. The island is covered with thick fertile soil consisting of volcanic ash from neighbouring volcanoes. At the steep coast of the south, heights reach an average of , a ...

Vanuatu
Vanuatu ( or ; ), officially the Republic of Vanuatu (french: link=no, République de Vanuatu; bi, Ripablik blong Vanuatu), is an island country located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is east of northern Australia, northeast of New Caledonia, east of New Guinea, southeast of the Solomon Islands, and west of Fiji. Vanuatu was first inhabited by Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Fernandes de Queirós, who arrived on the largest island, Espíritu Santo, in 1606. Queirós claimed the archipelago for Spain, as part of the colonial Spanish East Indies, and named it . In the 1880s, France and the United Kingdom claimed parts of the archipelago, and in 1906, they agreed on a framework for jointly managing the archipelago as the New Hebrides through an Anglo-French condominium. An independence movement arose in the 1970s, and the Republic of Vanuatu was fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
