2009–10 South Pacific Cyclone Season
The 2009–10 South Pacific cyclone season began on December 3, 2009 with the formation of Tropical Disturbance 01F, 32 days after the cyclone season had officially begun on November 1, 2009. The season ended on April 30, 2010. These dates conventionally delimit the period of each year when most tropical cyclones form in the southern Pacific Ocean east of longitude, 160°E. Additionally, the regional tropical cyclone operational plan defines a ''tropical cyclone year'' separately from a ''tropical cyclone season''; the "tropical cyclone year" began on July 1, 2009 and ended on June 30, 2010. Tropical cyclones between 160°E and 120°W and north of 25°S are monitored by the Fiji Meteorological Service. Those that move south of 25°S are monitored by the Tropical Cyclone Warning Centre in Wellington, Wellington, New Zealand. The first tropical disturbance of the season formed on December 3, about 1015 km (700 mi) to the north of Suva, Suva, Fiji and later intensified into ...

Cyclone Ului
Severe Tropical Cyclone Ului was one of the fastest intensifying tropical cyclones on record, strengthening from a tropical storm to a Category 5 equivalent cyclone within a 30-hour span in March 2010. Throughout Queensland, Australia, infrastructural damage from the storm amounted to A$20 million (US$18 million) and agricultural losses reached A$60 million (US$54 million). Meteorological history Severe Tropical Cyclone Ului was first identified by the Fiji Meteorological Service (FMS) late on 9 March 2010 roughly north of Hiw Island, Vanuatu. At that time, the system was classified as Tropical Disturbance 13F. Early the following day, the system became sufficiently organised for the FMS to upgrade the disturbance to a tropical depression. Several hours later, the Joint Typhoon Warning Center (JTWC) also began monitoring the system. By this time, deep convection had developed around a low-level circulation and banding features had formed. A slow west ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyclone Gene
Severe Tropical Cyclone Gene was the deadliest storm as well as the most damaging tropical cyclone of the 2007–08 South Pacific cyclone season east of 160ºE. RSMC Nadi monitored Gene as the 12th tropical disturbance, as well as the fourth tropical cyclone and the third severe tropical cyclone to form west of 160ºE during the 2007–08 South Pacific cyclone season. Gene was also recognised by RSMC Nadi as the fifth tropical cyclone and fourth severe tropical cyclone to form within the South Pacific Ocean during the 2007-08 season. On January 25, a tropical disturbance formed within the Fijian Archipelago and was designated as Tropical Disturbance 12F. The next day it was upgraded to a tropical depression, whilst on January 27, RSMC Nadi named the depression as Cyclone Gene. Later that day Gene made landfall on Fiji, and caused 8 deaths and $51 million (2008, F$). Cyclone Gene then slowly intensified to a category three cyclone on both the Saffir–Simpson hurricane scale and t ... [...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] |
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] |
160th Meridian East
The meridian 160° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Asia, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole. The 160th meridian east forms a great circle with the 20th meridian west. In Antarctica, the meridian defines the border between the Australian Antarctic Territory and the Ross Dependency. From Pole to Pole Starting at the North Pole and heading south to the South Pole The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface.

Rotuma
Rotuma is a Fijian dependency, consisting of Rotuma Island and nearby islets. The island group is home to a large and unique Polynesian indigenous ethnic group which constitutes a recognisable minority within the population of Fiji, known as "Rotumans". Its population at the 2017 census was 1,594, although many more Rotumans live on mainland Fijian islands, totaling 10,000. Geography and geology The Rotuma group of volcanic islands are located (Suva to Ahau) north of Fiji. Rotuma Island itself is long and wide, with a land area of approximately , making it the 12th-largest of the Fiji islands. The island is bisected by an isthmus into a larger eastern part and a western peninsula. The isthmus is low and narrow, only wide, and is the site of Motusa village ( Itutiu district). North of the isthmus is Maka Bay, and in the south is Hapmafau Bay. There is a large population of coral reefs in these bays, and there are boat passages through them.

Equatorial Rossby Wave
Equatorial Rossby waves, often called planetary waves, are very long, low frequency water waves found near the equator and are derived using the equatorial beta plane approximation. Mathematics Using the equatorial beta plane approximation, f = \beta y, where ''β'' is the variation of the Coriolis parameter with latitude, \beta = \frac. With this approximation, the primitive equations become the following: * the continuity equation (accounting for the effects of horizontal convergence and divergence and written with geopotential height): ::\frac + c^2 \left ( \frac + \frac \right ) = 0 * the U-momentum equation (zonal component): ::\frac - v \beta y = -\frac * the V-momentum equation (meridional component): ::\frac + u \beta y = -\frac.Holton, James R., 2004: ''An Introduction to Dynamic Meteorology.'' Elsevier Academic Press, Burlington, MA, pp. 394–400. In order to fully linearize the primitive equations, one must assume the following solution: :: \beginu, v, \v ...

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 ...
