Cyclone Ofa
Severe Tropical Cyclone Ofa was a powerful tropical cyclone that caused severe damage in Polynesia in February of 1990. The system was first noted on January 27, 1990, near Tuvalu, as a shallow tropical depression that had developed within the South Pacific Convergence Zone. The cloud pattern slowly organized, and on January 31, while located east of Tuvalu, Ofa attained cyclone intensity. Moving slowly southeast, Ofa developed storm-force winds. It attained hurricane-force winds on February 2. Cyclone Ofa reached peak intensity on February 4. Shortly after, its peak Ofa began to weaken over a less favourable environment. Ofa was declared an extratropical cyclone on February 8, though the system was still tracked by meteorologists until February 10. Ofa produced gales or high winds or gales on many islands, resulting in widespread damage due to a combination of storm surge and high seas. In all, eight people were killed and damage totaled to . The worst effects were recorded in Sa ...

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 5° and 10° south and between the longitude of 176° and 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 . The first inhabitants of Tuvalu were Polynesians, according to well-established theories regarding a migration of Polynesians into the Pacific that began about three thousand years ago. Long before European cont ...

Australian Tropical Cyclone Intensity Scale
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-minu ...

Fakaofo
Fakaofo, formerly known as Bowditch Island, is a South Pacific Ocean atoll located in the Tokelau Group. The actual land area is only about 3 km2 (1.1 sq mi), consisting of islets on a coral reef surrounding a central lagoon of some 45 km2. According to the 2006 census 483 people officially live on Fakaofo (however just 370 were present at census night). Of those present 70% belong to the Congregational Church and 22% to the Catholic Church. Geography and government The main settlement on the island is Fale on Fale Islet, towards the western side of the atoll. Located two kilometres to the west of it is the relatively large Fenua Fala Islet, where a second settlement was established in 1960. Other islets in the group include Teafua, Nukumatau, Nukulakia, Fenua Loa, Saumatafanga, Motu Akea, Matangi, Lalo, and Mulifenua. Fakaofo's Council of Elders is made up of citizens over the age of 60. History The island was sighted by the whale ship ''General Jackson' ...

Nukunonu
Nukunonu is the largest atoll within Tokelau, a dependency of New Zealand, in the south Pacific Ocean. It comprises 30 islets surrounding a central lagoon, with about of land area and a lagoon surface area of . Motuhaga is the only islet that has inhabitants. It has an estimated population of 448. History The first European vessel known to have come upon Nukunonu was the Royal Navy ship , in 1791, whose captain, Edward Edwards, named Duke of Clarence Island in honor of Prince William, Duke of Clarence and St Andrews (1765-1837), the third son of King George III and later king himself, as William IV. At the time, the ''Pandora'' was searching for mutineers from . During the early 19th century, Nukunonu's inhabitants were converted to Roman Catholicism by Samoan missionaries. Between 1856 and 1979, the United States claimed that it held sovereignty over the island and the other Tokelauan atolls. In 1979, the U.S. conceded that Tokelau was under New Zealand sovereignty, a ...

Wallis (island)
Wallis ( Wallisian: ''Uvea'') is a Polynesian atoll/island in the Pacific Ocean belonging to the French overseas collectivity (''collectivité d'outre-mer'', or ''COM'') of Wallis and Futuna. It lies north of Tonga, northeast of Fiji, east-northeast of the Hoorn Islands, east of Fiji's Rotuma, southeast of Tuvalu, southwest of Tokelau and west of Samoa. Its area is almost with 8,333 people. Its capital is Mata Utu. Roman Catholicism is the predominant religion. Its highest point is Mount Lulu Fakahega (). Wallis is of volcanic origin with fertile soil and some remaining lakes. Rainfall is plentiful. It was part of the Tongan maritime empire from around the 13th to 16th century. By that time the influence of the Tui Tonga had declined so much that Uvea became important in itself. The big fortress of Talietumu close to Lotoalahi in Mua was the last holdout of the Tongans until they were defeated. The island was renamed "Wallis" after a Cornish navigator, Captain Samuel W ...

Cyclone Bebe
Severe Tropical Cyclone Bebe, also known as Hurricane Bebe, was a pre-season storm during October 1972 in the South Pacific Ocean that severely affected Fiji, the Ellice Islands (now Tuvalu), and the Gilbert Islands (now Kiribati). Meteorological history The origins of Severe Tropical Cyclone Bebe can be traced to a pair of tropical disturbances, which were first noted on either side of the Equator near the 175th meridian west during October 16. The first system developed in the Northern Hemisphere and eventually developed into Typhoon Olga, before it impacted the Marshall Islands. The second disturbance developed within the South Pacific Ocean and started to move westwards, before it started to show signs of developing into a tropical cyclone during October 19. Over the next couple of days, the system started to move south-westwards and was named Bebe by the New Zealand Meteorological Service, after it had become a category 1 tropical cyclone on the modern-day Australian scal ...

Sea Surface Temperature
Sea surface temperature (SST), or ocean surface temperature, is the ocean temperature close to the surface. The exact meaning of ''surface'' varies according to the measurement method used, but it is between and below the sea surface. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Localized areas of heavy snow can form in bands downwind of warm water bodies within an otherwise cold air mass. Warm sea surface temperatures are known to be a cause of tropical cyclogenesis over the Earth's oceans. Tropical cyclones can also cause a cool wake, due to turbulent mixing of the upper of the ocean. SST changes diurnally, like the air above it, but to a lesser degree. There is less SST variation on breezy days than on calm days. In addition, ocean currents such as the Atlantic Multidecadal Oscillation (AMO), can affect SST's on multi-decadal time scales, a major impact results from the global thermohaline ...

Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term " cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. T ...
