Cyclone Zoe (1974)
Severe Tropical Cyclone Zoe was the List of the most intense tropical cyclones, second-most intense tropical cyclone on record within the Southern Hemisphere and was the strongest tropical cyclone worldwide in Tropical cyclones in 2002, 2002. The system was first noted on December 23, 2002, as a tropical depression that had developed, within the South Pacific Convergence Zone to the east of Tuvalu. Over the next couple of days, the system moved southwestwards and crossed the International Dateline early on December 25. After this, the system became better organized and was declared to be a tropical cyclone and named Zoe later that day. Zoe subsequently rapidly intensified in very favorable conditions as it continued to move west-southwest towards the Solomon Islands. The system subsequently became a Category 5 tropical cyclone on both the Tropical cyclone scales, Australian tropical cyclone intensity scale and the Saffir-Simpson hurricane wind scale on December 27. The system subs ...

Tikopia
Tikopia is a high island in the southwestern Pacific Ocean. It forms a part of the Melanesian nation state of Solomon Islands but is culturally Polynesian. The first Europeans arrived on 22 April 1606 as part of the Spanish expedition of Pedro Fernandes de Queirós. Location and geography Covering an area of , the island is the remnant of an extinct volcano. Its highest point, Mt. Reani, reaches an elevation of above sea level. Lake Te Roto covers an old volcanic crater which is deep. Tikopia's location is relatively remote. It is sometimes grouped with the Santa Cruz Islands. Administratively, Tikopia belongs to Temotu Province as the southernmost of the Solomon Islands. Some discussions of Tikopian society include its nearest neighbour, the even tinier island of Anuta. History as a Polynesian outlier While it is located in Melanesia, the people of Tikopia are culturally Polynesian. Their language, Tikopian, is a member of the Samoic branch of the Polynesian languages. The ...

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 ...

Tropical Cyclone Formation Alert
A Tropical Cyclone Formation Alert (TCFA) is a bulletin released by the U.S. Navy-operated Joint Typhoon Warning Center in Honolulu, Hawaii or the Fleet Weather Center in Norfolk, Virginia, warning of the possibility of a tropical cyclone forming from a tropical disturbance that has been monitored. Such alerts are generally always issued when it is fairly certain that a tropical cyclone will form and are not always released before cyclone genesis, particularly if the cyclone appears suddenly. The TCFA consists of several different checks that are performed by the on-duty meteorologist of the system and its surroundings. If the condition being checked is met, a certain number of points are given to the system. Parts of the TCFA Section 1 The first section of the TCFA contains information on the area of the alert as well as the estimated center of the circulation. The estimated maximum sustained winds are provided as well. Section 2 The second section generally contains more specif ...

Joint Typhoon Warning Center
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies. Their warnings are intended for the protection of primarily military ships and aircraft as well as military installations jointly operated with other countries around the world. Its U.S. Navy components are aligned with the Naval Meteorology and Oceanography Command. History The origins of the Joint Typhoon Warning Center (JTWC) can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time the center ...

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 ...

High Pressure
In science and engineering the study of high pressure examines its effects on materials and the design and construction of devices, such as a diamond anvil cell, which can create high pressure. By ''high pressure'' is usually meant pressures of thousands (kilobars) or millions (megabars) of times atmospheric pressure (about 1 bar or 100,000 Pa). History and overview Percy Williams Bridgman received a Nobel Prize in 1946 for advancing this area of physics by several magnitudes of pressure (400 MPa to 40,000 MPa). The list of founding fathers of this field includes also the names of Harry George Drickamer, Tracy Hall, Francis P. Bundy, Leonid F. Vereschagin, and Sergey M. Stishov. It was by applying high pressure as well as high temperature to carbon that man-made diamonds were first produced as well as many other interesting discoveries. Almost any material when subjected to high pressure will compact itself into a denser form, for example, quartz, also called silica or silicon di ...

Subtropical Ridge
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as Subtropics, subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Origin of the term A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Flogging a dead horse#Earlier meaning, Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. If they got advances from the ship's paymaster, they would incur debt. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "d ...

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 ...

Samoan Islands
The Samoan Islands ( sm, Motu o Sāmoa) are an archipelago covering in the central South Pacific, forming part of Polynesia and of the wider region of Oceania. Administratively, the archipelago comprises all of the Independent State of Samoa and most of American Samoa (apart from Swains Island, which is geographically part of the Tokelau Islands). The land masses of the two Samoan jurisdictions are separated by of ocean at their closest points. The population of the Samoan Islands is approximately 250,000. The inhabitants have in common the Samoan language, a culture known as '' fa'a Samoa,'' and an indigenous form of governance called '' fa'amatai''. Samoans are one of the largest Polynesian populations in the world, and most are of exclusively Samoan ancestry. The oldest known evidence of human activity in the Samoan Islands dates to around 1050 BCE. It comes from a Lapita site at Mulifanua wharf on Upolu island. In 1768, the eastern islands were visited by the French ...

List Of Retired South Pacific Tropical Cyclone Names
Tropical cyclones are non-frontal, low-pressure systems that develop, within an environment of warm sea surface temperatures and little vertical wind shear aloft. Within the South Pacific, names are assigned from a pre-determined list, to such systems, once they reach or exceed ten-minute sustained wind speeds of 65 km/h (40 mph), near the center, by either the Fiji Meteorological Service or New Zealand's MetService. Within the South Pacific, tropical cyclones have been officially named since the 1964–65 South Pacific cyclone season, though a few meteorological papers show that a few tropical cyclones were named before 1964–65. The names of significant tropical cyclones that have caused a high amount of damage and/or caused a significant number of deaths are retired from the lists of tropical cyclone names by the World Meteorological Organization's RA V Tropical Cyclone Committee at their bi-annual meeting. Within the South Pacific, there have been a total of ...
