Cyclone Sose
Tropical Cyclone Sose was a moderate storm system that chiefly impacted the island nation of Vanuatu in early April 2001. The developing cyclone was first detected on April 3, while situated well to the northeast of Vanuatu. As atmospheric conditions became more conducive to intensification, the disturbance gradually consolidated as it drifted toward the west-southwest. After receiving the name Sose on April 5, the cyclone was driven southeastward, passing just west of Espiritu Santo and neighboring islands. Although it never made landfall, Sose was particularly expansive, producing a wide area of gale-force winds. The cyclone peaked in strength between April 7 and 8 with maximum 10-minute sustained winds of 110 km/h (70 mph) and 1-minute sustained winds of 130 km/h (80 mph), placing it at Category 2 intensity on the Australian tropical cyclone intensity scale. Ultimately, stronger wind shear and an increasingly hostile upper-air pattern took their toll on the ...

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 ...

Fetch (geography)
In oceanography wind fetch, also known as fetch length or simply fetch, is the length of water over which a given wind has blown without obstruction. Fetch is used in geography and meteorology and its effects are usually associated with sea state and when it reaches shore it is the main factor that creates storm surge which leads to coastal erosion and flooding. It also plays a large part in longshore drift. Fetch length, along with the wind speed (wind strength), and duration, determines the size (sea state) of waves produced. If the wind direction is constant, the longer the fetch and the greater the wind speed, the more wind energy is transferred to the water surface and the larger the resulting sea state will be.''November's fury'' by Michael Schumaker University of Minnesota Press Sea state will increase over time until local energy dissipation balances energy transfer to the water from the wind and a fully developed sea results.

Fiji Meteorological Service
The Fiji Meteorological Service (FMS) is a Department of the government of Fiji responsible for providing weather forecasts and is based on the grounds of Nadi Airport in Nadi. The current director of Fiji Meteorological Service is Misaeli Funaki. Since 1985, FMS has been responsible for naming and tracking tropical cyclones in the Southwest Pacific region. Current Meteorologists working at FMS have a Graduate Diploma in Meteorology from the Australian Bureau of Meteorology. History Before World War II, weather observations in Fiji were the responsibility of the harbour board and limited to recording various meteorological details at various locations around the island nation. During the 1939 Defence Conference in Wellington, New Zealand, Fiji's capital Suva was identified as the location of an upgraded meteorological service for the Pacific region. As a result, a facility was established at Laucala Bay during 1940, before it was expanded during the following year to support the o ...

Universal Coordinated Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ...

Rainband
A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure. Rainbands within tropical cyclones are curved in orientation. Rainbands of tropical cyclones contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes. Rainbands associated with cold fronts can be warped by mountain barriers perpendicular to the front's orientation due to the formation of a low-level barrier jet. Bands of thunderstorms can form with sea breeze and land breeze boundaries, if enough moisture ...

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 ...

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 ...

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 ...

Coastal Flooding
Coastal flooding normally occurs when dry and low-lying land is submerged by seawater. The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding. Flood damage modelling was limited to local, regional or national scales. However, with the presence of climate change and an increase in the population rates, flood events have intensified and called for a global interest in finding out different methods with both spatial and temporal dynamics. The seawater can flood the land via several different paths: direct flooding, overtopping of a barrier, breaching of a barrier. Coastal flooding is largely a natural event, however human influence on the coastal environment can exacerbate coastal flooding. Extraction of water from groundwater reservoirs in the coastal zone can instigate subsidence of the land, thus increasing the risk of flooding. Engineered protection struc ...
