Cyclone Ula
Severe Tropical Cyclone Ula was a powerful and long-lived tropical cyclone during late December 2015 and mid-January 2016. It originated from a tropical disturbance on December 26, 2015, east of the Solomon Islands. Moving generally east, development was initially slow and the system finally reached cyclone strength—having gale-force winds—on December 30. The newly christened Tropical Cyclone Ula turned sharply south and rapidly intensified, attaining hurricane-strength the following day. A shift to the southwest brought the system close to the northern islands of Tonga on January 2, 2016. It subsequently brushed several islands in the Lau Group of Fiji before weakening. Nearly degrading to a tropical depression, Ula turned to the northwest and regained strength. After turning back to the southwest, it achieved its peak intensity as a Category 4 on the Australian scale with winds of 185 km/h (115 mph) on January 10. Thereafter, the storm bypas ...

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] |
Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vavaʻu
Vavau is an island group, consisting of one large island ( ʻUtu Vavaʻu) and 40 smaller ones, in Tonga. It is part of Vavaʻu District, which includes several other individual islands. According to tradition, the Maui god created both Tongatapu and Vavau, but put a little more effort into the former. Vavau rises above sea level at Mount Talau. The capital is Neiafu, situated at the Port of Refuge (Puatalefusi or Lolo-a-Halaevalu). History Myths and legends In Polynesia, it is said that the islands were created by the god Maui, who reached into the bottom of the sea with his magic hook, caught something on it, and pulled it up to the sea surface, and it became the islands of Vavau. Recorded history Don Francisco Mourelle de la Rúa, commanding the Spanish frigate ''Princesa'', was the first European to come to Vavau, which he did on 4 March 1781. He charted Vavaʻu as ''Martín de Mayorga'', naming it after the man who was the Viceroy of New Spain at that time. Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Of Emergency
A state of emergency is a situation in which a government is empowered to be able to put through policies that it would normally not be permitted to do, for the safety and protection of its citizens. A government can declare such a state during a natural disaster, civil unrest, armed conflict, medical pandemic or epidemic or other biosecurity risk. ''Justitium'' is its equivalent in Roman law—a concept in which the Roman Senate could put forward a final decree (''senatus consultum ultimum'') that was not subject to dispute yet helped save lives in times of strife. Relationship with international law Under international law, rights and freedoms may be suspended during a state of emergency, depending on the severity of the emergency and a government's policies. Use and viewpoints Though fairly uncommon in democracies, dictatorship, dictatorial regimes often declare a state of emergency that is prolonged indefinitely for the life of the regime, or for extended periods of t ...

ʻAkilisi Pōhiva
Samiuela ʻAkilisi Pōhiva (7 April 1941 – 12 September 2019) was a Tongan pro-democracy activist and politician. Pohiva, the leader of the Democratic Party of the Friendly Islands (DPFI), served as the Prime Minister of Tonga from 2014 to his death in 2019. He was only the fourth commoner to serve as Prime Minister (after Shirley Baker in the 1880s, Siosateki Tonga in the 1890s and Feleti Sevele in the 2000s), and the first commoner to be elected to that position by Parliament rather than appointed by the King. Personal life Pōhiva worked as a teacher and later studied at the University of the South Pacific before joining the Tongan Teacher Training Staff. He became active in Tonga's pro-democracy movement in the 1980s, and in 1981 he co-founded their monthly radio programme, "Matalafo Laukai". In 1984, he was dismissed from the civil service as punishment for his criticism of the government; he subsequently sued them successfully for unfair dismissal. He then founded th ...

Prime Minister Of Tonga
The prime minister of Tonga (historically referred to as the premier) is the country's head of government. Tonga is a monarchy with the king, currently Tupou VI, former prime minister, as head of state. The current prime minister is Siaosi Sovaleni, who was elected on 15 December 2021 and appointed on 27 December 2021. Sovaleni was elected with 16 votes. The office of prime minister was established by the Constitution of 1875, whose article 51 stipulates that the prime minister and other ministers are appointed and dismissed by the king. The prime minister is assisted by the deputy prime minister. 2000s democratization During the 2000s, the country experienced an increase in democratization. In March 2006, King Tāufaʻāhau Tupou IV appointed Feleti Sevele, a moderate member of the Human Rights and Democracy Movement, as prime minister. Sevele was the first commoner to hold this post since Shirley Waldemar Baker in 1881. All the prime ministers since Baker had been members ...

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. They are term ...

Coordinated Universal 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
