Hurricane Val
Severe Tropical Cyclone Val (also known as Hurricane Val) was considered to be the worst tropical cyclone to affect the Samoan Islands since the 1889 Apia cyclone. The system was first identified during the opening days of December 1991, as a small circulation, within the Intertropical Convergence Zone to the north of Tokelau. Over the next few days, the system moved westwards towards Rotuma and Tuvalu and gradually developed further, before it was named Val on December 5, after it had become a category 1 tropical cyclone on the Australian tropical cyclone intensity scale. The system subsequently continued to intensify as it moved towards the Samoan Islands and peaked as a category 4 severe tropical cyclone, as it made landfall on the island of Savaii on December 6. After Val had passed over the island, weakening upper-level winds caused the system to slow down before it made a sharp clockwise loop which almost brought it over Savaii for a second time. On December 9, Val comple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuvalu
Tuvalu ( ) is an island country in the Polynesian subregion of Oceania in the Pacific Ocean, about midway between Hawaii and Australia. It lies 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 spread out between the latitude of 5th parallel south, 5° and 10th parallel south, 10° south and between the longitude of 176th meridian east, 176° and 180th meridian, 180°. They lie west of the International Date Line. The 2022 census determined that Tuvalu had a population of 10,643, making it List of countries and dependencies by population, the second-least populous country in the world, behind Vatican City. Tuvalu's total land area is . The first inhabitants of Tuvalu were Polynesians arriving as part of the History of the Polynesian people, migration of ...

Outflow (meteorology)
Outflow, in meteorology, is air that flows outwards from a storm system. It is associated with ridging, or anticyclone, 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 close, 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] |
Cyclone Ofa
Severe Tropical Cyclone Ofa was a powerful tropical cyclone that caused severe damage in Polynesia in February 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 S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
