2018–19 Australian Region Cyclone Season
The 2018–19 Australian region cyclone season was an average season that saw the formation of 11 tropical cyclones, six of which intensified further to become severe tropical cyclones. The season officially began on 1 November 2018 and concluded on 30 April 2019; however, as evidenced by Tropical Low Liua in September 2018 and Tropical Cyclones Lili and Ann in May 2019, tropical cyclones can form at any time of the year. As such, any system existing between 1 July 2018 and 30 June 2019 would count towards the season total. During the season, tropical cyclones were officially monitored by the Bureau of Meteorology (BOM), the Indonesian Agency for Meteorology, Climatology and Geophysics (BMKG) in Jakarta, Indonesia, and the National Weather Service of Papua New Guinea in Port Moresby. The United States' Joint Typhoon Warning Center (JTWC) in Hawaii, and other national meteorological services such as MetService in New Zealand, Météo-France at La Réunion, and the Fiji Meteorologic ...

Cyclone Veronica
Severe Tropical Cyclone Veronica was a large and powerful tropical cyclone which brought major impacts to the Pilbara region of Western Australia during March 2019. The nineteenth tropical low, eighth tropical cyclone and fifth severe tropical cyclone on the 2018–19 Australian region cyclone season, Veronica first appeared as a tropical low near East Timor on 18 March 2019. The system was slow to develop initially while tracking southwestwards through the Timor Sea, but began to consolidate the following day. The storm was upgraded by the Australian Bureau of Meteorology (BOM) to a Category 1 tropical cyclone on the Australian scale at 18:00 UTC on 19 March, by which time a steady development trend had begun. Upon attaining Category 2 status at 06:00 UTC on 20 March, Veronica underwent a period of explosive intensification. The system became a severe tropical cyclone six hours later, and Category 4 just six hours after that. Veronica reached peak intensity at 06:00 UTC the foll ...

South Pacific Tropical Cyclone
A South Pacific tropical cyclone is a non-frontal, low pressure system that has developed, within an environment of warm sea surface temperatures and little vertical wind shear aloft in the South Pacific Ocean. Within the Southern Hemisphere there are officially three areas where tropical cyclones develop on a regular basis, these areas are the South-West Indian Ocean between Africa and 90°E, the Australian region between 90°E and 160°E and the South Pacific basin between 160°E and 120°W. The South Pacific basin between 160°E and 120°W is officially monitored by the Fiji Meteorological Service and New Zealand's MetService, while others like the Australian Bureau of Meteorology and the United States National Oceanic and Atmospheric Administration also monitor the basin. Each tropical cyclone year within this basin starts on July 1 and runs throughout the year, encompassing the tropical cyclone season which runs from November 1 and lasts until April 30 each season.

2018–19 South Pacific Cyclone Season
The 2018–19 South Pacific cyclone season was a below-average season that produced 5 tropical cyclones, 2 of which became severe tropical cyclones. The season officially runs from November 1, 2018 to April 30, 2019; however, a tropical cyclone could have formed at any time between July 1, 2018 and June 30, 2019 and would count towards the season total. During the season, tropical cyclones were officially monitored by the Fiji Meteorological Service, Australian Bureau of Meteorology, and New Zealand's MetService. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) also monitored the basin and issued warnings for American interests. RSMC Nadi attaches a number and an F suffix to tropical disturbances that form in or move into the basin, while the JTWC designates significant tropical cyclones with a number and a P suffix. The FMS, the BoM and MetService all use the Australian Tropical Cyclone Intensity Scale and estimate wind speeds over a period of ten minu ...

Tropical Cyclone Scales
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-minut ...

Cyclone Owen
Severe Tropical Cyclone Owen was an erratic and long-lived tropical cyclone that affected numerous regions within its long trek, especially Queensland, during December 2018. It was the fourth tropical low, the first tropical cyclone, and first severe tropical cyclone of the 2018–19 Australian region cyclone season. Owen developed on 29 November 2018 from an area of low pressure that was situated over the Solomon Islands; the system struggled to strengthen in a conflicting environment and degenerated to a tropical low on 3 December. The low drifted westward, and on 9 December, it made its first landfall in Queensland, before moving over the Gulf of Carpentaria, where more favourable conditions allowed it to re-organise. The system regenerated into a tropical cyclone on 12 December and rapidly intensified into a Category 3 severe tropical cyclone that night. At midnight on 13 December, Owen made landfall in the Northern Territory, before turning eastward and reaching peak intensi ...

El Niño
El Niño (; ; ) is the warm phase of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (approximately between the International Date Line and 120°W), including the area off the Pacific coast of South America. The ENSO is the cycle of warm and cold sea surface temperature (SST) of the tropical central and eastern Pacific Ocean. El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. El Niño phases are known to last close to four years; however, records demonstrate that the cycles have lasted between two and seven years. During the development of El Niño, rainfall develops between September–November. The cool phase of ENSO is es, La Niña, translation=The Girl, with SSTs in the eastern Pacific below average, and air pressure high in the eastern Pacific and low in the western Pacific. The ENSO cycle, including bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1996–97 Australian Region Cyclone Season
The 1996–97 Australian region cyclone season was an above average tropical cyclone season. It ran from 1 November 1996 to 30 April 1996. The regional tropical cyclone operational plan also defines a ''tropical cyclone year'' separately from a ''tropical cyclone season'', and the "tropical cyclone year" ran from 1 July 1996 to 30 June 1997. Tropical cyclones in this area were monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; and TCWC Port Moresby in Papua New Guinea. __TOC__ Season summary ImageSize = width:800 height:200 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/07/1996 till:01/06/1997 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/07/1996 Colors = id:canvas value:gray(0.88) id:GP value:red id:TL value:rgb(0.38,0.73,1) legend:T ...

Coral Sea
The Coral Sea () is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea (french: Parc Naturel de la Mer de Corail) and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia. The sea contains numerous islands and reefs, as well as the world's largest reef system, the Great Barrier Reef (GBR), which was declared a World Heritage Site by UNESCO in 1981. All previous oil exploration projects were terminated at the GBR in 1975, and fishing is restricted in many areas. The reefs and islands of the Coral Sea are particularly rich in birds and aquatic life and are a popular tourist destination, both domestically and internat ...

Indonesian Archipelago
The islands of Indonesia, also known as the Indonesian Archipelago ( id, Kepulauan Indonesia) or Nusantara, may refer either to the islands comprising the country of Indonesia or to the geographical groups which include its islands. History The exact number of islands comprising Indonesia varies among definitions and sources. According to the Law No 9/1996 on Maritime Territory of Indonesia, of 17,508 officially listed islands within the territory of the Republic of Indonesia. According to a geospatial survey conducted between 2007 and 2010 by the National Coordinating Agency for Survey and Mapping (Bakorsurtanal), Indonesia has 13,466 islands. However, according to earlier survey in 2002 by National Institute of Aeronautics and Space (LAPAN), the Indonesian archipelago has 18,307 islands, and according to the CIA ''World Factbook'', there are 17,508 islands. The discrepancy of the numbers of Indonesian islands was because that the earlier surveys include "tidal islands"; s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
