1999–2000 Australian Region Cyclone Season
The 1999–2000 Australian region cyclone season was a slightly above average tropical cyclone season. It ran from 1 November 1999 to 30 April 2000. The regional tropical cyclone operational plan also defines a "''tropical cyclone year''" separately from a "''tropical cyclone season''", with the "tropical cyclone year" for this season lasting from 1 July 1999 to 30 June 2000. Two of the most notable cyclones of the season were Steve and Rosita. Cyclone Steve transversed the entire Australian continent, and although a fairly weak cyclone, caused widespread flooding in Queensland, Northern Territory and Western Australia, while Cyclone Rosita made an almost direct hit on Broome as a severe Category 4 cyclone, devastating several remote stations and the town itself. Rosita surprised many residents of its arrival, as it made landfall very late in the season. __TOC__ Systems ImageSize = width:800 height:215 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 le ...

1997–98 Australian Region Cyclone Season
The 1997–98 Australian region cyclone season was a slightly below average tropical cyclone season. It ran from 1 November 1997 to 30 April 1998. 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 1997 to 30 June 1998. 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__ Systems 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:01/11/1997 till:01/05/1998 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/11/1997 Colors = id:canvas value:gray(0.88) id:GP value:red id:TL value:rgb(0.43,0.76,0.92 ...

Wind Shear
Wind shear (; also written 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low-pressure Area
In meteorology, a low-pressure area (LPA), low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. It is the opposite of a high-pressure area. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper troughs, which form half of a Rossby wave within the Westerlies (a trough with large wavelength that extends through the troposphere). * A ...

1999–2000 South-West Indian Ocean Cyclone Season
The 1999–2000 South-West Indian Ocean tropical cyclone season was the first on record in which two storms – Cyclone Leon–Eline, Leon–Eline and Cyclone Hudah, Hudah – struck Mozambique at tropical cyclone scales#South-West Indian Ocean, tropical cyclone intensity, or with maximum sustained winds of at least . The most notable storm of the season was Eline, which was the third longest-lasting storm on record in the basin. It lasted for 29 days while traversing the southern Indian Ocean, making the strongest landfall in decades along eastern Madagascar in late February. The storm was the first in a series of three storms that struck the country in early 2000, along with Gloria in March and Hudah in April. Collectively, the three storms killed at least 316 people. The season started on November 1, 1999, and ended for most of the basin on April 30, 2000; for Mauritius and the Seychelles, the season continued until May 15. These dates conventionally de ...
