Cyclone Ernie
Severe Tropical Cyclone Ernie was one of the quickest strengthening tropical cyclones on record. Ernie was the first Category 5 severe tropical cyclone in the Australian region since Cyclone Marcia in 2015, and also the strongest tropical cyclone in the Australian region since Cyclone Ita in 2014. Ernie developed from a tropical low into a cyclone south of Indonesia in the northeast Indian Ocean on 6 April 2017, and proceeded to intensify extremely rapidly to a Category 5 severe tropical cyclone. A few days later, on 10 April, the system was downgraded below cyclone intensity following a period of rapid weakening (though not nearly as rapid as its intensification), located southwest of its original position. Ernie had no known impacts on any land areas. Meteorological history On 5 April 2017, the Australian Bureau of Meteorology began monitoring a developing tropical low located in the northeast Indian Ocean, approximately east of Christmas Island. The system had bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ridge (meteorology)
A ridge or barometric ridge is a term in meteorology describing an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. It is associated with an area of maximum anticyclonic curvature of wind flow. The ridge originates in the center of an anticyclone and sandwiched between two low-pressure areas, and the locus of the maximum curvature is called the ''ridge line''. This phenomenon is the opposite of a trough. Description Ridges can be represented in two ways: * On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the ridge. * In upper-air maps, geopotential height isohypses form similar contours where the maximum defines the ridge. Related weather Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: *ahead of an upper-ridge, the airflow that comes from the polar regi ...

Mozambique Channel
The Mozambique Channel (french: Canal du Mozambique, mg, Lakandranon'i Mozambika, pt, Canal de Moçambique) is an arm of the Indian Ocean located between the Southeast African countries of Madagascar and Mozambique. The channel is about long and across at its narrowest point, and reaches a depth of about off the coast of Mozambique. A warm current, the Mozambique Current, flows in a southward direction in the channel, leading into the Agulhas Current off the east coast of Southern Africa. Extent The International Hydrographic Organization (IHO) defines the limits of the Mozambique Channel as follows: ::''On the North.'' A line from the estuary of the River Rovuma () to Ras Habu, the northernmost point of Ile Grande Comore, the northernmost of the Comore (Comoro) Islands, to Cap d'Ambre (Cape Amber), the northern extremity of Madagascar (). ::''On the East.''

Cyclone Hellen
Very Intense Tropical Cyclone Hellen of March 2014 was one of the most powerful tropical cyclones in the Mozambique Channel on record, as well as the most intense of the 2013–14 South-West Indian Ocean cyclone season. Hellen formed on March 26 in the northern portion of the channel, and the storm brought rainfall to coastal Mozambique while in its formative stages. While moving southeastward, it developed an organized area of convection over the center of circulation. Warm waters allowed Hellen to rapidly intensify while passing south of the Comoros, with a well-defined eye forming in the middle of the thunderstorms. The cyclone attained peak intensity March 30, with maximum sustained winds estimated 230 km/h (145 mph) according to the Regional Specialized Meteorological Center, Météo-France in La Réunion. Subsequently, Hellen weakened quickly due to dry air and land interaction with Madagascar, and the storm's eye dissipated. On March 31, the stor ...

Cyclone Gwenda
Severe Tropical Cyclone Gwenda is tied with Cyclone Inigo as the most intense Australian tropical cyclone on record (with the possible exception of Cyclone Mahina), with a barometric pressure of 900 hPa (mbar) and was the most intense storm worldwide in 1999. Forming out of a tropical disturbance over the Arafura Sea on 2 April 1999, the precursor to Gwenda tracked slowly westward and gradually became more organised. On 4 April, the system developed into a Category 1 cyclone and was named Gwenda. It began to undergo explosive intensification the following day, and in a 30-hour span ending early on 7 April, the storm's maximum 10-minute sustained wind speed increased from to and its barometric pressure decreased to 900 hPa (mbar). The Joint Typhoon Warning Center reported that the storm had peaked as a high-end Category 4 equivalent on the Saffir–Simpson hurricane scale. Increasing wind shear and an acceleration in forward speed caused Gwenda to quickly weaken. Les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Gillian
Severe Tropical Cyclone Gillian was the second most powerful of the 2013–14 Australian region cyclone season and the strongest in the basin in four years. It developed on 8 March, 2014, in the Gulf of Carpentaria offshore northern Australia. It drifted southeastward, moving over northwestern Queensland on 10 March as a weak tropical cyclone, and subsequently turned to the southwest and later to the west. Unfavourable wind shear, land interaction, and dry air prevented much restrengthening, and for several days Gillian was a weak low pressure area, tropical low. The storm moved northward and curved westward around the Top End of northwestern Australia, and subsequently moved across several islands in Indonesia, first Timor on 18 March. On 21 March, Gillian again became a tropical cyclone as it moved away from Indonesia. On the next day, it passed just southeast of Christmas Island as an intensifying storm, and subsequently Gillian underwent rapid deepening. On ...
