2022–23 South-West Indian Ocean Cyclone Season
The 2022–23 South-West Indian Ocean cyclone season was one of the costliest and deadliest South-West Indian cyclone seasons on record, mostly due to Cyclone Freddy. It officially began on 15 November 2022, and ended on 30 April 2023, with the exception for Mauritius and the Seychelles, for which it ended on 15 May 2023. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of 90°E and south of the Equator. However, tropical cyclones can form year-round, and all tropical cyclones that form between 1 July 2022 and 30 June 2023 will be part of the season. Tropical and subtropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion and unofficially by the Joint Typhoon Warning Center. The season was average in terms of the number of systems that formed, with nine systems becoming at least moderate tropical storms, and six reaching tropical cyclone stren ...

Cyclone Freddy
Very Intense Tropical Cyclone Freddy, also known as Severe Tropical Cyclone Freddy, was an exceptionally long-lived, powerful, and deadly tropical cyclone that traversed the southern Indian Ocean for more than five weeks in February and March 2023. Freddy was the longest-lasting tropical cyclone ever recorded worldwide, and produced the most accumulated cyclone energy—a metric used to measure the total energy generated by tropical cyclones—of any individual cyclone on record globally. Additionally, it is the third-deadliest tropical cyclone recorded in the Southern Hemisphere, only behind 2018–19 South-West Indian Ocean cyclone season, 2019's Cyclone Idai and the 1973 Flores cyclone. Freddy tropical cyclogenesis, originated from a tropical low that was located south of the Indonesian archipelago on 4 February 2023. As it traveled westward across the Indian Ocean, the storm quickly intensified, becoming a List of Category 4 Australian region severe tropical cyclones, Categ ...

Cyclone Darian
In meteorology, a cyclone () is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone). Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure. The largest low-pressure systems are polar vortices and extratropical cyclones of the largest scale (the synoptic scale). Warm-core cyclones such as tropical cyclones and subtropical cyclones also lie within the synoptic scale. Mesocyclones, tornadoes, and dust devils lie within the smaller mesoscale meteorology, mesoscale. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the tropical upper tropospheric trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars, Jupiter, and Neptune. Cyclogenesis is the process ...

Westerly Wind Burst
A westerly wind burst (WWB) or westerly wind event (WWE)https://glossary.ametsoc.org/wiki/Westerly_wind_burst is a phenomenon commonly associated with El Niño events, whereby the typical east-to-west trade winds across the equatorial Pacific shift to west-to-east. Definition A westerly wind burst is defined by Harrison and Vecchi (1997) as sustained winds of over a period of 5–20 days. However, no concrete definition has been determined, with Tziperman and Yu (2007) defining them as having winds of and lasting "at least a few days". On average, three of these events take place each year, but are significantly more common during El Niño years. They have been linked to various mesoscale phenomena, including tropical cyclones, mid-latitude cold surges, and the Madden–Julian oscillation. Their connection with Kelvin waves also indicate a connection with the onset of El Niño events, with every major occurrence since the 1950s featuring a westerly wind burst upon their ...

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 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 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-minute period. In the W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2010–11 South-West Indian Ocean Cyclone Season
The 2010–11 South-West Indian Ocean cyclone season was the least active cyclone season on record in the basin, tied with 1982–83, producing only three systems of gale intensity. This was due to cooler than normal water temperatures and the Walker circulation – a broad atmospheric circulation – causing unusually moist conditions in the eastern Indian Ocean and unusually dry conditions in the western Indian Ocean. The basin includes the waters of the ocean south of the equator and west of 90º E to the eastern coast of Africa. There were nine tropical or subtropical cyclones during the season, including five weak tropical disturbances or depressions, mostly in the northeastern portion of the basin or to the east of Madagascar. The first of these systems developed on 25 October 2010, which had its origins in the northeastern portion of the basin. On 29 November, the first named storm – Abele – also formed in the same area, strengthening to become one o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1982–83 South-West Indian Ocean Cyclone Season
The 1982–83 South-West Indian Ocean cyclone season was the least active cyclone season in the basin since 1961–1962. There were six systems that were named, although three of them – Arilisy, Clera, and Fely – failed to intensify beyond tropical depression status. No storms reached tropical cyclone status, according to the official warning agency for the basin, Météo-France, although the two strongest storms – Bemany and Elinah – peaked just below that intensity. The first named storm, Arilisy, formed on October 27, and dissipated without having affected land. However, the Joint Typhoon Warning Center (JTWC), which is an unofficial warning center for the basin, briefly tracked a tropical depression in July. The next storm was Bemany, which passed east of Mauritius near peak intensity in early December. Tropical Depression Clera existed briefly in the middle of September, and Tropical Storm Dadafy moved across the eastern portion of the basin in late December. Th ...

2018–19 South-West Indian Ocean Cyclone Season
The 2018–19 South-West Indian Ocean cyclone season was a record breaking and devastating season that was the most active season ever recorded in the basin. It is also the deadliest cyclone season recorded in the South-West Indian Ocean, surpassing the 1891–92 season in which the 1892 Mauritius cyclone devastated the island of Mauritius, and was the costliest South-West Indian Ocean season at the time until it was surpassed by the 2024-25 South-West Indian Ocean cyclone season, 2024-25 season. Most of the fatalities and damage came from Cyclone Idai. The season was an event of the annual cycle of tropical cyclone and subtropical cyclone formation in the South-West Indian Ocean basin. It officially began on 15 November 2018, and ended on 30 April 2019, except for Mauritius and the Seychelles, which it ended on 15 May 2019. These dates conventionally delimit the period of each year when most tropical and subtropical cyclones form in the basin, which is west of longitude, 90°E an ...
