Tropical Storm Irina
Severe Tropical Storm Irina was a large tropical cyclone that brought gusty winds and torrential rain across Madagascar, Mozambique, and South Africa. Irina is considered one of the most devastating systems of the 2011–12 season. Irina formed from a tropical wave that was located north of Madagascar. The disturbance continued to move south and became Irina on February 27. Irina moved parallel to the Madagascar coast, causing extreme flooding which claimed 77 lives. The system still has an unknown damage total. Meteorological history On 22 February, an area of disturbed weather formed in the South-West Indian Ocean. The system steadily strengthened into a low pressure area shortly afterwards. With favorable conditions, ample convection was able to wrap around the low level circulation center, which allowed the system to strengthen into a tropical depression, on 25 February. On 26 February, RSMC La Reunion upgraded the system to Moderate Tropical Storm Irina as it conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mozambique
Mozambique, officially the Republic of Mozambique, is a country located in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the south and southwest. The sovereign state is separated from the Comoros, Mayotte, and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and dialect. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of the Portuguese Empire, Portuguese, who began a gradual process of colonisation and settlement in 1505. After over four centuries of Portuguese Mozambique, Portuguese rule, Mozambique Mozambican War of Indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2011–12 South-West Indian Ocean Cyclone Season
The 2011–12 South-West Indian Ocean cyclone season was a slightly above average event in tropical cyclone formation. It began on November 15, 2011, and ended on April 30, 2012, with the exception for Mauritius and the Seychelles, for which it ended on May 15, 2012. These dates conventionally delimit the period of each year when most tropical cyclones form in the region; however, Severe Tropical Storm Kuena developed in early June, after the season had officially ended. The basin is defined as the area west of 90°E and south of the Equator in the Indian Ocean, which includes the waters around Madagascar westward to the east coast of Africa. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion. __TOC__ Timeline 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:01/12/2011 till:01/0 ...

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Tropical Wave
A tropical wave (also called easterly wave, tropical easterly wave, and African easterly wave), in and around the Atlantic Ocean, is a type of atmospheric trough, an elongated area of relatively low air pressure, oriented north to south, which moves from east to west across the tropics, causing areas of cloudiness and thunderstorms. Tropical waves form in the easterly flow along the equatorial side of the subtropical ridge or belt of high air pressure which lies north and south of the Intertropical Convergence Zone (ITCZ). Tropical waves are generally carried westward by the prevailing easterly winds along the tropics and subtropics near the equator. They can lead to the formation of tropical cyclones in the north Atlantic and northeastern Pacific basins. A tropical wave study is aided by Hovmöller diagrams, a graph of meteorological data. West-moving waves can also form from the tail end of frontal zones in the subtropics and tropics, and may be referred to as easterly ...

Subtropical Cyclone
A subtropical cyclone is a weather system that has some characteristics of both tropical cyclone, tropical and extratropical cyclones. As early as the 1950s, meteorologists were uncertain whether they should be characterized as Tropical cyclone, tropical or extratropical cyclones. They were officially recognized and titled by the National Hurricane Center in 1972. Beginning in 2002, subtropical cyclones began receiving names from the official tropical cyclone lists in the North Atlantic hurricane, North Atlantic basin. Subtropical cyclones are also recognized in the South-West Indian Ocean tropical cyclone, South-West Indian Ocean and South Atlantic tropical cyclone, South Atlantic basins. There are two definitions currently used for subtropical cyclones depending on their location. Across the north Atlantic and southwest Indian Ocean, they require some central Convectional Precipitation, convection fairly near the center surrounding a warming core existing in the mid-levels of ...

Gaza Province
Gaza is a province of Mozambique. It has an area of 75,709 km2 and a population of 1,422,460 (2017 census), which is the least populous of all the provinces of Mozambique. Xai-Xai is the capital of the province. Inhambane Province is to the east, Manica Province to the north, Maputo Province to the south, South Africa to the west, and Zimbabwe to the northwest. History The province gets its name from the Gaza Empire, named after the grandfather of the First Monarch of the Gaza Empire, Soshangane. His great-grandson, Ngungunhane, known as “Lion of Gaza” was the last emperor of the Gaza Empire and the final monarch of the Jamine dynasty. Portuguese emissaries attempted to have him sign treaties recognizing Portugal's sovereignty in the region in 1885. Ngungunhane, however, refused to sign these treaties. On November 7, 1895, a direct confrontation between the Portuguese and Ngungunhane's forces took place in Coolela, leading to Ngungunhane fleeing to Chaimite for ...

2006–07 South-West Indian Ocean Cyclone Season
The 2006–07 South-West Indian Ocean cyclone season featured the second-most intense tropical cyclones for a season in the tropical cyclone basin, only behind the 2018–19 season. The basin contains the waters of the Indian Ocean south of the equator and west of 90°E. Météo-France's meteorological office in Réunion (MFR), the official Regional Specialized Meteorological Center for the South-West Indian Ocean, tracked 15 tropical disturbances, of which eleven attained gale-force winds. The season began in October 2006 with a short-lived tropical disturbance, followed by Anita in November, which was the first named storm of the season. Cyclone Bondo was the first of six intense tropical cyclones, which took a rare track through the southern Seychelles before making landfall on northwest Madagascar, killing 11 people. Severe Tropical Storm Clovis lasted from December 2006 to January 2007; it struck eastern Madagascar, killing four people. In January 2007, Cyclone Do ...

Cyclone Ivan
Intense Tropical Cyclone Ivan was a powerful tropical cyclone that struck Madagascar in February 2008. Forming from a persistent area of convection on 7 February, Ivan initially tracked southeastward, before looping to the west-southwest. Encountering favourable conditions, it strengthened to attain peak winds on 17 February before striking northeastern Madagascar. It degenerated into a remnant low pressure area as it crossed the island, and briefly re-organized into a weak tropical depression before dissipating on 22 February. Ivan caused heavy damage in Madagascar, leaving severe flooding and wind damage. In Île Sainte-Marie, the worst hit area, 90% of the infrastructure was destroyed, and 70% of the structures were destroyed. On mainland Madagascar, over of cultivated crops were destroyed, leaving hundreds of families without food. In addition, severe flooding and high winds in Toamasina left the entire city without electricity or drinkable water. In all, over 330,000 ...

Cyclones In Madagascar
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 ...
