Tropical Storm Cyprien
Severe Tropical Storm Cyprien (JTWC designation: ''08S'') was a short-lived tropical cyclone that caused minor damage in Madagascar. Forming on December 30, 2001, Cyprien quickly strengthened in a slightly favorable environment. By January 2, the storm attained its peak intensity with winds of 100 km/h (65 mph) according to Météo-France and 95 km/h (60 mph) according to the Joint Typhoon Warning Center. Later that day the storm made landfall in Morombe, at a weaker intensity, and dissipated early on January 3. Throughout the affected areas, Cyprien destroyed 957 structures, leaving 1.16 billion Malagasy franc (2002 MGF; US$181,000) in damages. No fatalities were reported; however two people were listed as missing. Meteorological history On December 26, a cold front exited Mozambique in southeastern Africa into the Mozambique channel. Upon reaching open waters, the front developed an area of convection and later a circulation just inland fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Subtropical Cyclone
A subtropical cyclone is a weather system that has some characteristics of both tropical cyclone, tropical and an extratropical cyclone. As early as the 1950s, meteorologists were uncertain whether they should be characterized as Tropical cyclone, tropical or Extratropical cyclone, extratropical cyclones. They were officially recognized and titled by the National Hurricane Center in 1972. Beginning in 2002, subtropical cyclones received names from the official tropical cyclone lists in the North Atlantic hurricane, North Atlantic, 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 the troposphere. Across the eastern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclones In 2002
Tropical cyclones in 2002 were spread out across seven different areas called basins. To date, 123 tropical cyclones formed in 2002. 80 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC). The strongest system was Cyclone Zoe, with a central pressure of . Zoe was also the second-most intense system before striking Fiji. The costliest and deadliest tropical cyclone of the year was Typhoon Rusa. Rusa killed 233 in South Korea and causing $4.2 billion (2002 USD) in damages. 26 Category 3 tropical cyclones, including eight Category 5 tropical cyclones formed in 2002. Tropical cyclone activity in each basin is under the authority of an RSMC. The National Hurricane Center (NHC) is responsible for tropical cyclones in the North Atlantic and East Pacific. The Central Pacific Hurricane Center (CPHC) is responsible for tropical cyclones in the Central Pacific. Both the NHC and CPHC are subdivisions of t ...

Cholera
Cholera is an infection of the small intestine by some strains of the bacterium ''Vibrio cholerae''. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish. Symptoms start two hours to five days after exposure. Cholera is caused by a number of types of ''Vibrio cholerae'', with some types producing more severe disease than others. It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked shellfish is a common source. Humans are the only known host for the bacteria. Risk factors for the disease include poor sanitation, not enough clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarrhea
Diarrhea, also spelled diarrhoea, is the condition of having at least three loose, liquid, or watery bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. The most common cause is an infection of the intestines due to either a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea are: short duration watery diarrhea, short duration bloody diarrhea, and persistent diarrhea (lasting more than two weeks, w ...

Government Of Madagascar
Politics of Madagascar takes place in a framework of a semi-presidential representative democratic republic, whereby the President of Madagascar is head of state and the Prime Minister of Madagascar is head of government, and of a pluriform multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the Senate and the National Assembly. The Judiciary is independent of the executive and the legislature. Political history Madagascar's first President, Philibert Tsiranana, was elected when his Social Democratic Party gained power at independence in 1960 and was reelected without opposition in March 1972. However, he resigned only 2 months later in response to massive anti-government demonstrations. The unrest continued, and Tsiranana's successor, Gen. Gabriel Ramanantsoa, resigned on February 5, 1975, handing over executive power to Lt. Col. Richard Ratsimandrava, who was assassinated 6 days later. A provisional milita ...

Morondava
Morondava (, from mg, morona lava "long coast") is a city located in Menabe Region, of which it is the capital, in Madagascar. It is located in the delta of the Morandava River at . Its population as of the 2018 census, was 53,510. Population The predominant tribe is the Sakalava. But there are also a few Betsileo, Tsimihety, Merina, Makoa as well as Europeans. Transportation Air Madagascar has regular scheduled flights to Morondava Airport. The main road to town has been renovated recently. With the new road established, a trip from Antananarivo to Morondava by taxi-brousse takes approximately 12 hours. Pirogues are consequently a popular mode of transport used to ferry people and goods along the coast, especially to Morombe. Roads * RN 34 to Ivato, Ambositra and Antsirabe. * RN 8 to Belo-sur-Tsiribihina. Ecology The city is famous amongst other things for the spectacular Avenue of Baobabs nearby at . These giant baobab trees are an 800-year-old legacy of the dense tropic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beira, Mozambique
Beira is the capital and largest city of Sofala Province, where the Pungwe River meets the Indian Ocean, in the central region of Mozambique. It is the fourth-largest city by population in Mozambique, after Maputo, Matola and Nampula. Beira had a population of 397,368 in 1997, which grew to 530,604 in 2019. A coastal city, it holds the regionally significant Port of Beira, which acts as a gateway for both the central interior portion of the country as well as the land-locked nations of Zimbabwe, Zambia and Malawi. Originally called Chiveve after a local river, it was renamed Beira to honour the Portuguese Crown prince Dom Luís Filipe (titled Prince of Beira, itself referring to the traditional Portuguese province of Beira), who had visited Mozambique in the early 1900s. It was first developed by the Portuguese Mozambique Company in the 19th century, supplanting Sofala as the country's main port. It was then directly developed by the Portuguese colonial government from 1947 until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westerlies
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes and trend towards the poles and steer extratropical cyclones in this general manner. Tropical cyclones which cross the subtropical ridge axis into the westerlies recurve due to the increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere. The westerlies are strongest in the winter hemisphere and times when the pressure is lower over the poles, while they are weakest in the summer hemisphere and when pressures are higher over the poles. The westerlies are particularly strong, especially in the Southern Hemisphere (called also 'Brave West winds' at striking Chile, Tasmania and New Zealand), in areas where land is absent, because land amplifies the flow pattern, ...

Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocean ...
