1997 Mozambique Floods
Throughout the month of February 1997, as a consequence of an active Intertropical Convergence Zone (ITCZ) tropical cyclogenesis was quite common over the southern Indian Ocean, and especially the Mozambique Channel. Two storms in particular, Cyclone Josie and Tropical Storm Lisette formed in the Channel and inundated much of Mozambique. Affecting a country already inundated by Cyclone Josie earlier in the year, Lisette brought additional flooding to the nation. The Nampula Province in Mozambique was severely damaged by the storm, where many roads were damaged. Effects from the system spread as far north as northern Mozambique. Overall, 87 people died while 80,000 others were directly affected. Meteorological history In late January into February 1997, the ITCZ produced areas of convection around the northern tip of Madagascar. One such convective system from spawned a low pressure area between Tromelin island and Agaléga, which initially was still located within the I ...

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern 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 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. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. 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 language. 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 t ...

Convection
Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed. Convection may also take place in soft solids or mixtures where particles can flow. Convective flow may be transient (such as when a multiphase mixture of oil and water separates) or steady state (see Convection cell). The convection may be due to gravitational, electromagnetic or fictitious body forces. Heat transfer by natural convection plays a role in the structure of Earth's atmosphere, its oceans, and its mantle. Discrete convective cells in the atmosphere can be identified by clouds, with stronger convection resulting in thunderstorms. Natural convection also plays a role in stellar physics. Convection is often categorised or d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclone Filao
Tropical Cyclone Filao was a moderately intense tropical cyclone that caused widespread flooding in Mozambique in 1988. First classified as a tropical depression north of Madagascar, the system moved southwest, crossing the northern part of the nation before entering the Mozambique Channel on 27 February, where it began to deepen. Later that day, the depression was upgraded into a moderate tropical storm. Two days later, Filao attained severe tropical storm intensity as it began to stall. On 1 March, the storm reached cyclone intensity just before turning west. Later that day, Filao attained peak intensity, with winds of and a minimum barometric pressure of 954 mbar (hPa); 28.17 inHg. Within 24 hours, however, the system moved ashore near Quelimane in Central Mozambique, and several hours later, Filao dissipated inland. Cyclone Filao killed 100 people in Mozambique, primarily in rural areas. Damage was heaviest in Quelimane, where wind gusts reached and rainfal ...

Government Of South Africa
The Republic of South Africa is a parliamentary republic with three-tier system of government and an independent judiciary, operating in a parliamentary system. Legislative authority is held by the Parliament of South Africa. Executive authority is vested in the President of South Africa who is head of state and head of government, and his Cabinet. The President is elected by the Parliament to serve a fixed term. South Africa's government differs greatly from those of other Commonwealth nations. The national, provincial and local levels of government all have legislative and executive authority in their own spheres, and are defined in the South African Constitution as "distinctive, interdependent and interrelated". Operating at both national and provincial levels ("spheres") are advisory bodies drawn from South Africa's traditional leaders. It is a stated intention in the Constitution that the country be run on a system of co-operative governance. The national government is c ...

Sooty Tern
The sooty tern (''Onychoprion fuscatus'') is a seabird in the family Laridae. It is a bird of the tropical oceans, returning to land only to breed on islands throughout the equatorial zone. Taxonomy The sooty tern was described by Carl Linnaeus in 1766 as ''Sterna fuscata'', bearing this name for many years until the genus ''Sterna'' was split up. It is now known as ''Onychoprion fuscatus''. The genus name is from ancient Greek , "claw" or "nail", and , "saw". The specific ''fuscatus'' is Latin for "dark". Colloquially, it is known as the wideawake tern or just wideawake. This refers to the incessant calls produced by a colony of these birds, as does the Hawaiian name ''ʻewa ʻewa'' which roughly means "cacophony". In most of Polynesia its name is ''manutara'' or similar – literally "tern-bird", though it might be better rendered in English as "the tern" or "common tern". This refers to the fact that wherever Polynesian seafarers went on their long voyages, they usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Prediction Center
The Climate Prediction Center (CPC) is a United States federal agency that is one of the National Centers for Environmental Prediction, which are a part of the National Oceanic and Atmospheric Administration's National Weather Service. CPC is headquartered in College Park, Maryland. Its roots trace back to the climatological work of Thomas Jefferson, with the United States Army Signal Corp taking over responsibility of the climate program in the late 19th century. Once it became part of the United States Weather Bureau, it was known as the Weather Bureau Climate and Crop Services. From 1957 through 1966, the United States Weather Bureau's Office of Climatology, located in Washington, D.C., and then Suitland, Maryland, published the Mariners Weather Log publication. Late in the 20th century, it was known as the Climate Analysis Center for a time, before evolving into CPC in 1995. CPC issues climate forecasts valid for weeks and months in advance. History The roots of modern cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inhambane Province
Inhambane is a province of Mozambique located on the coast in the southern part of the country. It has an area of 68,615 km2 and a population of 1,488,676 (2017 census). The provincial capital is also called Inhambane. The climate is tropical throughout, more humid along the coast and dryer inland. The coast has a number of mangrove swamps. The town of Inhambane existed in the 10th century, and was the southernmost port used by Arabs for slave trading. The region was visited by Vasco da Gama in 1498, who claimed Inhambane Bay for Portugal. The Portuguese established a trading post at Inhambane in 1534. The province is the second largest grower of cashews (after Nampula), and also produces coconut and citrus fruit (inspiring Mozambique's most famous poet Craveirinha to write of "The Tasty Tangerines of Inhambane"). The long coastline supports much fishing. The Inhambane Bay area is of some interest for tourism, with a number of beaches, and one of the last remaining po ...

Sofala Province
Sofala is a province of Mozambique. It has a population of 2,259,248 (2017 census). Beira is the capital of the province, named for the ruined port of Sofala which is to the south. History Portuguese landholder and imperialist Joaquim Carlos Paiva de Andrada established a base at the river mouth at what is now Beira in 1884. Sofala Province is one of the strongholds of the RENAMO. In late 1978 RENAMO guerrillas were "ranging into Sofala Province and launching attacks along the Beira–Chimoio road and rail line, the Dondo–Inhaminga corridor". Some of the more scarcely populated areas of the province are affected by landmines; defensive rings around villages were still common in some rural areas according to mid 1990s reports by Oxfam. In March 2019, the province was severely affected by Cyclone Idai, with its capital city of Beira being largely destroyed. The flooding resulting from this storm was widespread throughout the province and the rest of Central Mozambique. De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, 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 referred to by different names, including 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, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

Zimbabwe
Zimbabwe (), officially the Republic of Zimbabwe, is a landlocked country located in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Botswana to the south-west, Zambia to the north, and Mozambique to the east. The capital and largest city is Harare. The second largest city is Bulawayo. A country of roughly 15 million people, Zimbabwe has 16 official languages, with English, Shona language, Shona, and Northern Ndebele language, Ndebele the most common. Beginning in the 9th century, during its late Iron Age, the Bantu peoples, Bantu people (who would become the ethnic Shona people, Shona) built the city-state of Great Zimbabwe which became one of the major African trade centres by the 11th century, controlling the gold, ivory and copper trades with the Swahili coast, which were connected to Arab and Indian states. By the mid 15th century, the city-state had been abandoned. From there, the Kingdom of Zimbabwe was established, fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
