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 ...

Maximum Sustained Wind
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a certain distance from the center, known as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above mean sea level, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery is often used to estimate the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, an ...

Blantyre
Blantyre is Malawi's centre of finance and commerce, and its second largest city, with a population of 800,264 . It is sometimes referred to as the commercial and industrial capital of Malawi as opposed to the political capital, Lilongwe. It is the capital of the country's Southern Region as well as the Blantyre District. History Blantyre was founded in 1876 through the missionary work of the Church of Scotland. It was named after Blantyre, South Lanarkshire, Scotland, birthplace of the explorer David Livingstone. The site was chosen by Henry Henderson, who was joined there on 23 October 1876 by Dr T. T. Macklin and others. Dr Macklin took over the leadership of the mission and began the work of building; but it was not until 1878 that the first ordained minister, Rev. Duff MacDonald, joined the mission. The original missionaries, for various reasons, faced local opposition and three of them were recalled. From 1881 to 1898, the mission was run by David Clement Scott, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malawi
Malawi, officially the Republic of Malawi, is a landlocked country in Southeastern Africa. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south, and southwest. Malawi spans over and has an estimated population of 21,240,689 (as of 2024). Lilongwe is its capital and largest city, while the next three largest cities are Blantyre, Mzuzu, and Zomba, the former capital. The part of Africa now known as Malawi was settled around the 10th century by the Akafula, also known as the Abathwa. Later, the Bantu groups came and drove out the Akafula and formed various kingdoms such as the Maravi and Nkhamanga kingdoms, among others that flourished from the 16th century. In 1891, the area was colonised by the British as the British Central African Protectorate, and it was renamed '' Nyasaland'' in 1907. In 1964, Nyasaland became an independent country as a Commonwealth realm under Prime Minister Hastings Banda, and was rena ...

Cyclone Cheneso
Tropical Cyclone Cheneso was a strong tropical cyclone that affected Madagascar in January 2023. The fourth tropical storm and fifth tropical cyclone of the 2022–23 South-West Indian Ocean cyclone season, Cheneso developed out of a zone of disturbed weather status which was first monitored at RSMC La Réunion on 17 January. Despite convection wrapping into the curved band pattern, the system formed into a tropical depression on 18 January. The depression strengthened into Severe Tropical Storm Cheneso on the following day. Cheneso made landfall over northern Madagascar and weakened into an inland depression, before emerging into the Mozambique Channel. Cheneso later strengthened into a tropical cyclone on 25 January. The system continued moving southeast, before transitioning into a post–tropical depression on 29 January. The National Office for Risk and Disaster Management (BNGRC) has reported 33 deaths and 20 missing. The agency reports a total 90,870 affected people, 34,100 ...

Cyclone Batsirai
Intense Tropical Cyclone Batsirai was a deadly tropical cyclone which heavily impacted Madagascar in February 2022, becoming the strongest tropical cyclone to strike Madagascar since Cyclone Enawo in 2017. It made landfall two weeks after Tropical Storm Ana brought deadly floods to the island country in late January. The second tropical disturbance, the first tropical cyclone, and the first intense tropical cyclone of the 2021–22 South-West Indian Ocean cyclone season, Batsirai originated from a tropical disturbance that was first noted on 24 January 2022. It fluctuated in intensity and became a moderate tropical storm on 27 January 2022, after which it unexpectedly rapidly intensified into an intense tropical cyclone. It then weakened and struggled to intensify through the coming days due to present wind shear and dry air, where it weakened after some time. Afterward, it entered much more favorable conditions, rapidly intensified yet again to a high-end Category 4 cyclone on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quelimane
Quelimane () is a seaport in Mozambique. It is the administrative Capital (political), capital of the Zambezia Province and the province's largest city, and stands from the mouth of the Rio dos Bons Sinais (or "River of the Good Signs"). The river was named when Vasco da Gama, on his way to India, reached it and saw "good signs" that he was on the right path. The town was the end point of David Livingstone's west-to-east crossing of south-central Africa in 1856. Portuguese is the official language of Mozambique, and many residents of the areas surrounding Quelimane speak Portuguese. The most common local language is Chuwabu language, Chuabo. Quelimane, along with much of Zambezia Province, is extremely prone to floods during Mozambique's rainy season. History Pre-colonial era The town originated as a Swahili people, Swahili trade centre, and then grew as a slavery, slave market of the Indian Ocean slave trade.

Landfall
Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there.' Tropical cyclone A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in a relatively strong tropical cyclone, this is when the center of its eye moves over land. This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall. Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains. These coupled with high surf can cause major beach erosion. When a tropical cyclone makes landfall, the eye usually closes in upon itself due to negative environmental factors over land, such as ...

Mascarene Islands
The Mascarene Islands (, ) or Mascarenes or Mascarenhas Archipelago is a group of islands in the Indian Ocean east of Madagascar consisting of islands belonging to the Republic of Mauritius as well as the French department of Réunion. Their name derives from the Portuguese navigator Pedro Mascarenhas, who first visited them in April 1512. The islands share a common geological origin beneath the Mascarene Plateau known as the Mauritia microcontinent which was a Precambrian microcontinent situated between India and Madagascar until their separation about 70 million years ago. They form a distinct ecoregion with unique biodiversity and endemism of flora and fauna. Geography The archipelago comprises three large islands, Mauritius, Réunion, and Rodrigues, plus a number of volcanic remnants in the tropics of the southwestern Indian Ocean, generally between 700 and 1,500 kilometres east of Madagascar. The terrain includes a variety of reefs, atolls, and small islands. They pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
