Cyclone Chido
Intense Tropical Cyclone Chido was a compact but very powerful, destructive, and deadly tropical cyclone which impacted Southeast Africa in December 2024. Chido, which means ''a desire'' in Shona language, Shona, was the third named storm and the second List of South-West Indian Ocean intense tropical cyclones, intense tropical cyclone of the 2024–25 South-West Indian Ocean cyclone season. It became the strongest tropical cyclone to affect Agaléga since Cyclone Andry in 1983, and the most powerful storm to strike Mayotte in at least 90 years. It is also the costliest tropical cyclone on record in the South-West Indian Ocean basin, surpassing Cyclone Idai of 2019. Chido originated from an elongated circulation that the Météo-France office in Réunion (RSMC La Réunion) began monitoring on 7 December, located east of Diego Garcia. In the post-storm analysis, it was indicated that the storm had already begun forming as a zone of disturbed weather on 5 December. On 11 December, ...

Diego Garcia
Diego Garcia is the largest island of the Chagos Archipelago. It has been used as a joint UK–U.S. military base since the 1970s, following the expulsion of the Chagossians by the UK government. The Chagos Islands are set to become a former British Overseas Territories, British overseas territory — a treaty to transfer sovereignty from the UK to Mauritius was signed on 22 May 2025, with a provision that the military base at the island would remain under British control for at least 99 years. Located just south of the equator in the central Indian Ocean, Diego Garcia lies east of Tanzania, east-southeast of Somalia, south of the Maldives, southwest of India, west-southwest of Sumatra, northwest of Australia, and northeast of Mauritius#Mauritius_Island, Mauritius Island. Diego Garcia is part of the Chagos–Laccadive Ridge, Chagos-Laccadive Ridge, an underwater mountain range that includes the Lakshadweep, the Maldives, and the other 60 small islands of the Chagos Archi ...

Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropics, tropical cyclogenesis occur are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm core, warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure area, low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in tropical cyclone basins, most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shanty Town
A shanty town, squatter area, squatter settlement, or squatter camp is a settlement of improvised buildings known as shanties or shacks, typically made of materials such as mud and wood, or from cheap building materials such as corrugated iron sheets. A typical shanty town is squatted and, at least initially, lacks adequate infrastructure, including proper sanitation, safe water supply, electricity and street drainage. Over time, shanty towns may develop their infrastructure and even change into middle class neighbourhoods. They can be small informal settlements or they can house millions of people. First used in North America to designate a shack, the term ''shanty'' is likely derived from French ''chantier'' (construction site and associated low-level workers' quarters), or alternatively from Scottish Gaelic ''sean'' () meaning 'old' and ''taigh'' () meaning 'house old. Globally, some of the largest shanty towns are Ciudad Neza in Mexico, Orangi in Pakistan and Dharavi i ... [...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 ...

Pemba, Mozambique
Pemba is a port city and district in Mozambique. It is the capital and largest city of the Cabo Delgado province and lies on a peninsula in Pemba Bay, the third largest in Africa. It is located northeast of Maputo, Mozambique's capital. Pemba is known as a prime destination for water sport and diving enthusiasts due to the bay and coral reef that surrounds the city. Whales, sunfish, sea turtles, and other various oceanic wildlife are known to frequent Pemba's coast. History There is no record of the town's existence or settlement before the 20th century, mainly serving as fishing ground for visiting Malagasy and Swahili fishermen. The first attempt at settlement was made by the Portuguese with a temporary fort that was dismantled after a few years in the late 1800s. The town was founded by the land-controlling and recently formed Niassa Company in 1898 as a small trading port. It was shortly renamed as Porto Amélia, after the last Queen of Portugal, Amélie of Orlé ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mozambique Channel
The Mozambique Channel (, , ) is an arm of the Indian Ocean located between the Southeast African countries of Madagascar and Mozambique. The channel is about long and across at its narrowest point, and reaches a depth of about off the coast of Mozambique. A warm current, the Mozambique Current, flows in a southward direction in the channel, leading into the Agulhas Current off the east coast of Southern Africa. Extent The International Hydrographic Organization (IHO) defines the limits of the Mozambique Channel as follows: ::''On the North.'' A line from the estuary of the River Rovuma () to Ras Habu, the northernmost point of Ile Grande Comore, the northernmost of the Comore (Comoro) Islands, to Cap d'Ambre (Cape Amber), the northern extremity of Madagascar (). ::''On the East.'' The west coast of Madagascar. ::''On the South.'' A line from Cap Sainte-Marie, the southern extremity of Madagascar to Ponto do Ouro on the mainland (). ::''On the West.'' The coast ...

Central Dense Overcast
The central dense overcast, or CDO, of a tropical cyclone or strong subtropical cyclone is the large central area of thunderstorms surrounding its circulation center, caused by the formation of its eyewall. It can be round, angular, oval, or irregular in shape. This feature shows up in tropical cyclones of tropical storm or hurricane strength. How far the center is embedded within the CDO, and the temperature difference between the cloud tops within the CDO and the cyclone's eye, can help determine a tropical cyclone's intensity with the Dvorak technique. Locating the center within the CDO can be a problem with strong tropical storms and minimal hurricanes as its location can be obscured by the CDO's high cloud canopy. This center location problem can be resolved through the use of microwave satellite imagery. After a cyclone strengthens to around hurricane intensity, an eye appears at the center of the CDO, defining its center of low pressure and its cyclonic wind field. Tropi ...

Minimum Central Pressure
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1,013.25 millibars, 760 mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
