Cyclone Freddy (2009)
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 is both the longest-lasting and highest-ACE-producing tropical cyclone ever recorded worldwide, traveling across the southern Indian Ocean, Mozambique, and Madagascar for 37 days and producing 87.01 units of ACE. Additionally, it is the third-deadliest tropical cyclone recorded in the Southern Hemisphere, only behind 2019's Cyclone Idai and the 1973 Flores cyclone. Freddy was the fourth named storm of the 2022–23 Australian region cyclone season, and the second very intense tropical cyclone of the 2022–23 South-West Indian Ocean cyclone season. Freddy first developed as a disturbance on 5 February 2023. While in the Australian region cyclone basin, the storm quickly intensified and became a Category 4 severe tropical cy ...

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] |
Blantyre
Blantyre () is Malawi's centre of finance and commerce, and its second largest city, with an enumerated 800,264 inhabitants . It is sometimes referred to as the commercial and industrial capital of Malawi as opposed to the political capital, Lilongwe.

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, 34,10 ...

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 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").

Maximum Sustained Winds
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 distance defined 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 the Earth's surface, 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 determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can ...
