Downloaded from hlayiso.com Geograpny NSC 4.2 Refer to Tropical cyclone Batsirai. — Cyclone Batsirai Sous Metea Fane Intense Tropical Cyclone Batsirai was a deadly tropical cyclone which heavily impacted Madagascar in February 2022. Tropical Cyclone Batsirai swept over the Indian Ocean and into central and southern Madagascar on February 5-6, 2022, bringing torrential rain, flooding, and high winds of about 230 km per hour, bringing heavy impacts and majorly disrupting power and communication throughout the affected areas. 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. Afterward, it entered much more favorable conditions, rapidly intensified yet again to a high-end Category 4 cyclone on the Saffir-~Simpson scale while moving towards Madagascar 5 February. After the storm passed, thousands of people evacuated to temporary shelters. Batsirai has left at least 121 people dead, 112,000 displaced, and 124,000 homes affected. en.wikipedia.org/wiki/Cyclone_ Batsirai ee aan 1.2.1 What do you understand by the term category 4 tropical cyclone?
