I., u For tropical‐cyclone‐scale vortices, the theory shows excellent agreement with equivalent numerical calculations for a period of one or two days. Until April 1991, it was thought that tropical cyclones did not develop within the South Atlantic. Both the intensity (i.e., 5-7 hPa) and the motion of the tropical cyclone were affected by the cooling of the sea surface (i.e., 3.5°-6°C) induced by the tropical cyclone.

Vulnerability to tropical cyclones: evidence from the april 1991 cyclone in coastal bangladesh. Given the relative lack of work on TCs in the region, it is important to investigate cases like Eline that have large rainfall impacts and unusual evolutions. Winds are often used to measure intensity as they commonly cause notable impacts over large areas, and most popular tropical cyclone scales are organized around sustained wind speeds. Predicting where they will form, where they will track, and how strong they will be is extremely important! Forming out of a large area of convection over the Bay of Bengal on April 24, the tropical cyclone initially developed gradually while meandering over the southern Bay of Bengal. 3.
