Tropical cyclones regularly affect the coastlines of most of Earth's major bodies of water along the Atlantic, Pacific, and Indian oceans. Also known as hurricanes, typhoons, or other names, tropical cyclones have caused significant destruction and loss of human life, resulting in about 2 million deaths since the 19th century.
Tropical Cyclones that develop within this basin generally affect countries to the west of the dateline, though during years of the warm phase of El Niño–Southern Oscillation cyclones have been known to develop to the east of the dateline near French Polynesia. On average the basin sees nine tropical cyclones annually with about half of them ...
A mature tropical cyclone can release heat at a rate upwards of 6×10 14 watts. [1] Tropical cyclones on the open sea cause large waves, heavy rain, and high winds, disrupting international shipping and, at times, causing shipwrecks. [2] Generally, after its passage, a tropical cyclone stirs up ocean water, lowering sea surface temperatures ...
The proportion of tropical cyclones reaching category four and five may increase by around 10% if global temperature rises are limited to 1.5C, increasing to 13% at 2C and 20% at 4C, the IPCC says ...
Post-tropical cyclone – a former tropical cyclone that no longer has enough tropical quantities to be considered a tropical cyclone. Post-tropical cyclones, such as remnant lows, no longer possess tropical quantities through either unfavorable conditions (e.g. increased wind shear) or land interaction.
Maps show the areas impacted by storm surge, rainfall levels and more as Helene, once a major hurricane and now a tropical storm, moves inland from Florida's Gulf Coast over Georgia.
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]

Super cyclonic storm is the highest category used by the India Meteorological Department (IMD) to classify tropical cyclones, within the North Indian Ocean tropical cyclone basin between the Malay Peninsula and the Arabian Peninsula.
