Tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls.

Tropical storm cyclones are very rare in the South Atlantic due to consistently strong wind shear and a weak Intertropical Convergence Zone.

Tropical storm cyclones draw in air from a large area and concentrate the water content of that air into precipitation over a much smaller area.

Tropical storm cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world.

Tropical storm cyclones tend to develop during the summer, but have been noted in nearly every month in most tropical cyclone basins.

Usually, an anticyclone in the upper layers of the troposphere above the Tropical storm must be present as well—for extremely low surface pressures to develop, air must be rising very rapidly in the eyewall of the Tropical storm, and an upper-level anticyclone helps channel this air away from the cyclone efficiently.

Tropical storm cyclones possess winds of different speeds at different heights.

Ten of these warning centres worldwide are designated as either a Regional Specialized Meteorological Centre or a Tropical storm Cyclone Warning Centre by the World Meteorological Organisation's tropical cyclone programme.

Tropical storm cyclones destroy agriculture, kill livestock, and prevent access to marketplaces for both buyers and sellers; both of these result in financial losses.

Tropical storm cyclones help maintain the global heat balance by moving warm, moist tropical air to the middle latitudes and polar regions, and by regulating the thermohaline circulation through upwelling.

Tropical storm cyclones are further influenced by the Atlantic Meridional Mode, the Quasi-biennial oscillation and the Madden–Julian oscillation.

In general, surface observations are available only if the Tropical storm is passing over an island or a coastal area, or if there is a nearby ship.

Tropical storm cyclones are tracked by weather satellites capturing visible and infrared images from space, usually at half-hour to quarter-hour intervals.

An extratropical cyclone is a storm that derives energy from horizontal temperature differences, which are typical in higher latitudes.
