How Does a Hurricane Develope: Hurricanes occur basically in the wind zone over the water of the Atlantic or the eastern Pacific, with a water temperature of over 26.5 ° C. If a uniform temperature gradient to a certain altitude exceeds a certain degree, a tropical cyclone can develop. The water evaporates in large quantities and rises by convection. Condensation creates large clouds.

This condensation of huge water masses releases enormous amounts of energy (latent heat). The air inside the clouds is thereby heated up, expands and then rises further with the residual moisture which has not yet risen. Above the warm surface of the sea, a negative pressure is created and air is then drawn from the environment with a high water vapor content. This creates above the hurricane clouds a zone of very high air pressure, from which the air is redistributed in an opposite vortex (anticyclon).

However, the area covered by a hurricane is much too large to form a uniform, closed air package that rises as a whole. Typical for all tropical cyclones is therefore the formation of spiral rainbands, where thermal winds prevail, and intervening zones in which somewhat cooler and drier air sinks again – without rain. After-flowing moist air rises in the rainbows and supplies constantly water and energy. The air masses flowing into the ground are set in rotation by the Coriolis force, a large-surface vortex is formed.
