Unformatted text preview: the way-cyclones-tropical cyclones occur in tropical regions. Biggest ones are hurricanes, typhoons- different names for the same thing-Giant heat engines, fueled by the storage and release of oceanic latent heat by evaporation and condensation-formed by moving heat in the ocean around by condensation and evaporation and are self sustainging as long as they are over warm areas in ocean, loose strength if not over warm water in ocean-Masses of humid, warm rotating air-form within one air mass over ocean between 10 degrees and 25 degrees latitude-born as tropical depressions, low pressure zones in trade winds (winds from Africa to middle latitudes)-must move over water of >26 degrees c, 79 degrees F= pretty warm water-circular winds begin as warm air rises-wind speed <61 km/hr-in Hadley cells-never on equator-become tropical storms if wind speed < 120 km/hr-become hurricanes, typhoons, tropical cyclones if wind speed exceeds 120 km/hr...
