Tropical cyclogenesis is the development and strengthening of a
tropical cyclone in the
atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which mid-
latitude cyclogenesis occurs. Tropical cyclogenesis involves the development of a
warm-core cyclone, due to significant
convection in a favorable atmospheric environment. There are six main requirements for tropical cyclogenesis: sufficiently warm sea surface temperatures, atmospheric instability, high
humidity in the lower to middle levels of the
troposphere, enough
Coriolis force to develop a low pressure center, a preexisting low level focus or disturbance, and low vertical
wind shear.
