Dynamics of cyclogenesis and propagation are poorly explained by current models and sources of energy enabling the growth of cyclonic systems into hurricanes has been incompletely identified. The contribution of the removal of water vapor from convection currents adds a useful component that explains the strong localized depressions that enable the continuity and growth of convective phenomena in depressionary events. Contrary to previous studies, the latent energy of condensation is not what is being considered here, but rather the rapid, localized drop in air pressure due to the elimination of the contribution of the partial pressure of water vapor as it is removed from the atmosphere. Condensation occurs in the convective column as it reaches an altitude where the temperature drops below the dew point temperature. The partial vacuum that results at this altitude further drives the convection, complementing the driving forces such as heat that may have initiated the convection at lower levels. Conversely, the evaporation of water at the surface increases the atmospheric pressure at ground level by adding the partial pressure of newly created water vapor to the surrounding air at this level. This additional pressure is immediately dissipated into the air column by diffusion of the air upwards and can therefore contribute to the formation of convective systems.
