ON THE INFLUENCE OF RELEASED LATENT HEAT ON CYCLONE DEVELOPMENT
Abstract
The influences of release of latent heat of vaporization on vertical motion, production of kinetic energy, and development of low-level vorticity were investigated. The vertical motion was obtained by solving the customary (diagnostic) omega-equation, making allowance for horizontal variations of the static stability. Numerical solutions, with and without inclusion of released latent heat, were used to obtain ageostrophic wind components and their effect upon the production of kinetic energy and vorticity. The following results emerged: (1) the influence of released latent heat was of the same order of magnitude as the effect of dry adiabatic circulations; (2) to the amplification of the vertical motions that resulted from released latent heat corresponded intensification of the low-level convergence and high-level divergence; (3) the ageostrophic winds associated with these fields of convergence and divergence had components toward lower pressure, thus giving positive contributions to the production of kinetic energy both at low and at high levels; and (4) the computed rate of production of low-level vorticity exceeded the observed rate, and evidence suggests that frictional effects may be important.
