NICOP - Dynamic Energy Efficiency in the Tropical

Abstract

Eliassen’s balanced vortex model offers a simple, fast and elegant way to explain tropical cyclone (TC) intensity and structure changes through diabatic heating and momemtum source/sink. We derive the dynamic energy efficiency of heat and of momentum in the Eliassen’s balanced vortex. The derivation is to write the energy conversion term between the available potential energy (APE) and kinetic energy (KE) as the product of the heat and momentum source/sink and the dynamic energy efficiency factors of heat and momentum. The dynamic energy efficiency is determined by solving the Eliassen’s transverse circulation equation with the radial temperature gradient on the right hand side of the equation
