Description
Multiscale interactions including boundary layer effects and moist convection are generally thought to be essential for the acceleration of tropical cyclones. Here we present an asymptotic analysis involving a triple-deck matched asymptotic expansion in the vertical and meanfield arguments for multiscale convection in an axisymmetric vortex. The resulting theory suggests transparent explanations of how various contributing processes can constructively interact to produce effective storm intensification.
