Abstract

Tracks of typhoons are modeled through nonlinear interactions of vortices between a typhoon and the background winds, i.e., easterly and westerly, of which velocity profiles along latitude are approximated with Gaussian. An intense vortex filament, representing a typhoon, redistributes vortex filaments embedded in the background winds which carry the typhoon. Starting in the easterly, a typhoon track is found to be going on westward, turning eastward, or gyrating around the easterly-westerly boundary, in response to variations of vortex intensities of easterly and westerly as well as of a typhoon itself.
