Abstract: piral cloud bands dominate tropical cyclones? appearance in satellite and radar images. It is generally accepted that at least some of them are vortex Rossby waves that propagate on the radial gradient of mean-flow-relative ...

Abstract: eta, the meridional gradient of planetary vorticity, causes tropical cyclones to propagate poleward and westward at approximately 2 m s?1. In a previous shallow-water linear model, the simulated vortex accelerated without ...
