Abstract : A theoretical analysis has been conducted of the vortical cloud patterns on the leeward side of islands recently observed by Tiro satellites. A plausible theory for these cloud patterns is advanced. The disturbance created by a flat island will be replaced by that of a horseshoe vortex and its image. The deflection of the trailing vortex lines is obtained explicitly. The location of the observed vortex-like cloud is then interpreted as the intersection of the deflected trailing vortex line with the inversion level. Another plausible theory on the vortex cloud patterns is also presented, together with its shortcomings. An outline of the procedure of the analytical solution of the lifetime of a viscous vortex in a non-uniform stream is also presented. (Author)
