Abstract
The problem of the deformation due to the movement of hurricanes, typhoons or circular vortices are investigated theoretically and numerically in the baroclinic case, by making use of the parametric representations. According to them, the baroclinic correction in evaluating the deformation seems to be not so large as to upset the conclusions on the deformation problem that are deduced only form the barotropic treatments. Rather, it seems that the importance of the role of the vorticity gradient around the center, that has been left untouched so far, must be stressed more both in the barotropic and baroclinic cases.
