ON THE DYNAMICAL BASIS OF GEOSTRAPHIC MOTION IN TROPICS

Some conditions of dynamic contract of geostraphic motion in the tropical baroclinic atmosphere are given. The equation of dispassion of gravity-intertia wave and the equation of potential voticity time irrelevance are obtained. It is indicated that motions approach horizontal based on the right of Taylor-proudman theorem in tropics. The motions become horizontal and nondivergence but still are stratificative after geostraphic balance established.
