Heat generated near ground is diffusing into atomosphere and make some thermal environment as heat-island is found in a urbanized area by decreasing cooling ability and the great heat generation in comparison with those of the green belt. In this paper, fluid flow equations are theoretically investigated for this problem, and numerical methodlis used with a computer for a solution of finite defference approximation to the primitive equations of thermal diffusion and atomosphere motion caused by the heat-island in time dependent three-dimensional. Thermal environment, which is represented by temperature distribution and wind velocity variations caused by the heat-island, is described for an example of a small town and the out-skirts.
