Resumen
Two numerical experiments were performed with a simple energy balance climate model. One is for a global ocean planet and the other one is for a wet land planet. It was found that the tropical rainbelt maximum migrates, for a land planet, about 30° in latitude, while for the ocean planet, it stays always near the equator. Because of this stationarity of the rainbelt in the ocean planet, a tropical desert is formed besides the extratropical desert, which forms both for land and ocean planet experiments.
