Three-dimensional model of the atmosphere and the ocean in a typhoon zone

The sea surface temperature (SST), which largely governs the rates of surface evaporation, as well as the convective stability of the atmosphere, directly affects the intensity of the cyclonic circulation, especially during the early period of its development. On the other hand the friction of hurricane-strength winds against the ocean surface induces a significant rearrangement of the thermodynamic structure of its upper layer, so its surface temperature decreases. If a tropical cyclone remains stationary (or moves very slowly) for 1 to 2 days, then find that a, cyclonic circulation of synoptic scale is generated in the underlying ocean. This synoptic circulation, as well as the cyclone wake, persist for several weeks after the storm has passed. The decrease in the surface temperature of the sea under the cyclone may weaken the latter. This paper describes the results of calculations based on a model of an ocean-atmosphere system that involves the coupling of a three-dimensional model of evolution of a tropical cyclone with a nonlinear model of an integral ocean.
