It has been considered that primary driving force of the Tsushima Warm Current (TWC) is the net pressure difference between the south and north straits, i.e., inflow-outflow dynamical process. On the other hand, the most intriguing aspect of surface circulation in the Japan Sea is the tremendous contrast between the incoming, TWC water and the cold water north of the polar front. So, the theory developed for inflow-outflow dynamics should be modified to include the thermo-dynamical process. To start a discussion for dynamics, we need to briefly review the scale of TWC system in space and in time. Next, I solved the heat equation containing the lateral heat transport from the East China Sea and sea surface cooling at the annual mean state in conjunction with the geostrophic equation of motion, and boldly predicted the TWC change caused by global warming.
