As global warming progresses, storm and flood disasters caused by typhoons and torrential rains are becoming more serious. If we can change the intensity, timing, and range of these phenomena, we may be able to avoid direct damages or greatly reduce them. The goal of this project is to develop a method for optimizing control input locations (actuator locations) for large degree-of-freedom fields to improve the efficiency of weather control, and to demonstrate numerically the effectiveness of the method.
