Abstract: A method for hurricane prevention by cooling the surface of the ocean water in the path of a tropical cyclone. This method is achieved by displacing the warmer surface water with the cooler water below it. The method involves using a surface vessel, such as a ship, in a region of open water to dissipate or weaken tropical cyclones by positioning the surface vessel in a path of travel of a tropical cyclone. The surface vessel is equipped with a redistribution device to collect warm surface water as the surface vessel is propelled through open water, and the warm water is diverted beneath its natural stratification level and replaced with cooler water along the surface of the open water.
