Abstract: A method and apparatus for inhibiting or weakening the development of tropical cyclones by detecting the onset of tropical cyclonic activity using at least one storm tracking weather satellite and using at least one submerged modified nuclear powered submarine to pump cool subsurface water to cool the surface water in the area of such activity. The method and apparatus contemplate moving the submarine with the movement of the tropical cyclone as tracked by satellite with the objective that cooling activity is optimally positioned and unrelenting.

Abstract: A method and system for inhibiting or weakening the formation of hurricanes, by detecting the onset of a hurricane in a region of open water and immediately cooling the surface water in the open water region. In the decribed preferred embodiments, the surface water is cooled by using one or more nuclear-powered submarines to pump cooler water at a depth in the open water region to the surface of the open water region.
