Tropical Cyclone Weakening Deep Water Drawing Column

Papers discussing artificial ocean cooling to weaken tropical cyclones are published. Cooling sea surface temperatures by 2.5ºC would weaken and reduce the damage of a tropical cyclone but lack a practical method. This is a cost and logistic capable autonomous solution.

The ocean thermocline provides a source of cold water. Storm waves provide energy.
