Better yet - find a way to make waterskin impermeable to heat transfer, or create a biodegradeable insulating oil, and cut off the storm energy at its proximate source (its prior distal source being, of course, the sun which heats the ocean water). Or maybe, induce heat filtration properties into the tropical stratosphere above and in front of the storm to steal its sunshine and dampen it out.
