It turns out that Tropical Cyclones do provide a necessary function...wikipedia says: "They also carry heat energy away from the tropics and transport it toward temperate latitudes, which may play an important role in modulating regional and global climate." So I think the desired goal of the question (that we ought to destroy tropical cyclones) might not be a good goal for the health of the planet. Anyway, even if a cyclone is destroyed, the hot water it would have removed would still remain and would simply increase the chance for another cyclone to form.
