From a nonhuman perspective, tropical cyclones are very important to the global climate system. Their primary purpose is to transport heat and moisture away from the equator, where there is a great imbalance due to the heating of the earth. Even after they have made landfall and weakened, often in the mid-latitudes, they continue to move poleward while transporting tremendous amounts of tropical moisture and latent heat. On a more local scale, tropical cyclones reshape the geology near the coast by eroding sand from the beach as well as offshore, rearranging coral, and changing dune configuration onshore. These changes are necessary for these dynamic systems to adapt and rejuvenate themselves.
