 Super Hurricanes

For millennia, we saw the oceans as mysterious wellsprings of nature's power, capable of rising up and engulfing us. The history books are filled with stories of cities and towns caught off guard by the sudden onrush of a tropical storm.

We now see hurricanes, typhoons, and cyclones as the product of climate systems on a much larger scale... water and wind, oceans and land. They are fueled by heat from the sun, captured and stored in the upper layer of tropical oceans. The deeper and warmer this upper layer becomes, the stronger and longer lasting a hurricane can be.
