Different Names for Hurricanes. The scientific name for a hurricane is a tropical cyclone.
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm. And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes. Satellite data shows the heat and energy transfer in action. Notice how this hurricane leaves a trail of cooler water behind.
