How does a hurricane hold so much water?
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. … And the warmer the water, the more moisture is in the air. And that could mean bigger and stronger hurricanes.
Why do tropical storms bring heavy rain?
As the air continues to rise quickly it draws more warm moist air up from above the ocean leading to strong winds. The rapidly rising warm air spirals upwards, cools, condenses and large cumulonimbus clouds form. These clouds form the eye wall of the cyclone and produce heavy rainfall.
