In this video excerpt from NOVA: “Earth From Space,” data visualizations show what water vapor evaporating from the ocean's surface might look like if you could see it. Aqua, a NASA satellite, uses infrared wavelengths to monitor the oceans and the production of water vapor. The Sun's heat warms ocean water and creates water vapor through the process of evaporation. When water vapor condenses in the atmosphere, it releases heat that helps to fuel storms. Simulations show large cloud formations developing into a powerful hurricane that can impact life on Earth.
