Hurricane simulation. This screenshot is from the award-winning simulation 'Towers in the Tempest', produced by NASA's Scientific Visualization Studio in 2007. Here, air rising on the edge of the low-pressure system that is the hurricane's eye (L), takes energy from warm ocean water through evaporation, releasing it at a height of around 15 kilometres as the condensation of clouds. The entire simulation shows the formation of a phenomenon known as a 'hot tower' that conveys energy rapidly to higher levels within the hurricane, intensifying its strength. The simulation was based on observations of Hurricane Bonnie using the Tropical Rainfall Measuring Mission (TRRM) spacecraft.
