Hurricanes are
huge swirling storms with cloud systems typically larger than a state. Tropical cyclones, called hurricanes in
Earth's Western Hemisphere and
typhoons in the Eastern Hemisphere,
get their immense energy from warm evaporated ocean water. As this water vapor cools and
condenses, it heats the air,
lowers pressure and hence causes cooler air to come
swooshing in. Winds can reach over 250 kilometers per hour and become
very dangerous. Much remains unknown about
cyclones, including how they are
formed and the exact path they will take.
