Severe Hurricanes

How Hurricanes Form?

A hurricane forms when warm ocean water gives energy to winds that push humid air into the atmosphere.  Wind then blows outward above the storm allowing the air below to rise. Once this happens humid air rising makes the clouds of the storm(Convection)(When warm air rises because it is less dense than other air).  Then light winds around the storm steer the hurricane and allow it to grow.  To form a hurricane need a warm front(Warm air), extremely low pressure(Little to no sunshine), very warm temperatures, and it needs cumulonimbus clouds(Storm clouds).
