How do hurricanes that strike Florida form?

Answer 1

Hhurricanes do not form in Florida or Bermuda, though they do form in the Caribbean. Hurricanes belong to a class of storms called tropical cyclones. These storms deveelop over wamr ocean water and are fueled by the mositure that evaporate sfrom it. The Caribbean and tropical Atlantic form one of the primary basins for tropical cyclone formation. Global wind patterns make it so that many hurricanes follow a path that first goes west and then curves to the north. This puts Bermuda, Florida, and the islands of the Carribbean in the paths of many hurricanes.

Answer 2

The hurricanes that hit Florida form the same way as almost all other hurricanes. They start out as low pressure areas of showers and thunderstorms called tropical disturbances. The disturbance gains energy from the moisture, causing it to gain strength and deepen (i.e. the pressure decreases). The low pressure and thunderstorms draw in more moist air. This inflowing air beings to spiral into the disturbance as a result of the Coriolis Effect, a consequence of earth's spin. The spiraling air causes the disturbance to become more organized, which in turn allows it to strengthen more efficiently.

Once the system develops an identifiable circulation it is called a tropical depression. This is the weakest level of a tropical cyclone. As the depression strengthens its wind speed increases. When sustained winds reach 39 mph it becomes a tropical storm and is given a name. The strengthening storm continues to organize, developing spiral bands. When sustained winds reach at least 74 mph the storm is finally classified as a hurricane.

The disturbances that become Florida hurricanes often originate in Africa. Atlantic hurricanes that develop from these disturbances are called Cape Verde type hurricanes. The movement of these storms is largely dictated by the Azores High, a semi permanent high pressure system that creates a clockwise flow of air over the Atlantic. This creates a common path for Atlantic hurricanes in which they start out moving west and make a gradual turn to the north. Sometimes this directs storms straight into Florida.
