Why do some scientist think that gobal warming would increase the strength of an hurricanes?
Hurricanes get their energy from warm ocean water. Warmer water usually means more potential for hurricanes to form and gain strength. Warmer water resulting from global warming could therefore lead to stronger hurricanes. Some have suggested, however, that changes to other factors such as wind shear could negate the effects of warmer oceans on hurricanes.
How do hurricanes that strike Florida form?
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.
How can a hurricane strengthen over cold water?
A true hurricane cannot strength over cold water. However, hurricanes that move into colder environments can undergo a process called extratropical transition in which they lose tropical characteristics. After this is complete the storm is no longer a hurricane but is considered an extratropical cyclone. These storm systems gain their strength from temperature contrasts rather than warm water. A hurricane undergoing this transition brings tropical air into a cold environment, creating conditions ideal for a very powerful extratropical cyclone.
How does the amount of humidity effect a hurricane?
The more humid the air the more potential there is for a hurricane to gain strength. Hurricanes get their energy from the latent heat stored in the moisture of the air, which is released when that moisture condenses.
Why do hurricanes rapidly decline on reaching land?
Hurricanes rely on warm ocean water to maintain their strength. When they move over land, they lose this source of energy and quickly weaken. The friction from the land also disrupts the circular motion of the storm, causing it to break apart.
What do hurricanes need to gain strength?
The warmth of the ocean water (apex)
Why do most hurricanes move from east to west over tropical waters?
Most hurricanes move from east to west over tropical waters due to the prevailing easterly trade winds in the tropics. These winds push the storms westward across the warm waters, where they can gain strength and intensify. Additionally, the rotation of the Earth (Coriolis effect) causes the storms to curve as they move, typically following a westward path.
Why can't hurricanes hit Chicago?
Hurricanes usually form over warm ocean waters near the equator, where they gain strength and energy. As hurricanes move northward, they tend to weaken as they encounter colder waters and less favorable atmospheric conditions. Additionally, the direction of prevailing winds and air pressure systems over North America typically steer hurricanes away from the Midwest towards the Atlantic or Gulf Coast.

Do hurricanes gain energy?
Yes, hurricanes gain energy from warm ocean waters. As the warm air rises and condenses, it releases latent heat, which provides the energy needed to strengthen the storm. This process is what fuels the intensification of hurricanes.
Why are tropical cyclones never observed within about 5 north and south latitudes?
Tropical cyclones require warm ocean waters to form and strengthen. The area within about 5 degrees north and south of the equator, known as the intertropical convergence zone, typically has weak Coriolis forces and minimal variation in the Earth's rotation, which are both needed for cyclone development. This zone also experiences the influence of the doldrums, which inhibit the formation of the organized vertical structure needed for cyclones to develop.
How does the amount of humidity effect a hurricane?
The more humid the air the more potential there is for a hurricane to gain strength. Hurricanes get their energy from the latent heat stored in the moisture of the air, which is released when that moisture condenses.
Why do the hurricanes weaken as they move over land?
Hurricanes weaken over land because they lose their main source of energy, which is the warm ocean water that fuels their intensity. Additionally, the friction from the land surface disrupts the structure of the storm. As a result, the storm's winds diminish and the system breaks down.
