Why do hurricanes start in Africa and end in north America?

Answer 1

They don't ctually orginate in the Sahara, but rather the region to its south. During the summer, there is convergence of moist air, which leads to the formation of clusters of thunderstorms called tropical disturbances. These disturbance move west, out over the Atlantic Ocean. Here, they are fed by the moisture that evaporates from the warm water. If conditions are right, these disturbances will organize and strengthen, eventually becoming hurricanes. Many, but not all Atlantic hurricanes originate in this manner.

Answer 2

That is a common route for Atlantic hurricanes but not all hurricanes take it. These storms are known as Cape Verde type hurricane as they often start develop near the islands of that name. They start out as disorganized clusters of showers and thunderstorms with an area of low pressure. Wind patterns to the north and south in Africa give the system a slight twist which, in the long run helps it become a cyclone. The system is carried westward over the Atlantic Ocean by the trade winds. As the system, now called a tropical disturbance, is energized from the moisture evaporated off the warm water it strengthens are starts to organize. Eventually it develops a distinct circulation of wind, becoming a tropical depression, the weakest level of tropical cyclone. As it strengthens it may eventually reach hurricane strength as it continues westward. Many of these storms are strong when they reach North America as the waters along its southern shores are very warm.

Answer 3

A large area of warm water will produce a large amount of water vapor, leading the the development of warm moist air. The moisture in the air stores enormous amounts of energy in the form of latent heat. When low pressure moves into the area, the air rises and cools, . The mositure condenses to form rain andclouds, releasing its energy in the process. This is what powers a hurricane. The ocean is the only body of water large enough and deep enough to provide the necessary amount of moisture.

Answer 4

Tropical storms and hurricanes are basically heat engines, serving to move heat energy northward. The swirling winds are powered by warm air rising from warm ocean waters. The warmest waters are generally close to the equator, where any small instability can lower the central air pressure enough to initiate a circular wind flow. If the energy continues to accrue, and there is little wind shear at high altitudes, the storm can become self-sustaining and grow larger.

Once formed, tropical cyclones can remain coherent well into the higher latitudes.

Answer 5

Hurricanes start as tropical disturbances in the warm waters of the Atlantic Ocean, often forming off the west coast of Africa. As they move westward, they can develop into hurricanes due to the warm ocean waters and favorable atmospheric conditions. Many of these hurricanes eventually make landfall in North America, where they may weaken and dissipate.

Answer 6

Hurricanes form out in the Ocean; they do not come from Africa or any other land area.

Answer 7

The Atlantic Ocean
