Why do more hurricanes occur in america?

Answer 1

The region of the U.S. between the Rockies and the appalachians sees a high frequency of tornadoes because of its ideal climatic setup. In the spring, storm systems cause warm, moist air from the Gulf of Mexico to collide with cool air from Canada and sometimes dry air from the Rockies for events further west, resulting in the formation of strong thunderstorms. About a mile off the ground a layer of stable air holds thunderstorm activity back, allowing instability to build underneath it. As a result when the storm break through the cap the instability will be enormous, leading to explosively powerful thunderstorms. At the same time wind speed and direction varies with altitude, which sets these storms rotating and also strengthens the updraft. This rotation combined with strong thunderstorm updrafts can then produce tornadoes.

Additionally, the National Weather Service is very diligent in surveying areas hit by tornadoes, meaning that it records as many tornadoes as it can. Most countries do not have such agencies, and so many tornadoes that occur are never recorded.

Answer 2

The seasonal interaction of warm, moist air from the Gulf of Mexico, with cooler air from Canada, drier air from the Rockies, and wind shear form interactions between high and low altitude winds are relatively common in the central United States. These conditions can produce powerful rotating thunderstorm called supercells. These storms can produce large hail, strong straight line winds, and tornadoes/

Answer 3

They don't. However, American media sources give more coverage to the storms that hit the U.S. China, it seems, gets quite a few typhoons, which are what hurricanes are called in the western Pacific.

Answer 4

Hurricanes develop over warm tropical water. The United States is quite large, and bordered by 2 oceans and a gulf. It has 95,471 miles of shoreline. Smaller countries, such as France, would have much less coastline. France has about 2,000 miles worth, and it is further north where waters are cooler.

Answer 5

It is from a combination of factors. The most influential is because Canada is farther North and most hurricanes happen further South in the region of the US. The other major factor has to do with the wind currents and the Cariolus effect.

Answer 6

low pressure forms from Africa and moves west towards the u.s.
