Hurricanes are subdivided into tropical and extratropical at their place of origin. Tropical hurricanes often divided into hurricanes, emerging over the Atlantic ocean and the Pacific. The latter are called typhoons.

Hurricane (115-140)

Strong hurricane (140-170)

Violent hurricane (from 170)

The strength of a hurricane is determined by the Saffir-Simpson scale. It is used since 1973. Based on wind speed and includes an assessment of storm waves in each of 5 categories.

Hurricanes are formed in tropical latitudes over the ocean. The farther from the equator, the less of a chance to meet with the hurricane. The formation of a hurricane due to the following reasons:

the difference in values of atmospheric pressure;

the difference in temperatures of the upper and lower layers of the atmosphere;

the force of the rotation of the Earth.

To cause a hurricane, the water temperature rises to a minimum of 27°C. the Hurricane is caused when warm and moist air coming into contact with the water of the ocean or sea, and begins to climb. Reaching great heights, it condenseries, releasing heat, which causes a to rise and condense other masses of hot air.

A chain reaction. Meanwhile, the streams of air begin to rotate in a counterclockwise direction (clockwise in the southern hemisphere) due to the rotation of the Earth dragging the clouds. When the wind speed reaches 110-130 km/h, it becomes a hurricane. Hurricanes in the Northern hemisphere because of the rotation of the Earth moving West from Africa towards America).
