Cyclones or Hurricanes
:
The cyclone is a swirling cloudy mass which turn around a center of low pressure (the eye). It occurs in the medium of the Atlantic in calm water, of a temperature > to 27°. It moves like a spinning top at the speed of 30 km/h, and is accompanied by very strong precipitations. The tide which it causes raises the sea level of 6 or 7 meters. Its energy power is comparable with the explosion of 5 nuclear bombs a second.

Canadian says thank to him ! :
The cyclone it is a valve of safety (like that of your pressure-cooker). It evacuates towards north the heat of the equator.
With your anemometer, measure the force of the cyclones.
