Imagine the following scene. Along the west coast of Africa is a powerful air stream. At a certain point the coastline turns sharply to the right, but the stream continues its path in the same direction. In the open sea, he meets another air current that moves him across the path along the northern coast of Africa. Nord Stream begins to sag, feeling strong pressure from the outside. A southward flow, moving along the formed groove, begins to turn around and turn into an atmospheric vortex. Cyclone usually brings with it bad weather, as the atmospheric pressure inside it is lower than outside. He draws in the clouds. In an anticyclone the opposite. Pressure at its center is higher than the outside. Therefore, the clouds do not fall in the middle of the anticyclone. But it would be incorrect to think that in the entire region cyclone whole sky covered with clouds and go to continuous rains. If you look at the top of the cyclone, from space, it appears that the clouds inside the giant vortex is distributed in the form of elongated oval-shaped bands, which tend toward the center of the cyclone. These clouds are called zones of atmospheric fronts. On them you have read this book. Usually, the occurrence of a cyclone formed and others. There can be up to 5 vortices. The velocity of the cyclone on average 30 ... 40 miles per hour, and sometimes they are accelerated to 100 miles per hour. These vortices are so vast that often reach a diameter of 1500 ... 2000 kilometers.
