Atmospheric circulation is a large-scale movement of masses of air. The origin of these processes is the sun's radiation. The sun waves radiate the short-wave radiation. The earth absorbs only a part of this energy. The other part is radiated back to the atmosphere and to the universe. The back radiation is long-waved. The thermal energy is distributed thanks to the circulation of the air on the surface of the earth.
The details of circulation vary from year to year, but the basic climatologic structure is almost constant. We recognize 3 cells: the Hadley cell, the Ferrel cell and the Polar cell. The movement of air masses is influenced by coriolis force. It means that the air diverts to the west.
