The Global Air Circulation

On the sphere-shaped ^{gömb alakú} Earth warming up differs at the different places. It is the strongest along the Equator, and the weakest at the poles, and due to this the air pressure is low at the Equator and high at the poles. Low pressure zones form in the district of the latitude 60 and high pressure zones around the latitude 30. Due to the cyclones and anticyclones forming in the jet streams, the moving of the air is ascending (low-pressured zones) and descending (high-p.z.).
