This NASA image shows large-scale atmospheric circulation on Earth. Notice the three dimensions of the circulation. On the right-hand side of the image the arrows show vertical and horizontal air flow as part of six convection cells, three in each of the Northern and Southern hemispheres. There are also three air circulation cells in the Northern Hemisphere and three in the Southern Hemisphere. These cells help distribute heat and air across the Earth because each cell is like a wide, windy belt around the globe. What drives air circulation around the globe?
