(To remind yourself why the warmer and less dense air will rise, see the earlier chapter on buoyant forces). Notice that the spinning of the Earth combined with the inertia of the air mass creates a Coriolis Effect, which causes the wind direction to curve away from the direction indicated at the bottom of the convection cell.
