Wind – air that moves horizontally. convection cell – a pattern of rising and falling air, sinking air, and winds caused by unequal heating and cooling.

Wind & Climate Wind – the horizontal movement of air. Low pressure – warm air rising. High pressure – cold air falling. Winds always blow from high pressure.
