The primary cause of airflow is the existence of air. ... Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.

What is the pattern of air flow?

Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. ... This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It's also affected by the spin of the Earth. In the tropics, near the equator, warm air rises.

How does air flow in a room?

Cold air flows downward according to hot air because it is more dense and sinks while hot air rises. In hot room the air will be much thinner thus reducing the pressure so the air flows from cold room to hot rooms. Cold air sucks out the energy of hot air! ... Cold air will always come in through other cracks!
