Relationship between air pressure and season

Relationship between atmospheric pressure and seasons: the atmospheric pressure in winter is higher than that in summer. The change of temperature is a very important reason for the change of atmospheric pressure. When the air is cooled, the air contracts, the density increases, the weight of air column per unit area increases, and the air pressure also increases. Therefore, the arrival of cold air is always accompanied by the increase of air pressure; When warm air comes, the air pressure tends to drop. Winter is a world of cold air and summer is a world of warm air, so obviously, the air pressure is high in winter and low in summer. It should be noted that because the density of air decreases with the increase of altitude, generally speaking, the pressure is compared at the same altitude, and the most commonly used is the sea level pressure.
