The relationship between temperature and air pressure

Relationship between temperature and air pressure: The higher the temperature, the lower the air pressure.

In an open environment, the higher the temperature, the lower the air pressure; In a closed environment, the higher the temperature, the higher the air pressure. When the ground temperature rises, the density of air will decrease and the thermal movement of air molecules will increase, thus reducing the air pressure.

However, it should be noted that the relationship between air pressure and temperature is also affected by other factors, such as geographical location, season, weather system and so on. So we can't simply think that the increase of temperature will lead to the decrease of atmospheric pressure, or that the increase of atmospheric pressure will definitely warm the temperature.

Atmospheric pressure is related to altitude, atmospheric temperature and atmospheric density, and generally decreases exponentially with altitude.
