Answer:
Colder temperatures cause the air to be more tightly packed which increases the air pressure.
Step-by-step explanation:
The air pressure represents the weight of the air. It is directly dependent on the temperature. The colder the temperature, the heavier and denser the air, the higher the temperature, the lighter and less dense the air. This is simply because of the manner in which the molecules react at different temperatures.
When the temperatures are lower, the molecules of the air are getting closer to each other, thus the air becomes denser, so in a given area it is heavier and the air pressure is higher. When the temperatures are higher, the molecules spread out, thus they are further away from each other, which in turn makes the air less dense, lighter, so in a given area the air pressure is lower.
