How does cooler air move in relation to warmer air?

cold air moves down

Explanation:

Winds are blowing from a region of cold air to a region of warmer air, which results in cooling of the warmer region. As the cold advection persists, temperatures in the warmer region will begin to decrease as the colder air moves into the region of warmer air.
