Wind can affect the temperature of a place in several ways. When the wind blows, it carries away heat from the surface, causing the temperature to drop. This effect is known as wind chill, and it can make the air feel colder than the actual temperature. Conversely, when there is no wind, the air around us can feel warmer because the heat is trapped close to the surface. Additionally, winds can bring in colder air from other regions, resulting in a decrease in temperature. On the other hand, warm winds can bring in warm air, causing the temperature to rise. Overall, the effects of wind on temperature depend on the speed and direction of the wind, as well as the characteristics of the surrounding landscape.
At night, the earth's surface cools by radiating heat off to space. The strongest cooling takes place right near the surface while temperatures at roughly 3000 feet are actually warmer than those at the surface. On a windy night, some of the warmer air aloft is mixed down towards the surface. This occurs because the winds are faster aloft than at the surface.
To visualize this, place one hand over the other about six inches apart. The bottom hand represents the air near the surface and the top hand represents the warmer wind higher up. Move the bottom hand slowly and the upper hand faster (to indicate the faster winds aloft). The faster air above and slower air below causes the air to overturn or spin (as in the picture below). This overturning motion is how warmer air from above is transported downward on windy nights.
