All other things being equal except air temperature, would a cold wind exert more force than a warm wind?
Yes, cold air is denser than warm air, meaning that there are more air molecules in a given volume of air. Therefore, a cold wind would exert more force than warmer air. This difference in density comes into play in transportation and sports as well. For example, the airfoil of airplane wings generates more lift in cooler air than warmer air, decreasing the distance and speed required for takeoff. Batted baseballs travel farther in warmer conditions, as there are fewer air molecules offering resistance to the flight of the ball. On the other hand, pitchers prefer cooler temperatures, as curve balls have more “bite” when they encounter more air molecules. There’s plenty more about air density on this USA TODAY resource page.
