What does wind chill represent?

Wind chill represents the feeling of cold that a person experiences due to the combination of low temperature and wind speed. When wind is present, it enhances the cooling effect on exposed skin, making it feel colder than it actually is as measured by a thermometer. This is especially important in understanding how our bodies perceive temperature in various weather conditions.

When wind blows across a surface, it removes the thin layer of warm air that surrounds the body, which can lead to a more rapid drop in skin temperature. The wind chill factor is crucial for understanding the risks of frostbite and hypothermia in cold environments, as it provides a more accurate picture of how cold conditions can affect the human body.
