Wind chill is calculated by combining wind speed with air temperature to represent how cold it actually feels to exposed skin. The concept is based on how moving air accelerates the heat loss from the body, which can make the ambient temperature feel significantly colder. The faster the wind blows, the more heat is removed from the body, leading to a lower perceived temperature.

It's important to note that this calculation does not involve measuring humidity, which primarily affects comfort levels but is not a factor in wind chill. The time of day and observing weather patterns also do not play a direct role in the wind chill calculation, as they are more related to general weather conditions rather than the specific mathematical relationship between temperature and wind speed.
