What is the wind chill?
Wind chill, also spelled windchill, also called wind chill factor, a measure of the rate of heat loss from skin that is exposed to the air. It is based on the fact that, as wind speeds increase, the heat loss also increases, making the air “feel” colder.
What does wind chill effect?
The windchill factor is the temperature that a person feels because of the wind. The windchill factor is the same effect that causes you to blow on hot soup to cool it down. The movement of the air increases the soup’s loss of heat by convection, so the soup cools down faster.
What is wind chill and why is it important?
According to the National Weather Serivce, the wind chill number is an approximation of how cold the air feels to your body, based on the rate of heat loss from exposed skin caused by wind and cold air. Our bodies naturally lose heat through convection, even when wind isn’t present.
How is wind chill determined?
A good approximation of the wind-chill temperature can be found by multiplying the wind speed by 0.7 and then subtracting that value from the air temperature. The wind-chill temperature assumes a human face at a height of 5 feet above the ground on a clear night. Wind speed magnifies the effect of cold temperatures.
Is wind bad for health?
The experiment concluded that, even after adjusting for other weather variables, wind direction had a notable effect on mental health; specifically, a southeasterly wind raised anxiety and lowered energy levels. In other words, it blew no good.
How does wind affect human behavior?
Dr Mitchell says that the study found that increased wind power was associated with a higher “negative affect” – meaning people were more likely to feel irritable, jittery, or distressed.
What is wind chill and how does it affect the human body?
Wind chill is the temperature it “feels like” outside and is based on the rate of heat loss from exposed skin caused by the effects of wind and cold. As the wind increases, the body is cooled at a faster rate causing the skin temperature to drop.
