What causes wind chill?

Answer 1

The wind-chill factor is a method for accounting for the effect of wind speed which affects the rate of heat loss of the human body. In cold, still air, we continually lose body heat at a rate depending on the temperature difference between the skin and the air, and the amount of insulation - like clothing - we're wearing. When the skin loses heat, it will cool to somewhere below 37 C. The colder the air, the greater the heat loss and the skin cooling. When the wind picks up speed it will carry away the warmish air layers immediately next to our skin and in our insulating clothing. The skin temperature is further decreased and we interpret that as our being in a colder environment. The greater the wind speed, the greater loss of that warmed air layer next to our body. There are two different ways, one used by the Australians and Europeans, another used by The USA and Canada. You can follow the links for more details. Both provide the actual formula for calculating the wind chill factor. The NOAA link has interactive charts.

Answer 2

Wind chill is caused by the combined effect of wind and temperature on the human body. When wind blows, it removes heat from our skin at a faster rate, making us feel colder than the actual air temperature. The stronger the wind and the lower the temperature, the greater the wind chill effect.

Answer 3

Wind chill is the apparent temperature felt on exposed skin due to wind. The degree of this phenomenon depends on both air temperature and wind speed. The wind chill temperature (often popularly called the wind chill factor) is always lower than the air temperature for values where the wind chill formula is valid. In cases where the apparent temperature is higher than the air temperature, the heat index is used instead. (Wikipedia)

Wind chill is the lowering of temperature caused by the wind.

Answer 4

Cold temps are intensified (both perceived and actual) by air moving over your skin or other surfaces...

Answer 6

The wind chill index measure Wind chill factor

Answer 7

The calculation using the actual temperature and the wind speed to obtain the equivalent chill temperature from th wind chill chart.

Answer 8

A wind chill warning is when the wind chill is expected to be below -40 degrees Fahrenheit for at least 3 hours. Wow i answered a question on wikianswers! rock on!

Answer 9

No. Wind is caused from air fronts of different temperatures colliding. Chill factor is what the temperature feels like.

Answer 10

When the wind is blowing it increases the rate of evaporation of moisture from our skin. The evaporation absorbs heat, making it feel colder.
