How do you find out the wind chill?

Answer 1

In order to calculate the wind chill information about the temperature and the wind speed is required.

The formula is wind chill index Twc = 13.12 + 0.6215Ta - 11.37V0.16 + 0.3965TaV0.16. Where Ta is the temperature in celsius and V is the wind speed in km/h. Twc differs from Ta only if V is greater than 4.8.

Answer 2

Having been in Anchorage AK ('65-'67 and felt it 50 below zero with a 25 knot wind it was the same as 75 below with no knot wind,capish?)I remember that (for example). if the temp. is 18 (above zero) degrees Fahrenheit with an 18 knot wind then the chill factor degrees is zero degrees Fahrenheit. I.E. 1 degree minus for each knot of wind,capish?

Answer:

Wind chill is a measure of the cooling effect of wind not the temperature of the air. It is not measured value but a calculated value. Wind increases the rate at which a body loses heat by keeping the air close to the warm object cooler. In quiet conditions warm air tends to stick closer to the warm object and insulates it. So the air on a windy day feels cooler than the temperature indicated by a thermometer by increasing the rate of heat loss to that of air at the windchill temperature.

The equation for this heat loss can be calculated with various combinations of wind speed and air temperature and then converted to a wind chill equivalent temperature (or wind chill factor).The equation is:

Wind Chill (Fo)= 35.74 + 0.6215T - 35.75(V0.16) + 0.4275T(V0.16)

Where:

T = Measured Air Temperature (Fo)

V = Wind Speed (mph)

Answer 3

The fun way is calculate it from data:

Wind chill is a measure of the cooling effect of wind. Wind increases the rate at which a body loses heat by keeping the air close to the warm object cooler.

Where:

V = Wind Speed (mph)

Answer 4

Windchill (°F) = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16

T = temperature
V = wind speed

Answer 5

Windchill (°F) = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16

T = temperature
V = wind speed

Answer 6

32 degrees F.
