Wind chill numbers are always lower than the air temperature for values where the formula is valid. 35.74+.6215*T-35.75*W^.16+.4275*T*W&.16 Where T is temperature; W is wind speed How do news weather persons know that when there is a 10mph wind with a temperature of 5 degrees F that the real temperature we feel is -10 degrees F? This is due to the interaction of air temperature and wind on the human body that is already giving off heat. This effect is known as the wind chill factor, a measure of the cooling effect of wind. To help you calculate the degree of protection you’ll need on a ride, we created this wind chill calculator for motorcycle riders, with wind chill factor expressed at common cruising speeds. There is a specific formula that can be used to calculate wind chill. Calculation of Wind Chill Wind chill or wind chill factor is the apparent temperature felt on exposed skin due to the combination of air temperature and wind speed. Wind chill is popularly known as wind chill factor. Wind chill temperature is only defined for temperatures at or below 50 °F (10 °C) and wind speeds above 3 mph (4.8 km/h, 2.6 kn, or 1.3 m/s). Both temperature and wind cause heat loss from body surfaces. Just input your values and the Wind Chill factor will be automatically calcuated as you type. The index is defined for temperature at or below 10℃ (50F) and wind speed above 4.8km/h (3mph). Any wind that blows below 4.8 km/h or 3 mph doesn’t provide a significant wind chill. We want to see your websites and blogs. For a given combination of temperature and wind speed, the wind chill index corresponds roughly to the temperature that one would feel in a very light wind. The general basis for the wind chill is that the higher the wind speed and the lower the temperature the colder you will feel because the wind is wicking away the heat from the surface of your skin. Enter type temperature and wind speed value : Temperature C F Wind Speed kt ... °F : Wind speeds of less than 5 kt have virtually no wind chill factor on the formula. For example, a temperature of -25°C and a wind speed of 20 km/h give a wind chill index of -37. Wind Chill Formula. Wind chill may be calculated as follows: The above equation cannot be used at wind speeds below about 2 mph or temperatures above 40°F. ! In extreme conditions, this can be a major factor in how soon frostbite sets in. People would then know an approximate time before exposed areas of the body would succumb to frostbite. Wind increases the rate at which a body loses heat, so the air on a windy day feels cooler than the temperature indicated by a thermometer. A common formula for calculating the Wind Chill Index has been developed and widely used in the United States.
