The Wind Chill Temperature is a single value that takes both air temperature, and wind speed into account. Both the heat and wind chill indexes are an apparent or perceived temperature. A temperature profile, which is linear at steady state, is shown for windy and calm conditions. To calculate wind chill use the equation: Wind Chill = 13.12 + (.6215 x T) - (11.37 x V 0.16) + (.3965 x T x V 0.16) Example: When the temperature (in Celsius) is 2 degrees, wind speed is 7 km/h, the effective wind chill is: Wind chill minus 10 this evening and minus 16 overnight. Wind chill is based on how much heat is lost from exposed skin while it's windy and cold. Wind chill near minus 10. Wind up to 15 km/h. Wind Chill Index - Wind Speed in mph and Temperature in degrees Fahrenheit. Winter Weather Forecasts … The wind chill temperature is a measure of how cold it really feels outside based on the air temperature and wind speed. Wind-chill definition: the serious chilling effect of wind and low temperature: it is measured on a scale that... | Meaning, pronunciation, translations and examples This heat loss can be calculated for various combinations of wind speed and air temperature and then converted to a wind chill equivalent temperature (or wind chill … Windchill is based on the rate of heat loss from exposed skin caused by wind and cold. You may also hear forecasters refer to wind chill as the "feels-like" temperature. Exposed skin at very cold wind chills can freeze in only minutes. The wind chill temperature is never higher than the air temperature, and the windchill is undefined at higher temperatures (above 10 °C). Enter a temperature, in either Fahrenheit or Celsius. The chilling effect of the wind can be represented by the lower temperature that would be required to produce the same chilling sensation for a person walking in calm conditions. Wind chill is the measure of the perceived apparent temperature, whereas temperature itself is the measure of the kinetic energy of the moving particles of matter. Be prepared for the day. Then enter a Wind Speed, in either Knots or Mph. Sunshine could increase the wind chill temperature a little in a range from 10° F to 19° F. How to use this calculator. Therefore, we cannot measure the thermal sensation with a thermometer. Wind Chill temperature is defined only for temperatures at or below 10 °C (50 °F) and wind speeds above 4.8 kilometres per hour (3.0 mph). Árni Sigurðsson 26.2.2010. You can read about wind chill in wikipedia but, in short, wind chill, or wind chill index, or wind chill factor, is the felt air temperature on exposed skin due to wind. Mainly cloudy. It measures how cold it feels outdoors when wind speed is factored in with the actual air temperature. Check the current conditions for Cleveland, OH for the day ahead, with radar, hourly, and up to the minute forecasts. To calculate the wind chill, you need: The temperature: use a thermometer or your current conditions. It may also be referred to as the "feels-like" temperature. If it were 35 degrees outside with a wind chill of 25, you might think you’re in danger of getting frostbite . Wind chill is the temperature sensed by humans as a result of air blowing over exposed skin. The wind chill index. The calculations are based on the formula posted on the National Weather Service's website, as of 2009. The wind chill temperature translates your body’s heat losses under the current temperature and wind conditions into the air temperature with a 3-knot wind that would produce equivalent heat losses. Tonight: Partly cloudy. Temperature °F °C Wind Speed Mph Knots Wind Chill °F °C: Wind Chill Chart and Explanation. Canada’s wind chill index combines the temperature with the wind speed to express this cooling effect in temperature-like units. Wind Chill is the lowering of body temperature due to the passing-flow of lower-temperature air. In Chicago, for example, wind gusts of up to 24 miles per hours will generate a temperature with wind chill of minus 50 or 60 degrees Fahrenheit. Write a program that prompts the user to enter a temperature between -58ô°€F and 41ô°€F and a wind speed greater than or equal to 2 and displays the wind-chill temperature… The wind chill calculation is based on wind speed and outdoor temperature, as shown in the table below. This is not an easy conversion. The opposite of the heat index is the wind chill temperature. But what exactly is wind chill… Wind chill just tells you the rate at which your skin will reach the air temperature. The formula cannot be used for wind speeds below 2 mph or temperatures below -58ô°€F or above 41ô°€F. A biting wind can make cold temperatures feel even colder. Select the wind speed unit between mph, km/h, m/s, ft/s, knots; Enter the wind speed; Choose the temperature unit between degrees Fahrenheit, degrees Celsius, or … High minus 7.
