Wind chill index values for a range of temperatures and wind speeds, from the standard wind chill formula for Environment Canada. Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere.
The simple interpretation of the wind chill is how cold the air feels when the wind is factored in. This is the winter counterpart to the "heat index" when it comes to "feels-like" temperatures.
Wind chill makes it feel much colder than it really is, so it's been described as a "feels-like" number. If the temperature is 0 degrees and the wind is blowing at 15 mph, the wind chill is 19 ...
Here is a chart by the National Weather Service that shows the wind chill for various air temperatures and wind speeds. Wind chill history in Greater Cincinnati. In recent weeks, wind chill values ...
A wind chill warning was a hazardous weather statement previously issued by both local forecast offices of the National Weather Service (NWS) in the United States and by the Meteorological Service of Environment and Climate Change Canada (ECCC) when wind chills were forecast to reach values low enough for residents and travelers to be susceptible to life-threatening medical conditions (such as ...
Air temperature and wind chill are no colder than −73 °C (−99 °F) And also must meet one or more of the following criteria: Visibility less than 300 metres (980 ft) Windspeed is greater than or equal to 48 knots (89 km/h; 55 mph) Air temperature and/or wind chill of −60 °C (−76 °F) or below; Weather Condition 1
The Australian formula includes the important factor of humidity and is somewhat more involved than the simpler North American wind chill model. The North American formula was designed to be applied at low temperatures (as low as −46 °C or −50 °F) when humidity levels are also low.
With high wind speeds forecasted in the state, it'll feel much colder than the actual temperature. Here's what to know about wind chill and what the term means.
