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.
Wind Chill is a 2007 supernatural horror film directed by Gregory Jacobs and starring Emily Blunt and Ashton Holmes. The film was produced by the British Blueprint Pictures company, and George Clooney and Steven Soderbergh's joint company Section Eight Productions supported the project financially. The film opened in limited distribution in ...
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
Charles Eagan (1921 – March 11, 2010) was a Canadian scientist working in cold weather physiology, known primarily for advancing the wind chill formula.. Antarctic explorers Paul Siple and Charles Passel had created their original formula for wind chill measurements in 1939 by drawing on data that showed how long it took water to freeze in a cylinder under various wind and temperature ...
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 ...
Charles Fay Passel (April 9, 1915 – December 27, 2002) was a polar scientist responsible along with Paul Siple for the development of the wind chill factor parameter. Biography [ edit ]
In April 2014, ECCC replaced the "wind chill warning" with an "extreme cold warning." In the older system a wind chill warning for Southern Ontario and Atlantic Canada was issued when the wind chill dropped to -35. Thus a temperature of −37 °C (−35 °F) with no winds would not require a warning be issued.
You can also approximate the wind chill with a little mental math: If the temperature is minus 13 degrees and the wind speed is 15 mph, the wind chill will be somewhere between minus 32 and minus 39.
