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.
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 ...
The wind chill also isn't a meteorologist's best guess at what the air outside feels like, because it's based on the actual measured temperature and wind speed. There's an equation to calculate ...
On Jan. 30, 2019, the wind chill values in Greater Cincinnati plunged below -30 degrees in some places, making it feel colder than parts of Antarctica at the time.. On that day in Hamilton County ...
Apparent temperature, also known as "feels like", [1] [2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.
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 ...
In the United States an extreme cold warning was an experimental weather warning issued by the National Weather Service in North Dakota, South Dakota, and Minnesota. [5] The warning was issued if the temperature fell to −35 °F (−37 °C) or colder with a wind of less than 5 mph (8 km/h; 2 m/s). [6]
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 ]
