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 ...
The U.S. and Canadian weather services revised the wind chill index in 2001, based on greater scientific knowledge and on experiments that tested how fast the faces of volunteers cooled in a wind ...
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.
A cold weather advisory (formerly known as a wind chill advisory until October 2024) [1] is a hazardous weather statement issued by Weather Forecast Offices (WFO) of the National Weather Service (NWS) in the United States to alert the public that temperatures or wind chills are forecast to reach values low enough that it poses a threat to human health and life if adequate protection is not ...
The NWS office in Tulsa, Oklahoma, in conjunction with Oral Roberts University's mathematics department, published an approximation formula to the WBGT that takes into account cloud cover and wind speed; in limited experimentation (four samples), the office claimed the estimate was regularly accurate to within 0.5 °F (0.28 °C), even with a ...
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. The hot-weather version of the AT (1984) is used by the National Weather Service in the United States. In the United States, this simple version of the AT is known as the heat index.
Wind damage and a few tornadoes are possible. -A second round of severe weather could materialize Saturday and Saturday night from eastern Texas to western Georgia and southern and middle Tennessee.
Articles on forecasting and analysis techniques, forecast verification studies, and case studies useful to forecasters. In addition, submissions that report on changes to the suite of operational numerical models and statistical post-processing techniques, and articles that demonstrate the transfer of research results to the forecasting community.
