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.
For example, in a scenario where the actual temperature is 10 degrees but the "feels like" temperature is -5 degrees, what that really means is that the wind chill is making it feel as if the air ...
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.
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 ...
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.

Temperature anomaly is the difference, positive or negative, of a temperature from a base or reference value, normally chosen as an average of temperatures over a certain reference or base period. In atmospheric sciences , the average temperature is commonly calculated over a period of at least 30 years over a homogeneous geographic region, or ...
The wind chill factor makes the weather feel colder under windy conditions than calm conditions even though a glass thermometer shows the same temperature. Airflow increases the rate of heat transfer from or to the body, resulting in a larger change in body temperature for the same ambient temperature.
