The wind chill temperature is how cold people (and animals) feel while outside. Wind chill is based on the rate of heat loss from exposed skin caused by the combination of wind and cold, according ...
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 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 ...
The heat index and humidex measure the effect of humidity on the perception of temperatures above +27 °C (81 °F). In humid conditions, the air feels much hotter, because less perspiration evaporates from the skin. The wind chill factor measures the effect of wind speed on cooling of the human body below 10 °C (50 °F). As airflow increases ...
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 ...
In gliding, wind gradients just above the surface affect the takeoff and landing phases of flight of a glider. Wind gradient can have a noticeable effect on ground launches, also known as winch launches or wire launches. If the wind gradient is significant or sudden, or both, and the pilot maintains the same pitch attitude, the indicated ...
The National Weather Service office in Jacksonville said it was expecting temperatures to dip below freezing early Thursday morning, with wind chill values reaching into the lower 20s that had ...
