It considers how much heat a person loses from their bare face. However, with a wind chill effect, the possibility of frostbite is greatly increased. JAG/TI calculates wind chill by looking at a clothed person walking at a speed of 3mph. Great care should be taken to avoid conditions conducive to low temperatures, with or without wind chill factors. That wind effect tends to evaporate the moisture from the air and cause the enhanced cooling effect to humans, plants and animals, just as a breeze does on a hot summer day. While the change in the wind chill factor above 50 MPH is not really negligible, it is minimal. The greatest range of wind speeds for effect is from 5 to 50 MPH. You can also use our wind chill calculator if you wish to see a wind speed or temperature not shown here. Keep in mind that wind speeds of under 5 MPH have a negligible effect on the wind chill calculation. High winds of 96mph on Mt Washington have produced a wind chill factor of -108F (-78C) - comfortably below the lowest point on the National Weather Services (NWS) wind chill chart, which stands. It only describe how a human being would feel in the wind at the ambient temperature. In other words, your 98-degree body loses heat as though it is 8 degrees outside. For example, if a thermometer reads 35 degrees Fahrenheit outside and the wind is blowing at 25 miles per hour (mph), the windchill factor causes it to feel like it is 8 degrees F. Wind chill does not affect objects and does not lower the actual temperature. The windchill factor is the temperature that a person feels because of the wind. This table has factors of wind speed in miles per hour (MPH) in the vertical columns, getting progressively faster from top to bottom of the chart, and temperature in degrees Fahrenheit in the rows, getting progressively colder from left to right. This means that, with a wind of 20 km/h and a temperature of -25☌, one would feel as if it were -37☌ in a very light wind. That effect is called the wind chill factor. Often cold temperatures can feel much colder based on the speed of the wind.
