What is a strong wind?
Short bursts of high speed wind are termed gusts. Strong winds of intermediate duration (around one minute) are termed squalls. Long-duration winds have various names associated with their average strength, such as breeze, gale, storm, and hurricane.

Is 15 mph winds cold?
For wind speeds between 5 mph and 45 mph, the following formula may be used to calculate the wind chill factor — where t is the temperature in degrees and v is the wind velocity in miles per hour….

| 0° F to -15° F | Very cold. Very unpleasant. |
Are 20 mph winds cold?
This means that despite it being 0 degrees F on a very cold morning, when factoring in the wind (for example 20 mph), it can feel like a much colder temperature (in this example, -22 degrees F).
How much wind can a human withstand?
Humans can survive blasts of 500 mph wind, which is important because pilots sometimes need to eject from airplanes at those speeds. In the 1940s, the US government put pilots in wind tunnels to learn how they reacted to high winds.

Can the wind cut you?
Because you cannot cut with a wind at a distance. Up close, a compressed air can easily cut human flesh. But at a distance, the compressed air expands rapidly and can no long be a cutting tool (nothing is sharp any more at a distance). Previous answers mention this in some form.
