Wind Chill Effect Explained

The wind chill is not a true measure of cold. Moving air causes the body to lose more heat than still air. Thus, wind speed becomes a factor in how you will get affected.

For instance, if the air in your environment is 0 (zero) degrees Celsius and the wind speed is 10 km/h at that moment, then the air temperature felt is minus 3 degrees Celsius. Even if the air temperature does not change, the increase in wind speed causes the temperature you feel to decrease.

Wind Chill Table

Layers such as clothes, tents and sleeping bags are barriers that protect us from getting wet, cold and wind chill. Staying dry on the mountain at high altitude is the key to survival. Water transfers heat 20 times more than air. On a mountain with 40 km/h wind blowing at minus 15 degrees Celsius, you will feel minus 27 degrees Celsius, and if your clothes are wet, you will lose heat 20 times faster.

In addition to facing the risk of hypothermia, local frostbite may occur in your body, such as ears, nose and fingers. The limbs that can be most affected by the cold and the wind chill effect are the fingers. When sweaty hands in thick gloves come out of the gloves for tasks such as tying ties and operating electronic devices, they will be affected by both the cold, the wind chill effect and the 20 times more heat transfer that will occur on the fingers wet due to sweating. To avoid such a situation, wearing a liner can be a preventative solution.
