The "Chill Factor" refers to the perceived decrease in temperature felt by the human body due to wind or other environmental conditions. It is often calculated using a formula that combines air temperature and wind speed, resulting in a lower effective temperature. This concept is important for understanding how cold weather can impact comfort and safety. In meteorology, the Chill Factor is also known as the wind chill index. It helps people prepare for cold weather by indicating how quickly frostbite can occur on exposed skin. Knowing the Chill Factor can guide individuals in dressing appropriately and taking precautions during harsh winter conditions.
