The perceived decrease in air temperature felt by the body on exposed skin due to the flow of air is determined by two primary meteorological measurements. These measurements allow for a calculation that quantifies the cooling effect of wind. For example, a thermometer may read -5C, but the concurrent effect of a moderate breeze could result in a perceived temperature significantly lower.
Understanding this phenomenon is crucial for assessing risks associated with cold weather exposure. It informs decisions related to appropriate clothing, outdoor activity limitations, and public health advisories. Historically, various formulas have been developed to estimate this effect, with ongoing refinements to improve accuracy and reflect diverse environmental conditions and physiological responses.
