8.1.4.25 Geometric and physical applications

condition: The felt temperature, or wind chill index, is the temperature that we would have to have in the absence of wind in order to feel as cold as under real wind and temperature conditions. Weather forecasting services in a number of countries use the following model to calculate the wind-chill index \( W \) : \( W=13.12+0.6214 \cdot T-11.37 \cdot V^{0.16}+0.3965 \cdot T \cdot V^{0.16} \), where \( T \) - temperature in C
