The wind chill index only accounts for a human body's sensible heat loss, which is the heat loss caused by the transfer of heat from a person's skin to the surrounding air. It does not account for the potential warming effect of sunlight on the body, which is why it is not accurate in all weather conditions. However, it is still a useful index for forecasting the effects of cold and wind on the human body.
