Question

which two considerations are used to calculate a windchill factor?
wind speed and air temperature
air pressure and wind direction
wind direction and atmospheric heating
atmospheric heating and air temperature

Explanation:

Windchill factor is calculated based on how wind affects the rate of heat loss from the human body. Wind speed increases the rate of heat loss (by convection), and air temperature is the baseline temperature against which the cooling effect is measured. Air pressure, wind direction, and atmospheric heating are not directly used in the standard windchill calculation formula.

Answer:

wind speed and air temperature
