Just an aside on wind-chill as mentioned in the OP - 3wind chill is only relevant to an object which is trying to maintain its temperature ABOVE the ambient air temperature. Wind chill is a measure of the extra energy required to sustain a given temperature when there is a cooler wind.
If you have an object which is trying to maintain its temperature at 10degC in an air temperature of 10degC the wind will make no difference to the required energy.
If you have an object which is trying to maintain a temperature of 20degC in an ambient air temperature of 10degC then the amount of energy required will vary with the wind speed.
If you have an object which is NOT trying to maintain its temperature, but is in an ambient air tempeerature of 10degC, then no amount of wind will cause it to get colder than 10degC.
Humans feel wind-chill because our bodies try to sustain a constant temperature, but airframes don't...
