Not directly I'd agree, but it is often that case that in air that is 
cold enough, moisture content is at a minimum. Certainly, my coil 
here at work is up to its best on a frosty morning. Coincidentally, 
an E.S. meter I placed in a carpeted room shows the highest generated 
voltages by someone walking over the carpet in suitable footwear in 
such conditions.

Malcolm
