[QUOTE="hutchphd, post: 6854547, member: 635497"] Yes but not directly. Humid air is difficult to cool because of this water content. Also it is actually less dense than "dry" air at a given temperature. So an advancing cold front will cause the warmer humid air to rise and this will continue as the moisture content is "wrung out" allowing very significant and violent updrafts before these columns of air become cold clouds. It is this motion (and perhaps the water droplets) that generates the charge separation. But the energy comes mostly from the condensation. [/QUOTE]
