Things not talked about
There is a weight difference between H2O and C2O That is carbon di oxide and water If you increase the weight of the atmosphere the damage done by this heavier atmosphere must be greater in cyclonic conditions.
.The next thing to look at is the friction values of these two substances and I do not know which has more friction. But lets assume for a moment that carbon di oxide has a greater friction the the damage done by the lets say stickier atmosphere also does more damage than a loose atmosphere.
Just my thoughts.
