Jed, with regards to your earlier post... I think the increase in steam may largely be due to the change in weather. A west wind would indicate cool moist air being blown towards the hill, and the heated rock of the dome would likely create steam...

Maybe. I think you have a point with the west winds and more moisture in the air. I think it also has to do with that moisture saturating the air (and the explanation above). The normal steam comes from water flowing in fissures.
Barometric pressure, Humidity...we can sort all this out!
