Just to contribute something to the ongoing discussion about humid air....
If I recall my physics properly, warm air will hold more moisture than cold
air, warm air will rise, cold air will settle.
Therefore, as warm air, laiden with moisture, cools and settles, it will
loose the moisture as condensation or fog. If a layer of warm air is
sitting on top of a layer of cool air, moisture will condense out at the
interface. If warmer air contacts a cooler object, such as concrete, it
will loose moisture as condensation.
I believe that is all true. The question then becomes; So what? I have
also heard the story about batteries on a concrete floor losing their
charge. I don't store batteries on concrete and they don't lose there
charge. Unfortunately that doesn't proove anything. I suppose a case can
be made for a current path through condensation on a battery because it is
low, and cool (from heat transfer to the concrete) but it isn't a very
satisfying explanation. What happens in desert climates? Seems like the
only way to answer this is with some good old fashioned scientific research,
or maybe a call to Gates or somebody. Maybe I'll try and work that in to my
schedule.
