Interesting. There's a counter-intuitive effect: When an evaporative house cooler is ducted to skim the boundary layer from a hot roof, the output air is cooler than for the normal inlet configurations. I was hypothesizing that since water gas is lighter than N², it would diffuse away from the roof faster and dry out the air, but I haven't found any information about that effect.

Background: Thermophoresis http://en.wikipedia.org/wiki/Thermophoresis [quote]Thermophoresis, thermodiffusion, or Soret effect (or Ludwig-Soret effect), is a phenomenon observed when a mixture of two or more types of motile particles (particles able to move) are subjected to the force of a temperature gradient and the different types of particles respond to it differently. The term "Sorét effect" normally means thermophoresis in liquids only. The term "thermophoresis" is most often intended to mean the behavior in aerosols, not liquids, but the broader meaning is also common. The mechanisms of thermophoresis in liquid mixtures [Hoyt A. Stearns Jr.] ...
