   Is there some convenient approximate formula for determining what proportion of available moisture precipitates at different altitudes with downwind rising terrain? A rather crude approximation suffices but I’ve never seen one.

   The PRISM group at Oregon State U. developed a model to do that, although you may not find it very convenient. I don’t believe the project suffered much from the involvement of George Taylor.
