What are the vertical distribution of water vapour in the atmosphere and the horizontal distribution near earth surface?
It is assumed that "distribution" means the same as "transfer" and not the relative amounts of moisture in the atmosphere/air at different levels (i.e. near ground and high altitude).
Once moisture enters the atmosphere/air it can be moved about by the winds.
This can be short and long ...
Vertical and horizontal distributions of water vapour are calculated.
