[RegCNET] lake model

[Richard Anyah]

Hi Mike,

The following publications may be relevant, though they use lake model 
from variants of the RegCM family for Lake Victroia in equatorial 
eastern Africa.

        You may have to compute changes in E, P and horizonatal mosture 
convergence to infer lake level fluctuations.
       Also the 1D lake use simplified vertical exhange of moisture and 
heat between the lake and the atmosphere.(See refs. 1, 2 and 4 above)

As far as I know  when the lake is tuurned off, the "lake" surface 
temperature uses the  surface temperature, unless you physically 
prescribe 'climatological' temperature over the lake surface



Hope the information may be helpful.
