Surface Dew Point Temperature

The following four panels show the 2000 UTC (1500 LST) 1.5 m dew point temperature (C) for increasing values of lake surface temperature. Note that when no lake breezes are occurring (+20K case), air in regions downwind of the lakes is significantly less moist.

          Lake surface temperature climate values 
            Climates values + 10K 
            Climate values + 13K
            Climate values + 20K
