F - Curvature term is added to the horizontal momentum equations for the nonhydrostatic model.
Effect is small.
Memory increase is minimal. F - The condition to print out whether 4DDA is used in a run is changed so that it prints only if 4DDA is used in the run, not just compiled. F - A change is made to avoid using uninitialized array when 4DDA option is not compiled in hydrostatic code. F - A warning print is added in Grell scheme if downdraft is initiated at the top of the model.
