If dominant precip type is requested (i.e., Zhao-Carr MP scheme), 4 more algorithms in calpreciptype() will be called. the tallies are then summed in calwxt_dominant(). For GFDL cloud MP scheme, determine convective rain/snow by surface temperature; and determine explicit rain/snow by rain/snow coming out directly from MP. More...
