In this study, the effect of a scale-aware convective parameterization scheme (CPS) on simulation heavy precipitation in gray-zone was investigated using Weather Research and Forecasting (WRF) model. We performed WRF simulations with Kain–Fritsch (KF) (non-scale-aware), Multiscale (MSKF) (scale-aware), explicit convection (i.e., no CPS). The MSKF uses parameter that modulates available potentia...
