Abstract. Several sensitivity experiments with the Weather Research and Forecasting (WRF) model version 3.8.1 have been performed to find optimal parameterization setup for precipitation amounts patterns around Mount Kenya at a convection-permitting scale of 1 km. Hereby, focus is on cumulus scheme, tests Kain–Fritsch, Grell–Freitas, no parameterizations. In addition, two longwave radiation sch...

Abstract Dynamical downscaling generally performs poorly on the Tibetan Plateau (TP), due to region’s complex topography and several aspects of model physics, especially convection land surface processes. This study investigated effects cumulus parameterization scheme (CPS) land-surface hydrology (LSHS) TP climate simulation during wet season using RegCM4 regional model. To address these issues...

Weather simulations are sensitive to subgrid processes that parameterized in numerical weather prediction (NWP) models. In this study, we investigated the response of tropical cyclone Idai different cumulus parameterization schemes using Research and Forecasting (WRF) model with a 6 km grid length. Seventy-two-hour (00 UTC 13 March 00 16 March) were conducted New Tiedtke (Tiedtke), Simplified A...

Abstract. The performance of the Weather Research and Forecasting (WRF) model version 3.8.1 at convection-permitting scale is evaluated by means several sensitivity simulations over southern Peru down to a grid resolution 1 km, whereby main focus on domain with 5 km horizontal resolution. Different configurations microphysics, cumulus, longwave radiation, planetary boundary layer schemes are te...
