  This study examines the sensitivity of simulated precipitation to planetary boundary layer (PBL) schemes over the Tibetan Plateau (TP) and the Yangtze River Valley (YRV). The summer precipitation from 15 June to 30 July 2010 is simulated with the Weather Research and Forecasting (WRF) model over these areas. Three PBL parameterization schemes, Mellor-Yamada-Janjić (MYJ), Yonsei University (YSU), and Medium-Range Forecast (MRF) are compared in the simulation. The simulated hourly precipitation overestimates the observed precipitation, and the simulation of MRF scheme is more close to the observation. In general, the WRF model shows good (poor) ability in simulating the diurnal cycle of precipitation over the TP (the upper YRV). Although the WRF model simulates a two-peak pattern different from the observed one-peak pattern in the middle YRV, both of them are general.. View More»
