Evaluation of Daily Precipitation in 1998 Summer over the Tibetan Plateau Using REMO

摘要

Daily variation of precipitation in summer of 1998 over the Tibetan Plateau is studied using a regional climate model called REMO with horizontal resolution of 1/6° driven by European Centre for Medium-Range Weather Forecast (ECMWF) reanalysis data ERA40. In comparison with in situ observational data from the TIPEX-GAME/Tibet, it is found that REMO captures major precipitation cases and reproduces the monsoon onset date. The simulation also shows clear spatial characteristic of daily precipitation pattern over Tibet, which is dry in the west and wet in the east, except unrealistically large rainfall at the southern side of the Himalayas. Therefore, REMO can be used to investigate the water cycle and energy budget over this region in future studies.
