%X This paper first analyzes the differences of the wind and relative humidity fields of FGGE level-IIIb data set for the period from June to July 1979 over the Tibetan Plateau from the truth and reveals the necessity to revise the data set over the west of the Plateau.Then,the initial wind and relative humidity fields in a regional model is corrected,parts of its physical processes modified,and its horizontal resolution inereased.Six predicting experiments are designed.A set of 24-h forecasts of two Plateau vortex/shear line precipitation cases are carried out.The results show that:the precipitation forecast over the Plateau can be clearly improved by modifying thd initial field and model Physics.The now field can also be improved to some extent.This shows that the above modification schemes are feasible.However,the nesting scheme of the model over the Plateau remains to be modified.The next efforts should focus on improving the forecast skill for the Plateau vortex now field.
