Abstract

By using high resolution 3″DEM data, precipitation data from May to October of 94 weather stations in the east of Qinghai-Tibet Plateau, based on multivariable stepwise regression method, the estimating model of monthly precipitation are done combined with terrain factors. The result shows that the estimated results of precipitation are very well, relative errors are less than 20%, the correlative coefficient pass the test of 0.95. Under the influence of summer monsoon, the precipitation distribution is different in the north and the south region, and the high value center of precipitation is developed south, moved east and withdraw south, which reflects the transferring law of water-vapor of monsoon. The influence of terrains factors on precipitation is marketable.
