Abstract:
A statistic model for the spatial distribution of precipitation estimation in Urumchi is presented. By using the station information compiled by the National Meteorological Center and the precipitation data of 45 years (1955 to 2000) from three stations in Urumchi,the relations between precipitation and regional geographic and topographic factors such as longitude,latitude, and altitude,is studied with stepwise regression. The results show that the estimated precipitation is highly close to the real distribution of precipitation qualitatively and quantitatively.
