A Study on Precipitation Spatial Variability

摘要

Precipitation is resulted from a series of complex process. Spatial distribution of precipitation is affected by many factors, including geographical and meteorologic ingredients. In order to understand the mechanism and control it, many experts have conducted lots of researches. Many helpful insights have been achieved, but it is still very poor. Based on precipitation data measured by meteorological stations, a meaningful attempt that uses the certain climate pattern to explore basin spatial distribution of precipitation was implied in this research. Based on this consumption, the study on Wudinghe River basin in China shows that spatial distribution of precipitation is fairly non-uniform and mainly influenced by terrain and meteorologic factors.
