Abstract: Topography has significant influence on the climate. It is still unclear of what influence the regional topography over southeast China may have on the climatalogical distribution of precipitation. In this paper, the mean (1951 - 1980) precipitation data in the surface observational network are used to study the influence of topography over the region. The results showed that there exists a maximum rainfall belt on the east and west side each of the Zhejiang - Fujian Hilly Land and the south and north side of Nanling. From the seasons in which the maximum rainfall belts appear, it is clear that their occurrence is related to the upslop of the topography. Discussing to various mechanisms of topography, a suggestion about the influence is made that the enchancement of the precipitation is through the topographical forcing to the precipitating weather systems.
