摘要

We successfully developed a set of technical methods constructing fine climatic analysis field for regional precipitation considering terrain influence based on PRISM monthly climatic precipitation analysis field and DEM. By using harmonic analysis and Shepard inverse distance interpolation,we quantitatively analyzed precipitation observation data at 68 reference weather stations of Zhejiang Province in recent 50 years,and established climatic analysis field of daily precipitation at 1 km grid of Zhejiang Province considering terrain influence. Systemic cross-examination of the method was conducted. Result showed that the established fine climatic field for precipitation could reproduce rapid seasonal evolution characteristics of precipitation induced by monsoon migration and typhoon landing with better quantitative accuracy.
