Abstract: The sensitive control experiment for impacts of the middle Shandong mountain topography on temperature and precipitation was conducted,based on NCEP/DOE reanalysis data of NOAA by using RegCM3 model.The outputs were analyzed through the comparison with the meteorological observed data from the surrounding 145 stations within or nearby the Shandong province.The results showed that the topography probably increased precipitation over the southern Shandong,the southern Tai and Lu Mountains,the northwestern Tai Mountain and the southeastern Wulian Mountain,but decreased precipitation in the middle western and northern Shandong.Mountain topography also increased summer average temperature in the north of 36.5°N,but decreased temperature in the south of 36.5°N.

Key words: The mountain area of Shandong Province, The mountain area of Shandong Province, Topography, Climatic Change, Physical mechanisms
