【摘要】 利用RegCM3模式,采用NOAA的NCEP/DOE再分析资料,进行鲁中山区地形对山东平均气温和降水影响的控制试验和敏感性试验,并将试验结果与山东及其邻近地区的145个地面观测站点的实测气温和降水量进行了对比分析。结果表明:鲁中山区地形作用使鲁南,泰、鲁山南部,泰山西北部以及五莲山东南部地区降水量增加,鲁中西部、北部降水减少;使夏季平均气温在36.5°N以北增加、36.5°N以南降低。更多还原

【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.更多还原
