摘　　要：在Ｔ１０６Ｌ１９谱模式中引入青藏高原土壤温度和湿度新近资料，改进模式中的地表物理过程参数化方案，作了中期预报数值试验，结果表明：青藏高原土壤温度和湿度对高原本身及我国东部、东北地区高度场和降水预报有一定影响，改进土壤参数能够有效提高模式的预报结果。Through comparison tests by changing the temperature and moisture data of Tibetan Plateau T106 model, and improving its surface parameterization scheme, the influences on medium forecast are discussed. The results indicate that the soil temperature and moisture of Tibetan Plateau have some effects on the forecasts of Plateau itself and China, especially the precipitation in the North East of China, modifying soil parameter can improve the forecast effectively.
