NUMERICAL EXPERIMENTS OF THE SOIL TEMPERATURE AND MOISTURE ANOMALIES'''' EFFECTS ON THE SHORT TERM CLIMATE
土壤温湿异常对短期气候影响的数值模拟试验

Sensitivity experiments of soil temperature and soil moisture were carried out with IAP GCM. The anomaly domain was selected in the region of China. For soil temperature, cases with initial anomalies and fixed anomalies were studied, respectively; for soil moisture, only the initial anomalies were used. The results show that the initial soil temperature anomalies' effects disappear after 24 hours but the fixed soil temperature anomalies and the initial soil moisture anomalies have important effects on the short term climate. The influence of soil temperature anomalies is restricted mainly within the anomaly area and the southern adjacent region; the soil moisture anomalies' influence may propagate vary far away from the anomaly region after ten days.
