| 摘 要： | 欧洲中期天气预报中心40 a的再分析资料（ERA40）对中国范围土壤湿度的表现好于美国国家环境预测中心/国家大气研究中心（NCEP/NCAR）再分析资料,尤其是在春末夏初阶段,对因融雪和土壤融冻产生的土壤湿度变化有着更好的表现.针对这一特点,分别用这两套再分析资料土壤温、湿度分布作为初始场驱动大气模式MM5,以1998...

| Abstract: | Previous studies have indicated that the European Center for Medium-Range Weather Forecasts(ECMWF) 40 years global reanalysis(ERA40) is better than the National Centers for Environmental Prediction-National Center for Atmospheric Research(NCEP-NCAR) Global Reanalysis(NCEP/NCAR) for describing the soil moisture over China,specially for the soil moisture variation due to snow melting and soil thawing at the end of spring and the beginning of summer.In this paper,two soil moisture and temperature data sets at ... |
