| 摘 要： | 本文在改进了大气环流模式NCAR CAM3.1中的土壤冻融过程参数化的基础上,模拟研究了改进的冻土过程对东亚气候模拟的影响.模拟结果分析表明,改进冻融过程参数化后,冬季欧亚大陆上大部分地区大气对地表的加热偏强,而夏季地表对大气的加热偏强,尤其是青藏高原对大气的加热作用显著增强.东亚气候对冻土过程参数化方案非常敏感,冬、...

| Abstract: | An improved frozen soil parameterization scheme is introduced and its effects on climate in East Asia are investigated by using the latest version of general circulation model(GCM) CAM3.1 developed at NCAR.Simulation results show that the improved soil freezing process leads to enhanced heating of the earth's surface by the atmosphere over most parts of Eurasia in winter,while it leads to enhanced heating of the atmosphere by the earth's surface in summer,especially the abnormal heating is significantly str... |
