| 摘 要： | 利用NCEP/NCAR再分析资料计算了1998年5～6月区域角动量收支的主要分量,对比分析了范围较大的欧亚区域角动量矩和限制在欧亚大陆范围内的喜马拉雅山角动量矩的差异,发现两者有很好的相关,限制较小范围的计算表明,喜马拉雅山山脉力矩的作用显著。角动量收支项占较大量级的山脉力矩和摩擦力矩,并与梅雨锋区域的700hPa高度... |

| Abstract: | Using the reanalysis data,the main torques of atmospheric angular momentum(AAM) in May and June 1998 were calculated.Firstly,comparing with the difference between Eurasian and Himalaya torques,it is found that the torques between the two regions are well correlated and the one in smaller area well focuses on Himalaya Mountain.There was significant positive correlation between 700 hPa height field in Meiyu frontal zone and the regional friction torque which leads the 700 hPa before 3 days.Their lag correlati... |
