Relationship between Variability of the Regional AAM Torque and Synoptic Scale System over East Asia in May and June 1998
1998年5～6月区域大气角动量收支与东亚天气尺度系统变化

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...
