| 摘 要： | 分析了近50年我国北方沙尘暴的年代际变化和热盐环流(THC)的年代际变率的演变特征,发现沙尘暴与THC存在一定的联系.这种相互联系的演变过程大致是:THC与北大西洋涛动(NAO)有联系,NAO与西伯利亚冷高压有联系,而西伯利亚高压又影响北半球冷空气活动,最终影响我国北方沙尘暴的发生.结果表明,THC强(弱)→NAO弱(...

| Abstract: | In this paper,the characteristics between the decadal variation of sand-storm in north China and decadal variability of thermohaline circulation(THC) in recent 50 years are analyzed.It is found that there are some relationships between the sand-dust storm and THC.Further analyses indicate the primary process of this following relationship: THC influences on NAO,NAO on Siberia high,Siberia high on cold air activities,and then,on the sand-dust storm.The results show that when THC is strong(weak),NAO is weak(s... |
