Li Yaohui, Sun Guowu, Zhang Liang, Duan Haixia. The Relationship between Decadal Variation of Sand-Dust Storm in North China and Decadal Variability of North Atlantic AirSea System[J]. Advances in Earth Science, 2011, 26(6): 624-630.
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 sanddust storm. The results show that when THC is strong (weak), NAO is weak (strong), Siberia and north winds in surface are strong (weak), sanddust storms are more (less). Moreover, a remarkable variation from the end of the 1970’s to the beginning of 1980’s is also found that THC, Siberia high and north wind changed from strong to weak, NAO from weak to strong and sanddust storm in north China obviously decreased.
