摘要：
The influence of El Nino on aerosol concentrations is investigated for eastern China over period 1986-2006. Result suggests that the influence of El Nino on aerosol concentration differs between events. The 1987/1988 El Nino event decreased the aerosol concentrations during the mature and decay spring of the event; however, an anomalous northern-increase and southern-decrease dipole structure occurred during the decay summertime over eastern China. In contrast, the event of 1997/1998 was associated with an evident increase in aerosol concentration over its lifespan. These anomalous aerosol concentrations are mainly caused by circulation changes associated with El Nino events.
