研究了1986-2006年厄尔尼诺对中国东部地区气溶胶浓度的影响。结果表明，厄尔尼诺对气溶胶浓度的影响在不同事件之间是不同的。1987/1988年厄尔尼诺事件使春季气溶胶浓度下降，但在夏季衰减期间，中国东部地区出现了异常的北方增南减偶极子结构。相反，1997/1998年的事件与其寿命期间气溶胶浓度的明显增加有关。这些异常气溶胶浓度主要是由厄尔尼诺事件引起的环流变化造成的。
The influence of El Niño on aerosol concentrations is investigated for eastern China over period 1986–2006. Result suggests that the influence of El Niño on aerosol concentration differs between events. The 1987/1988 El Niño 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 Niño events.
