This study investigated the second indirect climatic effect of anthropogenic aerosols including sulfate, organic carbon (OC) and black carbon (BC) over East Asia.The simulation period was 2006; the seasonal variation of the climatic response to the second indirect effect was also characterized.Due to decrease in autoconversion rate from cloud water to rain induced by aerosols, the cloud liquid water path (LWP) and radiative flux (RF) at the top of the atmosphere (TOA) changed obviously, increasing by 7.42 g/m2 and decreasing by-2.35 W/m2 in terms of domain and annual average.Both LWP and RF changed most in autumn.There were strong decreases in ground temperature in southwest China, the middle reaches of the Yangtze River in spring and autumn, when maximum cooling up to-1.5K occurred in the Chongqing district.The regional and annual mean change in ground temperature reached-0.1 K.In seasons except summer, precipitation generally decreased in most areas north of the Yangtze River, and changed little in south China.
