利用2006年区域气候模式RegCM3和Streets气溶胶排放源清单,在原模式中引入间接气候效应模块,改进云降水方案,对硫酸盐气溶胶的时空分布、辐射强迫效应进行了模拟研究。结果表明：硫酸盐气溶胶辐射强迫有明显季节变化;直接效应使地表温度降低,冬春季大值区出现在四川盆地,夏季大值区出现在华北平原。对降水的影响,主要表现在西南—东北水汽输送带上降水减少;其间接气候效应主要表现在使南方地区温度上升、北方地区温度下降;珠江流域和黄河流域降水减少,长江流域和东北地区降水增加。总的来说,直接效应大于间接效应。

Based on the regional climate model version 3（RegCM3）and emission inventory data by Streets in 2006,the indirect climate effect module was inducted into the RegCM3.Cloud precipitation scheme was ameliorated.The temporal and spatial distributions of the sulfate aerosol and radiative forcing were simulated.The results indicate that the seasonal variation of radiative forcing of the sulfate aerosol is significant.For temperature,the direct climate effect leads to the surface temperature decreased.The areas with large forcing appear in the Sichuan Basin in winter and spring and in the plains of the north China in summer,respectively.For precipitation,the direct climate effect causes precipitation reduced along the belt of the water vapor transport across southwest to northeast.The indirect climate effect is to increase temperature in the south and decrease in the north,while it decreases the precipitation in the Pearl River valley and the Yellow River valley and increases in the Yangtze River valley and the northeast China.In general,the direct climate effect is stronger than the indirect effect.
