本文讨论了国家气候中心第二代大气环流模式BCC_AGCM2.0.1和加拿大气溶胶理化模式CAM所组成的耦合模式系统对5种典型气溶胶（硫酸盐、黑碳、有机碳、沙尘和海盐）和气候要素的模拟效果。结果表明，耦合系统对5种典型气溶胶的模拟总体上比较合理，尤其是对硫酸盐、沙尘和海盐的模拟比BCC_AGCM2.0.1原有的月平均气溶胶资料有很大的改进。耦合系统模拟的全球平均气候态参量与观测/再分析资料比较一致，在总云量、陆地表面温度和降水等方面要略优于原月平均气溶胶资料的模拟结果。耦合系统对沙尘和海盐气溶胶模拟的改进使得撒哈拉沙漠和南半球中纬度海洋大气顶净太阳辐射的模拟也有所改进，而这将直接影响地表温度尤其是陆地表面温度。而不同气溶胶方案在赤道海洋上引起的云反馈不仅引起辐射的改变，还将对降水产生明显影响。

Using the coupled model system of the second generation Global Circulation Model of the National Climate Center (BCC_AGCM2.0.1) and Canadian Aerosol Model (CAM), the simulation of five typical aerosols (sulfate, black carbon, organic carbon, soil dust, and sea salt) and possible effects on the modeled climate are discussed in this paper. The results show that in general, the coupled system simulates the five aerosols reasonably well, and there are obvious improvements in sulfate, dust, and sea salt aerosols compared to the original monthly mean aerosol data used in BCC_AGCM2.0.1. The climatic statistics simulated by the coupled system mainly agree well with observational/reanalyzed data, and are a little better than the monthly mean aerosol data in terms of the total cloud amount, land surface temperature, and precipitation rate. The enhanced representation of dust and sea salt improves the simulation of net solar radiation at the top of the atmosphere in the Sahara Desert and mid-latitude ocean in the Southern Hemisphere and also affects the land surface temperature. The cloud feedback above the tropical ocean caused by the change in aerosol scheme not only alters radiation but also markedly influences precipitation.
