In this paper, we examine the direct effects of sulphate and black carbon (BC) aerosols in China on East Asia monsoons and its precipitation processes by using the Community Atmosphere Model (CAM) 3.0 model. It is demonstrated that sulphate and BC aerosols in China both have the effects to weaken East Asia monsoons in both summer and winter seasons. However, they certainly differ from each other in affecting vertical structures of temperature and atmospheric circulations. Their differences are expected because of their distinct optical properties, that is, scattering versus absorbing. Even for a single type of aerosol, its effects on temperature structures and atmospheric circulations are largely season-dependent. Applications of T-test on our results indicate that forcing from BC aerosols over China is relatively weak and limited. It is also evident from our results that the effects of synthetic aerosols (sulphate and BC together) on monsoons are not simply a linear summation between these two types of aerosols. Instead, they are determined by their integrated optical properties. Synthetic aerosols to a large degree resemble effects of sulphate aerosols. This implies a likely scattering property for the integration of BC and sulphate aerosols in China.
