A Numerical Study of Direct Radiative Forcing Due to Black Carbon and Its Effects on the Summer Precipitation in China
黑碳气溶胶直接辐射强迫及其对中国夏季降水影响的模拟研究

The global mean distribution and seasonal changes of direct radiative forcing due to black carbon(BC)at the top of atmosphere(TOA)and surface and the effect of cloud on BC direct radiative forcing have been investigated by using the CAM3(Community Atmosphere Model Version 3)developed by NCAR.Then,the influence of BC on summer precipitation in China is discussed.The results show that there exist obviously seasonal changes in the global mean distribution and intensity of direct radiative forcing due to BC at ...
