Abstract: Some studies have shown that the positive radiative forcing (0.1 W/m2) caused by black carbon (BC) could not only be an important impact factor on global warming, but also affect multiple parameters of the climate system, such as atmosphere circulation, precipitation, etc. Recently, the research of BC has extended to the fields of carbon cycle, and the interactions of BC aerosols with the abnormity of atmosphere circulation, and of the surface of BC particles with active gas species, etc. New progresses in the above research fields are reviewed in this paper.

Key words: black carbon aerosol, climate effect, carbon cycle, atmosphere circulation, heterogeneous reaction
