Abstract:

The accuracy of the RegCM model simulation has been verified for the regional climate elements in many studies in China. However, the default data sources of the system usually lack the localized characteristics, especially for the aerosol emission inventory. The biomass sources have seasonal variability, whereas the anthropogenic sources are fixed unchanged, which greatly neglect the aerosol climate effects of the anthropogenic sources. The climate effect of anthropogenic black carbon aerosol was compared and analyzed under different scenarios, applying the emission source inventory (calculated by MEIC model) provided by Tsinghua University. The results showed that the addition of black carbon aerosol could significantly change the radiative forcing, temperature, rainfall and black carbon aerosol column contents in China, with obvious seasonal variation characteristics. With the variation of seasons, different climatic factors had different increase/decrease tendency: the temperature increased from south to north areas; the rainfall increased in south areas and decreased in north areas; and the black carbon aerosol column was centered on the southern industrial agglomeration areas.

Key words: RegCM, climate effect simulation, emission source, black carbon aerosol
