The simulation study of the interaction between aerosols and heavy air pollution weather in East China

摘要

The aerosol-radiation interaction is coupled into an online mesoscale aerosol forecasting model. The direct radiative feedbacks on heavy air pollution weather due to aerosols are simulated and studied. The preliminary results show aerosols direct radiative effects may cool the near surface atmosphere in East Asia, reduce turbulent diffusion process and further weaken low pressure system related with heavy pollution episode. All results suggests that aerosols direct radiative feedback is benefits to keep the mesoscale stable condition of the local atmosphere in East China and shows positive feedback on the keeping and developing of heavy air pollution episode in East Asia.
