Abstract
A fully coupled meteorology-chemistry-aerosol model (WRF-Chem) is used to assess the impacts of emission controls and perturbations on a summer intense convective precipitation event from August 9-11 during the 2008 Olympic Games. More realistic aerosol representation of aerosols in the model and the fully coupled aerosol-radiation-cloud feedbacks lead to a better prediction of precipitation, compared with the satellite retrieval. The emission scenario simulations suggest that even small perturbations in the concentration and/or compositions of aerosols can lead to either enhancement or suppression of this summer intensive precipitation event. Detailed process analyses are carried out to diagnostic the key process or mechanism that triggers the changes in precipitation due to the emission perturbation.
