Abstract:

Lanzhou is one of the most polluted cities in China SO2 concentration has evident seasonal variability It is generally within the second-level criterion 0.15 mg m sub-3 in spring, summer, and fall, but is much higher than the second-level criterion and sometimes reaches mid level pollution API 200 in winter Meteorological conditions low winds, stable stratification are found to be important for the SO2 pollution Observational and modeling studies conducted in this study show a close connection between the static stability and the SO2 pollution of Lanzhou China in winter This study also shows the capability of coupled RAMS-HYPACT on air-quality prediction.
