Abstract
Based on the data from the Semi-Arid Climate Observatory and Laboratory (SACOL) during the period from 10 April 2010 to 11 April 2010,experimental simulation of dust aerosol was carried out using WKF-Chem with resolution 10 km,3 km and 1 km. Two boundary schemes (YSU and MYJ) were used respectively in each case. Tne results showed that: all cases with different resolution represented similar variation tendency with the observation,indicating the capability of WRF-Chem in the dust aerosol simulation. However,in the complicated terrain condition,the case with higher resolution did not necessarily get a better result. In this experiment,the case with MYJ resulted of a higher accuracy,indicating that the results of simulation using MYJ scheme has good agreement with the observation when the heat flux is not the decisive factor in the weather process.关键词
