MM5模拟数据在质量模型AERMOD中的应用评价

Evaluation on the Applications of Stimulated Data from MM5 in Air Quality Model AERMOD

把中尺度气象模式MM5的模拟数据输入到AERMOD中,以一次模拟为例表明:①MM5模拟的地面气象数据风向频率偏差较大,日平均温度和风速变化趋势与实测基本一致,模拟值偏大;②模拟探空数据和实测地面气象数据AERMOD预测结果与采用实测气象数据的相比有较好的一致性,模拟地面和气象数据的预测结果与实测气象数据的预测结果相比误差较大。

Using the simulated data from mesoscale meteorology model MM5 in AERMOD, a simulation as example indicates that：（1）The deviation of the simulated wind frequency is big in contrast with observation, the change tendency of daily average temperature and wind speed is basically consistent with observation, the simulated value is bigger; （2）The AERMOD results of using the simulated meteorological sounding data and the observational ground meteorological data is good in contrast with using the observational data, the results of all using the simulates meteorological data form MM5 have a large deviation.
