城市空气质量数值预报模式系统及其应用

介绍了一种城市空气质量数值预报模式系统 ,该系统由气象模式 (中尺度气象模式MM5及城市大气边界层模式CBLM)和大气污染物输送扩散化学模式组成 .将模式系统应用于南京市 ,试预报结果同监测结果一致 ,表明模式具有较好的模拟性能 .模式系统试运行后的检验改进工作 ,气象资料、污染源及环境参数等质量的提高 ,预报结果检验方法的确定等都是模式系统业务化时应予以充分考虑的 .

Study on the development of numerical model system to predict urban air quality

The urban air quality prediction numerical model system is briefly introduced in this paper, which is composed of meteorology model (MM5 and CBLM) and atmospheric chemistry model. The whole model system procedure is composed of nine parts, making it easy for operation and modification. The model system has been used to predict the air quality in Nanjing city. The agreement between the prediction and the observation shows good prediction capability of the model system. The amelioration of check method, the quality improvement of meteorology data and city geography information etc should be further considered in daily prediction work.
