南京气象学院简单空气质量数值预报模式系统研究

建立了一个简单空气质量数值预报模式系统，该系统由中尺度数值预报模式（MM5）、Pielke中-β尺度气象模式和Euler大气平流—扩散模式以及Erisman干沉降模式组成。该模式系统具有资料获取容易、结构简单、使用方便、运行稳定等特点。应用该模式系统对南京、沈阳等城市的SO2浓度值进行了预报试验，结果表明，该模式系统能够较为准确地模拟城市范围内污染物的时空分布，可用于城市空气质量预报业务，现已在上海和南京的空气质量预报业务中得到应用。

Study on the Simple Numerical Forecasting Model System of Air Quality in Nanjing Institute of Meteorology

A simple air quality numerical model system (short for SAQMS) was built. It is composed of mesoscale numerical forecasting model(MM5), pielke mid-β scale meteorological model, euler atmospheric advection-diffusion model and erisman dry sink model. It has characteristics of capturing data easily, simple framework, convenient use and stable operation. This model system was used to forecast and examine SO2 concentration distribution of Nanjing and Shenyang. The results showed that it could simulate the temporal-spatial distribution of contamination in city area relatively well and truly, it could be used in the forecasting operation of air quality. Now, it has applied in air quality forecastion operation in Shanghai and Nanjing.
