| 摘 要： | 主要综述中国科学院大气物理研究所自主开发的嵌套网格空气质量预报模式系统(NAQPMS,Nested Air Quality Prediction Modeling System)的历史发展与应用情况.模式发展伊始为欧拉污染物输送实用模型,利用其研究东亚硫氧化物的跨国输送问题,得出中国对于周边国家的输送量不大的结论; 在系统中嵌入适合东亚的起沙机制模块,用来模拟沙尘发生、输送及沉降等过程,估算亚洲大陆沙尘气溶胶对海洋地区的输送与沉降通量,为研究海洋生物地球化学循环提供基础数据; 利用该系统研究沙尘及其土壤粒子对酸雨的中和作用,发现沙尘输送对东亚酸雨的分布影响很大; 发展城市尺度高分辨率气象和空气质量预报技术,使模式水平分辨率达到500 m,并应用于台北高浓度臭氧和PM10的模拟; 研究和集成区域及城市尺度大气污染预报理论和模拟技术,研制成目前的嵌套网格空气质量预报模式系统,以探讨不同尺度各种污染(如沙尘暴、城市光化学烟雾、酸雨、高浓度悬浮颗粒物等)的变化规律.在模式系统中初步建立资料同化模块,开展大气化学成分及沙尘输送模拟的资料同化研究.系统已经在北京、上海、深圳、郑州等城市环境监测中心实施空气质量的实时预报.未来,系统将集成到全球环境大气输送模式(GEATM),以实现从城市群到全球具有双向耦合功能的模式系统.

| Abstract: | Development and application of Nested Air Quality Prediction Modeling System(NAQPMS),which is independently developed by IAP/CAS,have been introduced in this paper.At first,the system is developed as a practical 3-D Eulerian transport model for pollutants to evaluate transboundary transport of sulfur dioxides and sulfate in East Asia.The simulations indicate that limited sulfur from China is transported to neighboring countries.A deflation module is designed and applied to East Asia,which is embedded in the system.On the basis of the deflation module,dust transport numerical prediction is carried out.The system is used to simulate the process of emission,transport and deposition of dust.The fluxes for transport and deposition of dust from Asian mainland to ocean are also calculated and provide basic data for researching halobios geochemistry cycles.Using the model system for regional scale,the influence of dust transport on distribution of acid rain in East Asia is calculated.High resolution meteorology and air quality prediction techniques are developed in the system for urban scale with a horizontal resolution of 500 m,which is applied to simulating high-concentration ozone and PM10 in Taipei.At present,NAQPMS is designed based on integration of prediction theories and simulation methods for regional and urban scales,and the system can study many air pollution problems for various scales,including dust storm,acid rain,high-concentration suspended particulate and photochemical smog.An elementary assimilation module on atmospheric chemical element and dust has also been built in the system.Currently,the model system has been used to forecast the real-time air quality of a region or city,e.g.,Beijing,Shanghai,Shenzhen and Zhengzhou.In future,the model system will be coupled into the Global Environment Atmosphere Transport Model(GEATM),to implement the bidirectional coupling system from cities to global scales. |
