沿海丘陵地形区域大气环境质量预测模式体系

介绍了一套适合沿海丘陵地形条件的区域大气环境质量预测体系，它主要由局地扩散模式（ＨＰＤＭ模式，Ｍｉｓｒａ模式）、中尺度气象场模式和区域扩散模式（分段烟流模式）组成，该系统具有较快的计算速度。同时文章对气象场模式中所采用的三维准静力动力学模型在地形追随坐标下的形式进行了较完整的描述，对变换后湍流扩散项的近似取舍进行讨论并且对传统的分段烟流模式的分段烟流作了连续性定义的改进。

A Prediction System for Regional Atmospheric Environment Quality of the Coastal Hilly Topography Region

This paper introduces a set of regional atmosphere environmental quality prediction systems suitable for coastal hilly topography condition. The system is mainly composed of local dispersion model (HPDM model, Misra model), mesoscale meteorological field model and regional dispersion model (section plume model) with a relatively quicker calculation speed. Meanwhile, this paper has described the three dimension quasi static dynamics pattern under the form of coordinate conversion pursuing topography , and the selection of turbulent dispersion item after conversion. Moreover, this paper has also improved the continuity definition of plume section in tradition section plume model.
