本章讨论山区空气污染的一般问题。描述了地形对空气污染物的空间分布和时间变化的影响，包括在稳定和对流边界层以及动态驱动条件下遇到的具体影响。数值模型、比例模型和观测研究的使用被描述为了解山区空气污染的工具。在加拿大弗雷泽河谷下游和德国莱茵河上游河谷进行的具体空气污染综合区域研究被用来说明地形影响。本章最后讨论了山区空气污染的预测方法。
In this chapter, the general problem of air pollution in mountainous terrain is discussed. Terrain effects on the spatial distribution and temporal variability of air pollutants are described including specific effects encountered in stable- and convective boundary layers and under dynamically driven conditions. The uses of numerical models, scale models, and observational studies are described as tools for understanding air pollution in mountainous terrain. Specific integrated regional studies of air pollution conducted in the Lower Fraser Valley, Canada and in the Upper Rhine Valley, Germany are used to illustrate the terrain effects. The chapter concludes with a discussion of approaches to forecasting air pollution in mountainous terrain.
