3种常见拉格朗日大气污染扩散模型的理论与应用研究

A REVIEW OF THE LAGRANGIAN DIFFUSION MODEL FOR ATMOSPHERIC POLLUTION

拉格朗日扩散模型是目前常用的空气质量模型之一,对拉格朗日扩散模型在大气环境质量中的应用与研究的总结有助于进一步提高空气质量模型的预报水平,改善环境空气质量。对当前应用较多的3种拉格朗日扩散模型CALPUFF、HYSPLIT-4和TAPM进行归纳总结,介绍了3种模型的发展历程以及理论基础,概括了不同模型的验证情况与在不同情况下的应用结果,并对3种模型的局限与发展提出了建议。对不同拉格朗日扩散模型的总结研究,可以为环境污染物的预测模拟提供进一步的研究参考方向,并为环境工作者提供一定的参考。

Lagrangian diffusion model is one of the most-widely used air quality models.Thus,a detailed summary of the applications of the Lagrangian diffusion model in the estimation of the air quality helps to raise the forecast skill of the model and also improve the air quality.In this paper,we made a thorough review of three Lagrangian diffusion models(CALPUFF,HYSPLIT-4 and TAPM)that were mostly used at present.We introduced the evolution history of the three models as well as their theoretical foundation.Validations of these models and the applications were also given.We also discussed the limitations and the future development of these models.The summary of these Lagrangian diffusion models in this paper was able to provide a guideline for the simulation and forecast of the pollutant diffusion,which could help researchers solve the environmental problems.
