由于小风对污染事件的潜在影响，以及与中等风速和大风条件相比边界层结构、湍流和扩散的特殊性，常规的稳态高斯烟流模式在这种条件下具有局限性，建立适用于小风条件的大气扩散模式具有重要的理论和实际意义。本文回顾了近年来小风条件下大气扩散模式的建立和发展，从较简单的解析模式到复杂的数值模式，并对不同模式的参数化方案、与示踪物实验的比较结果、适用性和不足之处进行了总结。综合考虑不同模式的优劣，在应用方面有利于根据实际情况选择合适的模式，在模式开发方面，有助于建立更加完备的大气扩散模式。

Considering the potential influence of low wind speed condition on pollution episodes , and the differences of PBL structure, turbulence and dispersion under this condition and those under moderate and strong wind conditions , the conventional steady state Gaussian plume model has encountered limitations under low wind speed condition.Hence, developing atmospheric dispersion models suitable for weak wind condition is significant both theoretically and practically.This paper has reviewed the es-tablishment and development of atmospheric dispersion models applied under low wind speed condition in recent years , from sim-ple analytical models to complex numerical models.The parameterization schemes of various models, comparisons between simu-lations and tracer experiments, and the applicability and shortcomings of the models are summarized .Taking into account of the advantages and disadvantages of various models can be useful for choosing a suitable model according to the actual conditions from the applying perspective.From the viewpoint of model development, it will be conductive to establish a more comprehensive at-mospheric dispersion model.
