廊坊市霾天气湍流运动特征量统计分析

Statistical Analysis of Turbulent Motion Characteristics in Haze Weather in Langfang City

旨在对霾天气时大气边界层湍流运动进行深入分析,为大气污染防治提供依据,利用统计学方法对2016~2017年廊坊市霾天气时风脉动数据进行分析,得到轻微霾、轻度霾、中度霾、重度霾不同级别霾及静稳霾、混合霾、风霾不同类型霾时大气湍流物理量特征值,根据各物理量建立起霾的分类与分级方法,从湍流运动角度为霾的预报提供一些依据。

The purpose of this paper is to analyze the turbulent motion of atmospheric boundary layer in haze weather and provide basis for prevention and control of atmospheric pollution.The data of wind fluctuation during haze weather in Langfang City from 2016 to 2017 were analyzed by statistical method.The physical characteristics of atmospheric turbulence in light haze,light haze,moderate haze,severe haze with different levels and static haze,mixed haze and wind haze with different types of haze were obtained.The classification and classification methods of haze were established according to the physical quantities,which can provide some basis for the prediction of haze from the aspect of turbulent motion.
