2015-2016河北省中南部污染物输送技术研究

Study on contaminants delivery in central south of Hebei province from 2015 to 2016

利用河北省环保局环境监测站提供的AOI值逐日数据,基于Hysplit模式对河北省不同区域、不同高度的气团进行聚类分型,得到污染季影响河北省的主要气团。统计结果表明:2015年和2016年的11次重污染过程气团轨迹主要分为以下4类,南部、西部、东部和区域间短距离输送型,其中重污染过程中,以南部和区域间短距离输送为主,西部和东部输送也有一定的影响。

Based on the daily data of AOI provided by Environmental Monitoring Station of Environmental Protection Bureau of Hebei Province, the air mass of different regions and altitudes in Hebei Province was clustered and classifed based on Hysplit model, and the main air mass affected Hebei Province during the polluted season. The statistical results show that the air mass trajectories of 11 heavy polluting processes in 2015 and 2016 are mainly divided into the following four categories： short, medium, short and long Transport-based, the western and eastern transport also have a certain impact.
