摘要
2020年,泰州市大气PM_(2.5)中度、重度污染日主要集中在1月和12月,共计8次污染过程19个污染日,3次PM_(2.5)重污染过程天气背景总体相似。对泰州市2020年1月12—14日大气PM_(2.5)重度污染过程展开分析,结果表明,该次污染是典型的区域污染,污染过程中都伴随着冷高压南下带来的污染物区域输送过程,前期的区域输送、后期的回流叠加本地污染物累积造成了本次PM_(2.5)的持续污染。
In 2020,Taizhou atmospheric PM_(2.5) moderate and severe pollution days are mainly concentrated in January and December,with a total of 8 pollution processes,19 pollution days and 3 PM_(2.5) severe pollution process.The weather background of heavy pollution process is generally similar.Atmospheric PM_(2.5) severe pollution process in Taizhou from January 12 to 14,2020 are analyzed.The results show that this pollution is a typical regional pollution.The pollution process is accompanied by the regional transportation of pollutants brought by cold and high pressure southward.The regional transportation in the early stage and the backflow in the later stage are superimposed with the accumulation of local pollutants,resulting in the continuous pollution of PM_(2.5).
