摘要
2021年6月4~7日青岛市区空气质量降为O_(3)轻度至中度污染,污染过程呈现持续时间长、污染程度较重的表现特征。污染期间大气扩散条件整体不利,且近地面高温、强太阳辐射、弱风等气象条件,有利于O_(3)生成且易导致污染累积。高空有较明显O_(3)污染输送至地面的情况,后向轨迹显示污染气团来自苏北区域。O_(3)污染控制的重点是大型道路运输车辆、加油(气)站、石油液化气挥发以及石化等工业企业的工艺生产过程。
From June 4 to 7,2021,the air quality of Qingdao urban area falls to O_(3) mild to moderate pollution,and the pollution process was characterized by long duration and heavy pollution.During the pollution,atmospheric diffusion conditions were generally unfavorable,and near-surface high temperature,strong solar radiation,weak wind and other meteorological conditions were conducive to O_(3) generation and pollution accumulation.There is obvious O_(3) pollution transported to the ground at high altitude,and the backward trajectory shows that the polluted air mass comes from northern Jiangsu.The focus of O_(3) pollution control is the process production process of large road transport vehicles,gas stations,liquefied petroleum gas volatilization,petrochemical and other industrial enterprises.
