摘要
为加深对台风和环境空气质量关系的认识,以1604号台风"妮妲"和1608号强热带风暴"电母"为例,通过分析南宁市常规地面气象要素、天气场、气流后向轨迹、边界层高度、台风路径等资料,探讨移动过程中台风中心与南宁距离以及其与AQI的关系,结果表明,"妮妲"中心与南宁市测距为938~1 939 km时,南宁处于台风外围下沉气流影响区域,实时AQI有明显上升;测距小于311 km受台风环流影响,实时AQI明显下降;"电母"中心与南宁市测距为小于324 km时,实时AQI明显下降,台风类型不同对南宁的气象和环境空气质量的影响程度也有较大差异。
In order to deepen the understanding of typhoon and the relationship of environmental air quality,taking the typhoon（ No. 1604 Nida） and strong tropical storm（ No. 1608 Dianmu） as example,through analysis regular surface meteorological elements,weather field,airflow back direction trajectory,height of boundary layer,and typhoon paths in Nanning these information,a moving process was discussed,the distance of the storm center in Nanning,some cities in Guangxi and its relationship with AQI. The result shows that while Nida＇s center ranging Nanning distance from 938 km to 1 939 km,Nanning is located in the area where was affected by the downward flow from storm periphery,real time AQI has obviously increased. While ranging distance less than 311 km and was affected by the storm circulation,real time AQI has obviously decreased. While the distance of Dianmu＇s center and Nanning city less than 324 km,real time AQI was significantly reduced. Different types of typhoon have different extent of impact on Nanning city.
