摘　　要：为更好地了解长三角地区台风登陆前后臭氧廓线变化情况,本文选用2018年登陆长三角地区的三个台风——单台风“安比”以及双台风“潭美”和“康妮”登陆前后卫星臭氧廓线数据,研究这些台风登陆长三角地区前后臭氧廓线的变化情况,得出以下结论:1) 台风影响长三角地区臭氧垂直输送,导致臭氧廓线在台风登陆前后不同;2) 双台风“潭美”和“康妮”与单台风“安比”影响长三角臭氧廓线变化趋势大体相反:双台风来时使得对流层中上部以及平流层中下部臭氧浓度升高,其余部分臭氧浓度降低,而单台风“安比”来时使得长三角地区对流层以及平流层中下部臭氧浓降低、平流层中上部臭氧浓度上升;双台风登陆后,离地面最近的臭氧浓度比台风登陆前低,而单台风“安比”登陆后,同一层的臭氧浓度比台风登陆前高。For better understanding the changes of the Ozone profiles before and after landings of Typhoon, this paper selected the satellite ozone profile data before and after landings of three ty-phoons—single Typhoon “Ampil” and binary typhoons “Trami” and “Kong-rey” in the Yangtze River Delta region in 2018 to study the changes of ozone profiles in the region and obtained the following conclusions: 1) Typhoon had impacts on the vertical ozone exchanges in the Yangtze River Delta, and led to different ozone profiles before and after typhoon landing;2) The binary typhoons “Trami” and “Kone-rey” and the single typhoon “Ampil” affected the ozone profile in the Yangtze River Delta in opposite ways: After the binary typhoons’ landing, the ozone concentration in the upper and middle troposphere and the lower and middle stratosphere increased, while the other part of the ozone concentration decreased. After the single typhoon “Ampil” landed, the ozone concentration in the troposphere and the lower and middle stratosphere in the Yangtze River Delta decreased, and the ozone concentration in the upper and middle stratosphere increased;After the binary typhoons’ landing, the ozone concentration in the layer closest to the ground was lower than that before the binary typhoons’ landing, while after the single typhoon Ampil landed, the ozone concentration in the same layer was higher than that before the typhoon’s landing.
