摘　　要：Based on the vertical ozone reanalysis data and total ozone column data derived from the European Centre for Medium-Range Weather Forecasts,the spatial and temporal distribution characteristics of ozone on each isobaric surface in the troposphere over the Northwest Pacific Ocean were analyzed,and the backward trajectory method was used to track the influence of typhoon on the distribution of ozone.The results show that the updraft near the typhoon center transported the air with low O_(3)content in the lower layer to the upper layer,which reduced O_(3)content in the upper layer and formed a low-value area of O_(3).The variation trend of total ozone column in the regions where typhoons"Megi"and"Fengshen"occurred was analyzed by the case analysis method.It is found that there was a low-value area of total ozone column anomaly near the typhoon center,and there was a certain correlation between typhoon intensity PDI and total ozone column anomaly at the development and maturity stages of typhoons.
