Abstract:
This article observations of atmospheric pressure and tropospheric ozone concentrations in East Asia during 2001-2015 were used, the two indices that best represent the activity of East Asian monsoon are selected and calculated, applicated the statistical analysis and case study methods, East Asia monsoon and typhoon preocess in the relationship between ozone levels were discussed.Following conclusions: There is a positive correlation between the SMC summer monsoon index and the tropospheric ozone concentration in the 40 o N to 50 o N, and a negative correlation with the Equator.There is a positive correlation between the IWT winter monsoon index and the tropospheric ozone in the the South China Sea to western Pacific.In areas affected by the strong rise in the typhoon center airstream most frequent low ozone concentration, ozone concentration is high in areas most affected by the subsidence air flow from typhoons.
