The meridional wind at 100 hPa level and the annual change of total ozone over the Northern Hemisphere
北半球100 hPa等压面经向风与臭氧总量年变化

The relationship between the meridional wind at 100hPa level and the annual change of total ozone over the Northern Hemisphere has been analysed by secular mean data . It is shown that; they are closely related. The north and south wind at 100 hPa level corresponds to high and low total ozone values , respectively : furthermore , the meridional wind affects the change of total ozone . It fully proves that the annual change of the total ozone is mainly influenced by the lower stratospheric circulation .
