| 摘 要： | In this paper, a two-dimensional primitive equation model, coupling dynamical, radiative andphotochemical processes, is used to simulate the quasi-biennial oscillation (QBO) in ozone. TheQBO in total ozone has been successfully simulated when the forcing of equatorial stratosphericQBO in zonal wind is imposed. The simulated characters of QBO in ozone are in close agreementwith those observed. We further analyzed the mechanism of formation and maintenance of QBO inozone. In the different phases of QBO in equatorial stratospheric wind field, the global circulationhas so great difference that it makes the effects of advection transfer and eddy transfer present aquasi-biennial periodical variation. Chemical effect and dynamical effect are basically out-of-phase.They together form and maintain the QBO in ozone. Total variation rate is a tiny difference of thetwo large amounts. At the lower level of middle-high latitudes, however, it has a phase differenceof about 1-2 months between dynamical and negative chemical effects, where the dynamical effectis comparatively greater. QBO in ozone has no clear counter effects on atmospheric circulation. The experiment resultsshow that the effects of QBO in ozone on temperature field and wind field are very small.

| Abstract: | In this paper, a two-dimensional primitive equation model, coupling dynamical, radiative and photochemical processes, is used to simulate the quasi-biennial oscillation (QBO) in ozone. The QBO in total ozone has been successfully simulated when the forcing of equatorial stratospheric QBO in zonal wind is imposed. The simulated characters of QBO in ozone are in close agreement with those observed. We further analyzed the mechanism of formation and maintenance of QBO in ozone. In the different phases of QBO in equatorial stratospheric wind field, the global circulation has so great difference that it makes the effects of advection transfer and eddy transfer present a quasi-biennial periodical variation. Chemical effect and dynamical effect are basically out-of-phase. They together form and maintain the QBO in ozone. Total variation rate is a tiny difference of the two large amounts. At the lower level of middle-high latitudes, however, it has a phase difference of about 1-2 months between dynamical and negative chemical effects, where the dynamical effect is comparatively greater. QBO in ozone has no clear counter effects on atmospheric circulation. The experiment results show that the effects of QBO in ozone on temperature field and wind field are very small. |
