The features of ozone quasi—biennial oscillation in tropical stratosphere and its numerical simulation

摘要: The inlcrunnual variation of the vertical distribution ozone in tropical stratosphere and its quasi—biennial oscillation (QBO) is analyzed using HALOE data. results are compared with wind QBO. A numerical experiment carried out to study effects QBO on distribution, by (he NCAR interactive chemical, dynamical, radiative two—dimensional model (SOCRATES). Data analysis shows that location maximum mixing ratio changes meridional directions, assumes a period. motion leads column hemispheric asymmetry. closely connected zonal data also region, phase for density many times height. Numerical simulation circulation induced includes three pairs cells stratosphere, which have symmetry. transport various latitudes heights main dynamic cause Cells middle (25-35 km) play an important role producing
