CONTRIBUTION OF NON-ZONAL COMPONENT OF OZ ONE DISTRIBUTION IN RESONANT EXCITATION OF ATMOSPHERIC WAVES

Tidal theory analysis and 2D numerical modeling of wave structure show the possibility of resonant Rossby waves excitation for zonal wavenum ber m = 1. The non-zonal component of ozone distribution and 27-days o scillations of solar UV radiation contribute in the source of excitati on. The model equations are the quasigeostrophic vorticity equation, t he energy conservation equation and the continuity equation. Model run s show that large-scale transient waves may be really generated in the middle atmosphere when atmospheric resonant characteristics do not va ry dramatically. So the energy of a weak perturbation in solar activit y may be accumulated in the Earth's atmosphere as Rossby wave motions. These waves look like barotropic motions and depend on zonal wind and characteristics of solar 27-days oscillations.
