THE INFLUENCE OF QUASI-BIENNIAL OSCILLATION ON THE EQUATORIAL PLANETARY WAVES

From the theory of the occurrence of Quasi-Biennial Oscillation (QBO), we conclude that Kelvin wave and Rossby-gravity wave should propagate upward alternately during the different phase of the QBO. With the results of the numerical simulation, we conform this conclusion. Further more, we reasonably apply this effect on some other planetary waves, and try to find out the association between the QBO and the solar-terrestrial coupling.
