The evolution of summer rainfall quasi-biennial oscillation (TBO) is studied over eastern China using monthly mean rainfall data of China 160 stations from China Meteorological Administration.

On the basis of analyzing the data of group sunspot numbers, zonal wind at the equatorial stratosphere, tropical cyclone (TC) activity over the west of North Pacific (WNP), the relationship between the quasi-biennial oscillation (QBO) of equatorial stratospheric zonal wind and tropical cyclone over WNP is discussed.

In this papar,the possibility of a relation among Quasi-Biennial Oscillation(QBO)of zonal winds in the equatorial stratosphere,sunsport Wolf number and SST s in the eastern Pacific during the same interval are analyzed.

Analysis has been done on quasi-biennial oscillation (QBO) in inter-annual ozone variation over the Tibet, in comparison with QBO over the tropics and non-mountain region at the same latitudes of the Tibet.

ENSO in the scale of quasi-biennial oscillation (QBO) is diagnostically analyzed in this paper.

For the barotropic potential vorticity equation (named the barotropic model) on a β-plane channel its solution is a stationary, wave-like pattern under a certain thermal forcing, while a quasi-periodic oscillation between two essential flow patterns appears if north-south thermal heating and wave-like topography are added as the .
