Impact of Planetary Wave on the Stratospheric Residual Circulation
行星波波动对平流层剩余环流的影响

Using the global ECMWF/ECR-40 reanalysis data and calculating the residual velocities,the distribution characteristic of the residual circulation are analyzed.And the planetary wave amplitudes of waves 1 and 2 were also calculated by the geopotential height data.Then the changes of the residual circulation were analyzed in different activity intensities of planetary wave,as well as the change after wave 1 transformed into wave 2 or wave 2 transformed into wave 1.The results showed that there was a nice cohe...
