| Abstract: | In the context of wavelet technique and coherence analysis the existence of east Asian monsoon QBO is investigated together with its relation to ENSO variability. Results suggest that the monsoon exhibits noticeable QBO but the periods and amplitudes show significant change on an interdecadal basis with the QBO evolution in close relation to an El Nio episode; the western Pacific warm pool serves as a key area connecting the monsoon and ENSO cycle in such a way that the strong QBO winter monsoon first gives rise to a teleconnection wavetrain, followed by anomaly occuring in the warm pool that is then moving eastward, exerting effect on equatorial eastern Pacific SST, causing El Nio happening; the monsoon QBO is responsible for strong seasonal ENSO phase locking and for its warm phase lasting one year or so. |
