On the Relation Among the Solar Activity,The Quasi-Biennial Oscilliation in the Eaquatorial Stratosphere and El Nino

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. The band filter and the wavelet method which are capable of finding local periods and amplitudes are used in the data processing. It is shown that the coherence estimates between the series of QBO in Wolf and in lower tropical straosphere are of order of -0.6. A possible dynamical explanation for skip a beat of QBO linked El Nino suggested by Angel and Gray is presented. Solar activity is a hypothetical mechanism of this skip.
