Abstract:
The correlation between tropic sea surface temperature of global and NAO and ENSO events were studied by means of bivariate wavelet analysis. Results show that the correlation between tropic SST and ENSO cycle on the time scales of 2 to 7 years and over 30 years is apparent with the maximum variance contribution appearing at the period of 4 years. The most striking correlation between North Atlantic SST and ENSO events was found on the time scales of 4 years and 15 years. There is weak anticorrelation between NAO and ENSO events on the time scales of 2 to 7 years and 10 to 24 years, and weak correlation on over 25 year scale.
