| Abstract: | Fourier power spectrum and wavelet power spectrum are used to analyze the time series of sea surface temperature anomaly in equatorial Pacific and southern Pacific,and the characteristics in time and frequency domain are derived.The result indicates that the time series of sea surface temperature anomaly contains period signal of two-year to six-year. |
