In this paper, the theory of the cross-coupled correlation-resonance of two wave spectra is used to study the interaction between Antarctic sea ice and ENSO events. It is found that : (1) The principal period of the correlation time series oscillation is usually coincident with the principal period of sea ice itself. If the same periods of two elements were in resonance, the correlation oscillation period would be more significant. (2) The sea ice of the Ross Sea area with its principal period of quasi-11 years has a strong cross correlation oscillation with SSTA of Nino 4. Their common period produces a resonance from 96 months leading to 36 months lagging causing a sine-shaped correlation variation with a strong positive SSTA from 87 to 50 months leading and a strong negative one from 20 months leading to 24 months lagging. (3) The same is true for the Weddell Sea ice and SSTA of the central-eastern equatorial Pacific but with a common period of quasi-5 years. ENSO events have a good correlation with sea ice in the eastern Antarctic in their later stage. The feedback of sea ice to SSTA in the western equatorial Pacific is also significant with a quasi-5 year period, but it is very weak to SSTA of the central-eastern equatorial Pacific. SST of the central equatorial Pacific has a quasi-contemporary oscillation relationship with Ross Sea ice and a 1.5 years lag oscillation relationship with Weddell Sea ice. We call this oscillation relationship between Antarctic sea ice and ENSO events, the Southern Oceanic Oscillation (SOO). |
