| Abstract: | The anomalous change of two polar sea ice and tropical ocean SST is a very important index for global climate monitoring and prediction. In this paper, wave resonance principle is used to calculate month by month running crosscouple correlation coefficient time series between sea ices in different sea areas of the two poles, as well as between themand five elements of El Nino event, to analyze their variation features. and to find out their resonance periods. The reso nance period of two waves is just the strongest interaction period.borne results are as follows: 1. The Arctic sea ice to the Pacific-side (NP11) and Atlantic-side (NP12 ) shows a mu tual strong positive-negative feedback impact with the Antarctic Ross Sea ice (SP12) in equal intensity. 2. Both NP11 andNP12 give a strong positive and negative feedback to the Antarctic Wedded Sea ice (SP13) while it is rather weak in con verse status. It means that the Arctic sea ice plays a leading and controlling role on the Wedded Sea ice. 3. SST of Nino4 area in the central equatorial Pacific has a best resonance period with SP12 in a cycle period of 132 months. It closely re lates to quasi-11-year oscillation period of both. SST of Nino 4 area also has a resonance period with SP13 in a cycle of 61months. There also exist strong interaction periods between the Antarctic sea ice and other elements of El Nino event butweaker than SST of Nino 4 area. |
