Abstract: EOF and power spectral analysis show that the interannual variability of the time coefficients of the second and third eigenvectyr of the Arctic sea ice cover in region Ⅰ has a period of approximately 40 months. At this frequency band EU and EA teleconnection patterns can be excited by the thermal forcing of the variation of the sea ice cover. By comparison it is confirmed that the influence of the Arctic sea ice cover on the midlatitude general circulation in Northern winter bears some analogue to one of the SST over the central-eastern equatorial Pacific. They are the important factors to induce the short term climatic change.
