Conclusions
With the above analyses, we come to the followingg conclusions
-
(1)
Interannual variations of winter sea-ice extent in the Greenland, the Kara and the Barents Seas can induce the Northern Hemispheric atmospheric circulation anomalies, especially when winter atmosphere lags winter sea-ice by 3 a.
-
(2)
ENSO events happened when the variation velocities of winter sea-ice extent in the Greenland, the Kara and the Barents Seas reached an extreme value.
-
(3)
The third year before ENSO events happened, 62.5% ofthe variation velocities of winter sea-ice extent in the Greenland, the Kara and the Barents Seas reached a negative extreme value.
