Kara-Siberian sea ice anomaly and its impact on the atmosphere

Abstract

The behavior of the autumn and winter weather pattern over Europe and Eurasia was investigated during two periods of high and low ice concentration in September over the Kara-Siberian sea. A statistically significant anomalous energy flux from the east Siberian sea to the atmosphere was detected during October of low ice years. Furthermore, an anomalous behavior in the atmospheric circulation was detected during the October of the LIYs. Additionally, statistically significant positive anomaly was observed over northern Europe and central Eurasia during January and February of the years with high ice concentration at the Kara-Siberian sea.
