| Zusammenfassung |
| In summer 2010 Russia and Japan experienced an extreme heatwave. Further, reanalysis data
show that the Barents Sea was about 3°C warmer than climatology and that the sea-ice cover
was reduced in spring/summer in that region. In this study we link the Barents Sea anomaly
and the temperature variations over Europe and Asia. We found that a crucial element is the
stability of the lower atmosphere over the Barents Sea region. If a stable lower atmosphere
will be destabilized through the anomaly, the temperatures in Russia and eastern Asia
decrease. If the anomaly occurs during a time when the lower atmosphere is unstable, Russia
and eastern Asia experience warm temperatures. Additionally, we have investigated the
relative importance of a tropical SST anomaly in relation with a polar SST anomaly. |
