Summary: | During 2011, zonally-averaged Antarctic sea iceextent was characterized by three broad phases thatwere closely associated with the changes in largescalepatterns of atmospheric circulation describedin section 6b. From near-average levels at the beginning of theyear (compared to the 19812010 mean), the zonallyaveragedsea ice extent tracked at 12 standard deviationsbelow the long-term mean from mid-Januarythrough mid-May (Fig. 6.8a) - including some brieftimes when it dipped below the 30-year record. |
