| description | <p>In austral spring 2016 the Antarctic region experienced anomalous sea ice
retreat in all sectors, with sea ice extent in October and November 2016
being the lowest in the Southern Hemisphere over the observational period
(1979–present). The extreme sea ice retreat was accompanied by widespread
warming along the coastal areas as well as in the interior of the Antarctic
continent. This exceptional event occurred along with a strong negative phase
of the Southern Annular Mode (SAM) and the moistest and warmest spring on
record, over large areas covering the Indian Ocean, the Ross Sea and the
Weddell Sea. In October 2016, the positive anomalies of the totally
integrated water vapor (IWV) and 2 m air temperature (T2m) over the Indian
Ocean, western Pacific, Bellingshausen Sea and southern part of Ross Sea were
unprecedented in the last 39 years. In October and November 2016, when the
largest magnitude of negative daily sea ice concentration anomalies was
observed, repeated episodes of poleward advection of warm and moist air took
place. These results suggest the importance of moist and warm air intrusions
into the Antarctic region as one of the main contributors to this exceptional
sea ice retreat event.</p> |
