The article highlights the changes in atmospheric circulation in Antarctica in 2013. Topics discussed include the short-lived anomalous atmospheric circulation patterns across the continent, the negative surface pressure and geopotential height anomalies over the polar cap, and the stronger and opposite-sign circulation pattern that emerged in late winter and spring.

The article reports on the extent, concentration and duration of the Antarctic sea ice in 2013. Topics discussed include the positive trend in annual sea ice extent, the negative pressure anomalies across the continent, and the positive pressure anomalies at midlatitudes in January to May. The reduced circumpolar wind strength in August and September is mentioned.

The article focuses on the atmospheric circulation across Antarctica as of 2015. Topics discussed include the trends of the continent's atmospheric anomalies mentioning surface temperatures and pressure, its large-scale circulation considering factors such as geopotential height and surface pressure anomalies, and the observation on the zonal wind and geopotential height anomalies throughout the continent's troposphere and stratosphere.
