Any turbulence is primarily occurring from East Antarctica toward West Antarctica. But, West Antarctica is primarily calm. That was reflected in some reporting stations as well.

The vortices have retreated back to latitudes 60 to 45 degrees South. South of Australia there is some heat movement to 75 degrees South. So, this week the troposphere is cooler but the oceans are warmer. When one considers the calories of heat transfer that occurs to result in this type of change it is easier to realize how the oceans are heating even though they are so vast.
