Antarctica Jet Stream
The jet stream has high turbulence in animation (click here). The arrival of heat transfer is evident throughout the air column in Antarctica with most of it's impact at surface winds where most of the energy is subliming ice and causing percipitation.

Antarctica Dew Point (in animation click here)
A quick review of 'dew point' to understand the brevity of this satellite. The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. If the relative humidity is 100%, the dew point is equal to the current temperature. Given a constant dew point, an increase in temperature will lead to a decrease in relative humidity. It is for this reason that equatorial climates can have low relative humidity, yet still feel humid.
Okay, if noted the 'relative humidity' in the satellite below is high. Therefore, the 'dew point' in the satellite above will reflect the 'current air temperature.' In animation the 'average' dew point is occuring at between 0 Fahrenheit to 20 Fahrenheit. 32 degrees is freezing and while this dew point is occuring at 0 to 20 F, that is still very, very warm for an ice continent still in the depths of winter. Hence, considering the high relative humidity and the blowing snows across the continent there is a large degradation of the ice into percipitation at rather high temperatures for this continent. The arriving heat transfer vortices are the reason.

Antarctica Humidity Satellite (in animation, click here)
There are high levels of humidity over the entire continent on animation of the satellite. What does everyone know is necessary for heat transfer? Humidity. Where does that humidity come from on an ice continent? Sublimation of the ice.

Visibility satellite on animation (click here)
The visibility is very low due to blowing snow over most of the continent on animation of this satellite. The exception is southeast area.

Surface Wind Satellite in animation (click here)
The surface winds reach over 18 km/hr (40 mph) in the northern areas.

Antarctica Windchill Satellite in animation (click here)
It obvious the wind is contributing to the movement of cold temperatures from East to West Antarctica.

South Pole Satellite
Lots of heat transfer arriving to Antarctica. Surface winds are causing most of the continent to have cold distribution that is unusual. Blowing snow is the weather conditions of the day where reported.
