Antarctica Surface Wind Image (click here for 24 hour loop)
The wind is primarily the same in that WAIS winds are primarily offshore, hence removing coldness. The winds off the top of the Blue Ice move primarily toward East Antarctica. The reason may be related to the fact the lower altitude winds are primarily onshore, hence bringing the hottest temperatures to the ice continent. It would make sense then the onshore warm winds would be more of an updraft against the Blue Ice as less dense air would rise and/or create percipitation. With an updraft over the lower altitudes of Antarctica it could create a subsidence of denser air off the Blue Ice. A subsidence of this type would be marked by percipitation and/or sublimation of the ice. And indeed at Casey and Davis in East Antarctica the 'conditions' are partly cloudy with pressure falling at Casey.

Antarctica Jet Stream Image (click here for animation from Sunday, March 22 - 24)
In animation, the direct center of the vortex is noted to be disturbed from a heat transfer system of high tropospheric origins. The equinox in 2009 was March 20th at 11:44 UTC.

This station is not reporting! - this station has been stating this for nearly a month or more, however, the facts regarding the conditions at Vostok have changed during that time. So, obviously, the station is having issues even if it is in error of reporting it is not reporting.
