Antarctica
Vortices are at every corner of Antartica and in the wind map below it is obvious over WAIS (West Antarctica Ice Sheet) as the wind is primarily offshore as colder heavier air from the top of the Blue Ice falls to the lower altitudes of WAIS displacing the lighter warmer air. Noted in the satellite picture above, the Weddell Sea, east of the Peninsula is receiving a vortex directly.

The vortices offshore are obvious. In animation there is a lot of distrubance of the Jet Stream as the heat transfer is occuring at higher altitudes. The vortices are affecting the Jet Stream at most altitudes as noted at 6:00 AM with a profound and equal distrubance wave at 12 o'clock.
It is still winter in Antarctica and already on the Peninsula the temperatures are nearly above zero and rising.
