Winds of Antarctica
At 11:00 is the movement of frigid air from the continent. At 3 to 4:00 is the arrival of air from the Australian Pacific. The vortex from the Mid-Pacific east of the Indonesian Islands is approaching west of the peninsula. It will arrive within a day or two and cause high temperatures in the area of the ice sheets.
Still notable and larger in area is the southwest stagnation of wind over WAIS (the big blue spot). There is a 'settling' of increased temperatures. Overall the continent reporting stations are below zero C, but, the temperatures are lower than they have been. Vostok is down in the negative fifties.
