The air flowing down on the ice shelf is almost 20 K warmer than the surrounding air (220 K). The temperature on the mainland and the ice shelf is about the same.
See also the very sharp boundary between the Ice shelf and the sea ice. The temperature difference is again almost 20 K (235 K on the ice shelf edge and 255 K over the sea ice).
