The large high near the pole had moved to a position northwest of SHEBA ship. The ship was under northeasterly winds with a few low clouds. Barrow appears clear on the visible satellite image, but the 3.7 micron image indicates a possible optically thin low stratus cloud over the coast extending north over the ocean.
The trajectories to SHEBA ship show all air coming from near the pole. The higher level trajectories, 3, 6, and 9 km, trace back into Greenland. Winds at 9 km were especially strong since the trajectory reached Greenland in just under two days. The lower levels indicate much lighter winds.
The trajectories to Barrow show light winds in the Beaufort Sea. The low level trajectories, surface to 3.0 km, all trace northeast into the Beaufort Sea. The 6 km trajectory traces in the opposite direction - south into central Alaska. However, winds were light at 6 km as indicated by the short length of this trajectory. The high level 9 km trajectory also traces south across Alaska to Anchorage in two days and then curves west across the Bering Sea into Siberia.
