Immediate report on the Victoria University of Wellington Antarctic Expedition 1959-60: VUWAE 3
Constant winds, relatively high temperatures and low precipitation are characteristic of the dry-valleys.
The wind at the main bases averaged 8.4 miles per hour. The highest wind-run over a 24 hour period was 24 miles per hour. The highest gust was not recorded, but it probably exceeded 60 Knots: The hand aremometer, capable of recording winds up to this velocity blew to pieces on January 24.page 12
In the wright Valley, which is long and narrow and confined for the most part between 5000 feet walls, the winds at the western end blew either directly up or down valley. They tended to follow a rhythm with easterlies blowing during the afternoon and westerlies during the morning. Easterly winds prevailed in the eastern part of the valley.
Wind in the Victoria Valley system immediately to the north did not follow this pattern; it was invariably from the east throughout the length of the area.
That the easterly wind is predomenant in the Lake Vida area can he deduced from the conformation of the barchan sand dunes to the north of the lake.
The heaviest winds at Lake Vashka came from the south. It must he understood however that the general picture of wind flow in this mountainous region is governed largely by orographical features.
