ARCTIC Cold Air Drainage West of Fort Nelson, British Columbia

ABSTRACT. In the early mornings of 7,22 and 23 January 1982, intense cold air drainage was observed in the valleys on the eastern slopes of the Rocky Mountains west of Fort Nelson, British Columbia. Temperature differences of 31°C were noted, the coldest temperature recorded being-71°C (a new North...
