Summary: Blowing snow is a major weather phenomenon on the northwest Greenland Ice Cap. It occurs most often in winter and is at a minimum during the months of June, July, and August. Blowing snow is most commonly associated with winds of more than 20 knots; however, blowing snow occurs about 30% of the time when wind velocities are between 15-19 knots. Very little blowing snow occurs at wind velocities of less than 15 knots. During periods of blowing snow, visibility is usually greater than 1 mile when wind speeds are less than 20 knots and decreases to less than 1 mile when wind velocities exceed 20 knots. Blowing snow occurs most frequently during periods when air temperatures are between 10 to 14°F and -11 to -25°F at Site 1 and between -1 to -20°F and -41 to -45°F at Site 2. Periods of continuous blowing snow are usually less than 24 hr in duration and almost half of all such periods are less than 6 hr in duration.
