This paper investigates the relationship between high latitude upper mesospheric winds and the state of the stratospheric polar vortex in the absence of major sudden stratospheric warmings. A ground based Michelson Inter- ferometer stationed at Resolute Bay (74 43 0 N, 94 58 0 W) in the Canadian High Arctic is used to measure mesopause re- gion neutral winds using the hydroxyl (OH) Meinel-band air- glow emission (central altitude of 85 km). These observed winds are compared to analysis winds in the upper strato- sphere during November and December of 1995 and 1996; years characterized as cold, stable polar vortex periods. Cor- relation of mesopause wind speeds with those from the up- per stratosphere is found to be significant for the 1996 season when the polar vortex is subtly displaced off its initial loca- tion by a strong Aleutian High. These mesopause winds are observed to lead stratospheric winds by approximately two days with increasing (decreasing) mesospheric winds predic- tive of decreasing (increasing) stratospheric winds. No statis- tically significant correlations are found for the 1995 season when there is no such displacement of the polar vortex.
