Abstract

We report on stratospheric and mesospheric water vapor (H₂O) observations obtained by the Millimeter wave Atmospheric Sounder (MAS) in the Arctic spring of 1992. In the lower stratosphere, the observations show enhanced H₂O inside the vortex between 450 K and 625 K, in agreement with other H₂O observations. In the upper stratosphere and lower mesosphere, at potential temperatures between 1850 K and 2200 K, we find regions of depressed H₂O volume mixing ratio coincident with remnants of high potential vorticity. The depressed mesospheric H₂O, as well as the enhanced lower stratospheric H₂O, are consistent with wintertime descent. It also suggests effective containment of air up into the lower mesosphere.
