Concurrent Wave Activity in the Polar Mesosphere-Ionosphere Region
Abstract
Airglow observations from the winter polar mesosphere and ionosphere over Eureka, Nanavut (80 degrees N, 86 degrees W) through the past solar cycle have shown occasional coupling of mesospheric gravity and tidal waves with the F-region (as seen from [O] 630 nm airglow emissions). In addition to what appear to be tidal harmonics, there are observations of shorter duration gravity waves of 15-30 minute periods. The characteristics of these waves will be illustrated and coupling processes will be discussed.
