| Zusammenfassung |
The spring of 1997 has represented a stable
period of operation for the joint University of Tromsø / University of
Saskatchewan MF radar, being between refurbishment and upgrades. We examine the
horizontal winds from the February to June inclusive and also include estimates
of energy dissipation rates derived from signal fading times and presented as
upper limits on the turbulent energy dissipation rate, ε.
Here we address the periodicity in the dynamics of the upper mesosphere for time
scales from hours to one month. Thus, we are able to examine the changes in the
spectral signature of the mesospheric dynamics during the transition from winter
to summer states.
Key words. Meteorology and atmospheric dynamics (middle
atmosphere dynamics; turbulence; waves and tides). |
