| Zusammenfassung |
Analyses of time-spatial
variations of critical plasma frequency foF2 during the summer of 1998
reveal the existence of an oscillation activity with attributes of a 6-day
westward propagating wave. This event manifests itself as a global scale wave
in the foF2 of the Northern Hemisphere, having a zonal wave number 2.
This event coincides with a 6-day oscillation activity in the meridional
neutral winds of the mesosphere/lower thermosphere (MLT). The oscillation in
neutral winds seems to be linked to the 6–7-day global scale unstable mode
westward propagating wave number 1 in the MLT. The forcing mechanisms of the
6-day wave event in the ionosphere from the wave activity in the MLT are
discussed.
