Journal ArticleDOI
Planetary waves in coupling the lower and upper atmosphere
TL;DR: In this paper, a set of runs with a mechanistic Middle and Upper Atmosphere Model has been performed to investigate a possibility of the normal atmospheric modes (NM) forcing by stratospheric vacillations and to consider the propagation of different planetary waves up to the heights of the upper thermosphere.
Journal ArticleDOI
Planetary wave activity obtained from long-period (2-18 days) variations of mesopause region winds over Central Europe (52°N, 15°E)
TL;DR: In this paper, daily analyses of the zonal and meridional prevailing wind at the mesopause region around 95 km height are investigated with respect to long-period variations with periods ranging between 2 and 18 d that may with some restrictions be interpreted as planetary wave activity.
Journal ArticleDOI

TL;DR: The PSMOS Global-scale tidal variability experiment campaign of June 1-August 31, 1999, a network of radars made measurements of winds, waves and tides in the mesosphere/lower-thermosphere region over a wide range of latitudes as mentioned in this paper.
Journal ArticleDOI
Global-scale tidal structure in the mesosphere and lower thermosphere during the PSMOS campaign of June-August 1999 and comparisons with the global-scale wave model

Oleynikov,Dennis M. Riggin +27 more
TL;DR: In this article, the authors investigated the ability of the GSWM-00 to simulate the solar tides in the mesopause region (90-95 km) and found that it provides an increasingly reasonable estimate of most of the tidal characteristics in the MLT region.
Journal ArticleDOI
Climatology of the semidiurnal tide at 52–56°N from ground-based radar wind measurements 1985–1995

TL;DR: In this paper, the authors investigated the long-term wind measurements carried out at 6 northern midlatitude sites (Saskatoon, Sheffield, Juliusruh, Collm, Obninsk, Kazan) to establish a climatology of the semidiurnal tide in the mesopause region for the narrow latitudinal range between 52°N and 56°N.
