Experimental evidence for solar cycle and long-term change in the low-latitude MLT region

Journal of Atmospheric and Solar-Terrestrial Physics, 2005
Abstract There is a great deal of interest in long-term change in the upper atmosphere and its possible relationship with human activities, but it is clear that we do not yet have a consistent picture of solar cycle and long-term trends in the MLT region.

Periodic auroral forms and geomagnetic field oscillations in the 1400 MLT region

Journal of Geophysical Research: Space Physics, 1990
The UV images obtained with the Viking satellite often show bright features which resemble “beads” or “pearls” aligned in the east–west direction between noon and 1800 MLT (Lui et al., 1989). Viking acquired a series of 25 UV images during a 28‐min period on July 29, 1986, which showed a distinctive series of periodic bright features in this region ...

Planetary wave induced wind and airglow oscillations in the middle latitude MLT region

Journal of Atmospheric and Solar-Terrestrial Physics, 2013
Abstract Upper mesosphere airglow emissions and temperature observed at Rikubetsu (43.5°N,143.8°E) and mesospheric winds observed at Wakkanai (45.4°N,141.8°E), Japan, from January to December 2005 were used to analyze periodic oscillations of 2–16 days.

Study of the Quasi 10‐Day Waves in the MLT Region During the 2018 February SSW by a Meteor Radar Chain

Journal of Geophysical Research: Space Physics, 2021
We present a study of the quasi 10‐day waves (Q10DWs) in the mesosphere and lower thermosphere (MLT) during a sudden stratospheric warming (SSW) event in February 2018 based on three meteor radars located at Mohe (MH, 53.5°N, 122.3°E), Beijing (BJ, 40.3 ...

Observations of a Strong Intraseasonal Oscillation in the MLT Region During the 2015/2016 Winter Over Mohe, China

Journal of Geophysical Research: Space Physics, 2022
Using meteor radar measurements at Mohe (MH, 53.5°N, 122.3°E) and the reanalysis data from 2011 to 2020, the characteristics of intraseasonal oscillations (ISOs) in the mesosphere and lower thermosphere (MLT) region over MH are investigated for the first

Study of a Quasi‐27‐Day Wave in the MLT Region During Recurrent Geomagnetic Storms in Autumn 2018

Journal of Geophysical Research: Space Physics, 2021
A quasi‐27‐day wave (Q27DW) caused by the rotational period of solar radiation is commonly observed in the atmospheric dynamics. In the present study, we report an enhancement of a Q27DW during recurrent geomagnetic storms in the autumn of 2018 based on ...
