Dynamics of the Antarctic and Arctic mesosphere and lower thermosphere – Part 1: Mean winds
the Antarctic and Arctic mesosphere lower thermosphere Mean winds
2010/11/29
Zonal and meridional winds have been measured in the upper mesosphere and lower thermosphere at polar latitudes using two ground-based meteor radars. One radar is located at Rothera (68° S, 68° W) in ...
Study on the impact of sudden stratosphere warming in the upper mesosphere-lower thermosphere regions using satellite and HF radar measurements
sudden stratosphere warming the upper mesosphere-lower thermosphere regions satellite and HF radar measurements
2010/8/12
The occurrence of a sudden stratospheric warming (SSW) excites disturbances in the mesosphere-lower thermospheric (MLT) wind and temperature. Here, we have examined the high frequency (HF) radar wind ...
The 16-day wave in the Arctic and Antarctic mesosphere and lower thermosphere
16-day wave Arctic and Antarctic mesosphere lower thermosphere
2010/2/21
The 16-day planetary wave in the polar mesosphere and lower thermosphere has been investigated using meteor radars at Esrange (68° N, 21° E) in the Arctic and Rothera (68° S, 68° W) in the Antarctic. ...
The two-day wave in the Antarctic and Arctic mesosphere and lower thermosphere
two-day wave Antarctic Arctic mesosphere lower thermosphere
2009/9/11
There have been comparatively few studies reported of the 2-day planetary wave in the middle atmosphere at polar latitudes. Here we report on a study made using high-latitude meteor radars at Rothera ...
Observations of lunar tides in the mesosphere and lower thermosphere at Arctic and middle latitudes
lunar tides mesosphere lower thermosphere Arctic middle latitudes
2009/1/15
Meteor radars have been used to measure the horizontal winds in the mesosphere and lower thermosphere over Castle Eaton (52° N) in the UK and over Esrange (68° N) in Arctic Sweden. We consider a 16-ye...
The wintertime two-day wave in the polar stratosphere, mesosphere and lower thermosphere
wintertime two-day wave polar stratosphere mesosphere lower thermosphere
2008/10/29
Recent observations of the polar mesosphere have revealed that waves with periods near two days reach significant amplitudes in both summer and winter. This is in striking contrast to mid-latitude obs...
Remote sensing lower thermosphere wind profiles using non-specular meteor echoes

This article describes a new method of measuring wind
velocity profiles between 93 km and 110 km altitude by
tracking non-specular meteor echoes as neutral winds
