Using Fabry-Perot interferometers (FPI) at five mid-latitude stations (Boulder, Palmer, Millstone Hill, Mt. John, and Kelan) in both hemispheres, we examine the inter-hemispheric and seasonal variations of mid-latitude thermospheric dynamics.

Periodic oscillations associated with Alfven waves with periods ranging from several tens of minutes to several hours are commonly seen in the solar wind.

In this work, Kedeng Zhang, Wenbin Wang and others, investigate the longitudinal patterns of thermospheric zonal winds (~400 km) and their seasonal and solar activity dependence.

The semidiurnal lunar and solar tides obtained from meteor radar measurements spanning from 2009 until 2013 observed at Davis (69°S) and Rio Grande (54°S) are presented and compared to the northern hemisphere at Andenes (69°N) and Juliusruh (54°N).
