The Mid-latitude Thermospheric Dynamics from An Inter-hemispheric Prospective

Graph depicting Meridional and Zonal Winds
Monday, January 28, 2019

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.

Temporal Variation of Solar Wind in Controlling Solar Wind‐Magnetosphere‐Ionosphere Energy Budget

Cross-correlation between Joule heating and the Epsilon function.

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

The longitudinal variations of upper thermospheric zonal winds observed by the CHAMP satellite at low and mid-latitudes

Longitudinal structures of zonal winds
Thursday, March 1, 2018

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.

Climatology of semidiurnal lunar and solar tides at mid and high latitudes: comparison between hemispheres

Mean zonal wind
Friday, July 7, 2017

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).
