The high-resolution thermosphere-ionosphere-electrodynamics general circulation model (TIEGCM) was used to investigate the cause of F2-region electron density (Ne) responses to the Great American Solar Eclipse on 21 August 2017 at Millstone Hill (42.610N, 71.480W).
The lower atmospheric forcing effects on the ionosphere are particularly evident during extreme meteorological events known as sudden stratospheric warmings (SSWs).
Whole Atmosphere Community Climate Model (WACCM) simulations are used to investigate the short-term (30-day) temporal variability in the mid- and high-latitude Southern Hemisphere mesosphere.
Solomon & Qian show that solar minima are not all the same, and may have implications for understanding the Sun during the extended periods of very low activity known as “grand minima” that have sometimes occurred in the past, the best known of which was the Maunder Minimum during 1650–1700.
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.
