HAO Research Highlights

Dependence of lunar tide image
April 5, 2018

The lower atmospheric forcing effects on the ionosphere are particularly evident during extreme meteorological events known as sudden stratospheric warmings (SSWs).

Gravity wave drag anomaly
March 16, 2018

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.

Comparison of measured to modeled global total electron content
March 13, 2018

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.

Longitudinal structures of zonal winds
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.

Meridional wind variability
February 28, 2018

For the first time, a new module enables Jing Liu and others to investigate the intimate coupling between polar turbulence electron heating and thermosphere disturbances in the context of a first principle, self-consistent model.
