Sources, sinks and propagation characteristics of the quasi 6-day wave and its impact on the residual mean circulation

Amplitudes of the Q6DW as a function of latitude and time
Saturday, August 25, 2018

This study, by Pedatella and others, employs a troposphere to lower thermosphere reanalysis dataset generated by the Whole Atmosphere Community Climate Model with data assimilation provided by the Data Assimilation Research Testbed (WACCM+DART).

The influence of internal atmospheric variability on the ionosphere response to a geomagnetic storm

Change in WACCMX simulated total electron content (TEC) during a geomagnetic

Nicholas Pedatella notes that geomagnetic storms are an important driver of variability in Earth’s ionosphere, and can have significant societal impacts through the ionosphere’s impact on communications and navigation systems (e.g., GPS).

Analysis and Hindcast Experiments of the 2009 Sudden Stratospheric Warming in WACCMX+DART

Total electron content (TEC)
Thursday, December 7, 2017

Plain Language Summary or Abstract: Whole atmosphere models offer the opportunity to improve specification and forecasting of the upper atmosphere through incorporating the effects of forcing from both the lower atmosphere as well as the Sun.

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).
