Multisensor profiling of a concentric gravity wave event propagating from the troposphere to the ionosphere (2015, background): “However, dissipation properties of GWs for a typical temperature profile of the atmosphere for the date and time shown here suggest that these small-scale waves will tend to dissipate much lower in the atmosphere and will not able to penetrate the ionosphere [Vadas, 2007].”
Sources of the traveling ionospheric disturbances observed by the ionospheric TIDDBIT sounder near Wallops Island on 30 October 2007 (2010, methodology): “spectra from plumes and clusters are shown by Vadas et al. [2009a]. Next, we position each GW spectrum at the location of the convective object (at 0432 UT and z = ztrop), and ray trace the GWs into the stratosphere, mesosphere, and thermosphere.”
Unexpected connections between the stratosphere and ionosphere (2010, background): “Recent studies explored such connections through tidal modes originating from tropospheric heating processes [Hagan et al., 2009] or gravity waves excited by topography, convection or wind shear near Earth’s surface [ Vadas, 2007 ].”
Generation of large-scale gravity waves and neutral winds in the thermosphere from the dissipation of convectively generated gravity waves (2009, neutral): “…approximately exponentially with altitude, equation (9) shows that GWs with the largest lz and wIr survive to the highest altitudes before dissipating, although the dependence is stronger for lz than for wIr [Vadas, 2007 (hereinafter V2007), and references therein; Miyoshi and Fujiwara, 2008].”
Variability and predictability of the space environment as related to lower atmosphere forcing (2016, background): “GWs, especially the high-frequency components and secondary GWs from the dissipation of primary waves, can LIU SPACE WEATHER AND TERRESTRIAL WEATHER 644 penetrate into the thermosphere and cause thermospheric and ionospheric disturbances [e.g., Hines, 1960; Vadas and Fritts, 2001; Vadas, 2007].”
