Parameterization of the effects of vertically propagating gravity waves for thermosphere general circulation models: Sensitivity study (2008, background): “Most of these schemes either do not treat GW propagation into the thermosphere, or apply ad hoc nonphysical techniques in order to represent wave dissipation above the MLT.”
Gravity wave penetration into the thermosphere: sensitivity to solar cycle variations and mean winds (2008, background): “These “secondary” GWs often occur on larger spatial scales than the GWs accounting for their generation (Vadas and Fritts, 2001, 2002; Vadas et al., 2003).”
A global view of stratospheric gravity wave hotspots located with Atmospheric Infrared Sounder observations (2012, background): “Other sources that are important, at least for certain meteorological conditions, are wind shear, adjustment of unbalanced flows near jet streams and frontal systems, body forcing accompanying localized wave dissipation, and wave-wave interaction [Fritts and Alexander, 2003; Vadas et al., 2003; Wu a”
Thermospheric responses to gravity waves arising from mesoscale convective complexes (2004, methodology): “Our formulation is based on that employed previously by Vadas and Fritts (2001, 2002) and Vadas et al. (2003) to describe the mean and gravity wave S.L.”
Generation of large-scale gravity waves and neutral winds in the thermosphere from the dissipation of convectively generated gravity waves (2009, unknown): “[5] It is well known that localized neutral winds and secondary GWs are generated from horizontal body forces in nonviscous fluids [Zhu and Holton, 1987; Fritts and Luo, 1992; Luo and Fritts, 1993; Vadas and Fritts, 2001 (hereinafter VF2001); Vadas et al., 2003 (hereinafter V2003)].”
Mean and variable forcing of the middle atmosphere by gravity waves (2006, background): “Instability dynamics also impose both mean and spatially and temporally localized flux divergence that forces the zonal mean circulation and excites additional GWs at higher altitudes (Fritts et al., 2003; Vadas and Fritts, 2001; Vadas et al., 2003).”
Internal wave coupling processes in Earth's atmosphere (2014, unknown): “Such mechanism of secondary excitation has been extensively studied (e.g., Vadas et al., 2003; Chun and Kim, 2008), and found to be a likely source of harmonics that can effectively propagate into the upper thermosphere (Vadas and Liu, 2011).”
Sources of the traveling ionospheric disturbances observed by the ionospheric TIDDBIT sounder near Wallops Island on 30 October 2007 (2010, result): “... downward‐propagating secondary GWs and large‐scale TIDs (LSTIDs) with lH ’ 2100 km, cH ’ 500 m/s, and periods of tr ’ 80 min which propagate away from the body force as concentric, anti‐symmetric rings to z ^ 420 km. This result shared many similarities with the mean wind and secondary GWs excit”
