• Thermospheric responses to gravity waves arising from mesoscale convective complexes (2004, background): “The largest vertical wavelengths (and phase speeds) also are favored by deep convection (Salby and Garcia, 1987), and the most energetic waves are excited by the most intense convection having the strongest heating and the largest vertical motions (Piani et al., 2000; Lane et al., 2001).”
• Sources of the traveling ionospheric disturbances observed by the ionospheric TIDDBIT sounder near Wallops Island on 30 October 2007 (2010, background): “[7] Many non‐linear models [Piani et al., 2000; Horinouchi et al., 2002; Lane et al., 2001, 2003] and linear models [Stull, 1976; Salby and Garcia, 1987; Alexander et al., 1995; Walterscheid et al., 2001; Beres, 2004] of GW excitation from deep convection have been developed.”
• Concentric gravity waves in the mesosphere generated by deep convective plumes in the lower atmosphere near Fort Collins, Colorado (2009, background): “Additionally, concentric CGWs propagating through large-scale winds (such as the QBO) become anisotropic, resulting in only half of the rings being visible [Piani et al., 2000].”
• Generation of large-scale gravity waves and neutral winds in the thermosphere from the dissipation of convectively generated gravity waves (2009, background): “[8] Many nonlinear models of GW excitation from convection have been developed [Piani et al., 2000; Horinouchi et al., 2002; Lane et al., 2001, 2003].”
• Gravity wave penetration into the thermosphere: sensitivity to solar cycle variations and mean winds (2008, background): “…deep convection could penetrate to mesospheric and lower thermospheric (MLT) altitudes and have corresponding TI responses (Alexander et al., 1995; Piani et al., 2000; Lane et al., 2001; Lane and Clark, 2002; Horinouchi et al., 2002; Vadas and Fritts, 2004, 2006, hereafter VF06; Vadas, 2007,…”
• A Method of Specifying the Gravity Wave Spectrum above Convection Based on Latent Heating Properties and Background Wind (2004, methodology): “The model is a variant of the Durran and Klemp (1983) nonlinear, nonhydrostatic cloud-resolving model and is identical to that used in Piani et al. (2000).”
• An overview of the past, present and future of gravity‐wave drag parametrization for numerical climate and weather prediction models (2003, background): “However, recent cloud-resolving numerical modelling studies (e.g., Alexander et al., 1995; Piani et al., 2000; Lane et al., 2001) show more momentum flux contributed by waves propagating westward relative to the convective system.”
• Gravity wave dynamics and effects in the middle atmosphere (2003, background): “[41] For pure thermal forcing in the absence of strong shear the heating depth and the vertical wavelength of the gravity waves generated are surprisingly approximately equal [Alexander et al., 1995; Piani et al., 2000].”
• Mean and variable forcing of the middle atmosphere by gravity waves (2006, background): “These are (1) thermal forcing via latent heat release that excites vertical scales comparable to the forcing depth (Bergman and Salby, 1994; Alexander et al., 1995; Piani et al., 2000), (2) the ‘‘obstacle’’ or ‘‘transient mountain’’ effect in which wind shear at cloud top imposes relative motion ove”
• Impact of a Spectral Gravity Wave Parameterization on the Stratosphere in the Met Office Unified Model (2002, background): “As noted by Alexander and Rosenlof (1996), this is another reason why Rayleigh friction, which damps the winds everywhere, should be replaced by a more realistic parameterization.”
• GRACILE: a comprehensive climatology of atmospheric gravity wave parameters based on satellite limb soundings (2017, background): “…waves) (e.g., McFarlane, 1987; Lott and Miller, 1997), gravity waves excited by convection (e.g., Fovell et al., 1992; Pfister et al., 1993; Piani et al., 2000; Song and Chun, 2005), and gravity waves generated by source processes related to strong wind jets, for example the subtropical…”
