“…Indeed, terrestrial observations have often provided the clues to their interpretation on Mars. Lee waves at small spatial scales and lower altitudes provided the first indications of GW influences [ Briggs and Leovy , 1974; Pirraglia , 1976; Briggs et al , 1979; Pettengill and Ford , 2000]. At higher altitudes, evidence for enhanced diffusion, mean temperatures far above radiative equilibrium at winter polar latitudes, and zonal jet closure provided evidence of likely GW momentum transport, possible additional turbulence transport, and a residual (meridional and vertical) circulation induced by GW instability and mean‐flow interactions [ Blamont and Chassefiere , 1993; Deming et al , 1986; Keating et al , 2002; Read and Lewis , 2004].…”
