Orographic gravity waves have a similar range of vertical and horizontal wavelengths to that of non-orographic waves (e.g. Whiteway and Duck, 1999), and are thus also often poorly resolved by GCMs. crysis widescreen fixWebbA strong signal of the two-day wave is diagnosed in a middle atmosphere GCM, with characteristics very similar to those of the observed two-day wave. It results from an instability, but its global structure shows similarities to a Rossby-gravity planetary normal mode.
