Gravity waves can affect an existing cloud pattern in several ways as they propagate through.....
Results from several studies (Zhang and Fritsch, 1988, Schneider, 1990 and Powers and Reid, 1993) indicated that convection was essential for the development, maintenance and amplification of gravity waves.
Results in a separate study (Bosart and Seimon, 1988) of a wave depression forming behind a squall line in an area of strong static stability, concluded that gravity waves shared similarities with wake lows associated with convective systems.
Interactions between Gravity Waves and Convection
Wave CISK Theory - Organized convection is forced by convergence associated with a gravity wave, while latent heat release within the convection provides a source of wave energy. Convection amplifies the wave trough by compensating subsidence and enhances the wave ridge by evaporative cooling of precipitation.
Wave CISK theory also states that the strongest convective vertical
motions must also exist at the wave critical level instead of midway through
the stable layer so the gravity wave and the convective system move in
