A Mesoscale Gravity Wave Event Observed during CCOPE. Part III: Wave Environment and Probable Source Mechanisms

Sudden changes in aerosol and gas concentrations in the central Arctic marine boundary layer: Causes and consequences

“…They state that mesoscale gravity waves are increasingly recognized for their ability to modulate cloud and precipitation fields, to produce and interact with deep convection and turbulence and to transport energy horizontally. Uccellini and Koch [1987] and Koch and Dorian [1988] have reviewed the synoptic setting and possible energy sources for these waves. They suggest that generation occurs through a shedding of a gravity wave-inertia wave packet in association with a geostrophic adjustment process, a jet stream approaching a stationary ridge in the 300 hPa height field being a favored location.…”

Sensitivity of Mesoscale Gravity Waves to the Baroclinicity of Jet-Front Systems

“…They are closely associated with a wide variety of atmospheric processes， ranging from microscale to synoptic scale dynamical phenomena，such as clear air turbulence, convection and baroclinic waves. Generally, gravity waves (GWs) can be generated by topography, frontogenesis, convection, shear instability, geostrophic adjustment and wave-wave interactions (Koch and Dorian 1988;Fritts and Alexander 2003).…”

Application of the Lighthill–Ford Theory of Spontaneous Imbalance to Clear-Air Turbulence Forecasting

“…CAT diagnostics based on the advective Rossby number, such as the inertial-advective wind (Knox 2001), and the Lagrangian Rossby number (van Tuyl and Young 1982;Koch and Dorian 1988) have been used with some success in CAT forecasting. Interestingly, the leading-order term of our scale analysis results from this second vector term on the RHS of (4).…”
