A Source of Clear-Air Turbulence? Tracking Gravity Wave Formation in Inertially Unstable Regions

From Timothy Banyard (he/him), Postdoctoral Research Associate, University of Manchester

Abstract: We present results from several case studies exhibiting this behaviour, identifying the sources of the gravity waves observed in simulations. The characteristics of these waves will be compared to those in the idealised model simulations, and gravity-wave parameters will be calculated. Finally, we widen our analysis by examining the broader upstream pattern that contributes to the development of the initial inertial instabilities and explore the different regimes under which these phenomena occur.
