We present new results of the effect of atmospheric stochastic backscatter injection in the Australian Community Climate and Earth System Simulator (ACCESS) coupled model at high resolution. We demonstrate improvements in the turbulent kinetic energy spectrum in the inertial wavenumber range of the atmosphere and show the impact on the large-scale atmospheric flow. This is the so-called "tail wagging the dog" effect, where injecting stochastic backscatter at high wavenumbers results in lower kinetic energy at low wavenumbers. Previous studies have shown that such improvements in the turbulent kinetic energy spectrum in the inertial range result in more accurate modelling of large-scale phenomena.
