## Abstract

Atmospheric boundary layer turbulence in stably stratified conditions is characterised by an intermittent, unsteady behaviour. The intermittency can result from localised flow acceleration due to non-turbulent motions, which can exhibit structures such as ramp-cliff convective patterns, waves or microfronts. Based on a timeseries clustering method, we characterise interactions between scales of motion in a dataset of near-surface stable boundary layer turbulence. Individual flow structures are investigated in two weak-wind flow regimes exhibiting distinct scale interaction properties. The signature of flow structures differs despite comparable wind and stability properties.
