Abstract: Turbulence is key for the evolution of planetary boundary layers. There are important regimes, however, in which the effect of turbulence is unclear, particularly near the surface and at the boundary-layer top, where metre and submetre scales become important. Characterising the interaction of turbulence and density stratification, radiative transfer and cloud physics at those small scales remains challenging for measurements and for numerical models that parametrise turbulence. Direct numerical simulations – whereby the Navier-Stokes equations describing the fluid motion are solved directly, without a turbulence parametrisation – are providing further insight into those interactions. In this paper, we summarise recent results that illustrate this approach, and we indicate remaining challenges that could be solved in the near future.
