Extreme responses of a coupled scalar-particle system during turbulent mixing

Extreme responses of a droplet ensemble during an entrainment and mixing process as present at the edge of a cloud are investigated by means of three-dimensional direct numerical simulations in the Euler–Lagrangian framework. We find that the Damköhler number Da, a dimensionless parameter which relates…

Entrainment and mixing at the interface of shallow cumulus clouds: results from a combination of observations and simulations

This study combines observations, large-eddy simulations (LES), and direct numerical simulations (DNS) in order to analyze entrainment and mixing in shallow cumulus clouds at all relevant spatial scales and, additionally, to verify the results by the multiple methods used. The observations are based…
