Reduction of the Entrainment Velocity by Cloud Droplet Sedimentation in Stratocumulus
Publisher: American Meteorological Society
Abstract: AbstractThe effect of sedimentation on stratocumulus entrainment is investigated using direct numerical simulations of a cloud-top mixing layer driven by radiative and evaporative cooling. The simulations focus on the meter ...
Direct Numerical Simulations of a Smoke Cloud–Top Mixing Layer as a Model for Stratocumuli
Publisher: American Meteorological Society
Abstract: radiatively driven cloud-top mixing layer is investigated using direct numerical simulations. This configuration mimics the mixing process across the inversion that bounds the stratocumulus-topped boundary layer. The main ...
Mixing Driven by Radiative and Evaporative Cooling at the Stratocumulus Top
Publisher: American Meteorological Society
Abstract: he stratocumulus-top mixing process is investigated using direct numerical simulations of a shear-free cloud-top mixing layer driven by evaporative and radiative cooling. An extension of previous linear formulations allows ...
Scaling Laws for the Heterogeneously Heated Free Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: he heterogeneously heated free convective boundary layer (CBL) is investigated by means of dimensional analysis and results from large-eddy simulations (LES) and direct numerical simulations (DNS). The investigated physical ...
