Parameterization of Entrainment Rate for Cumulus Clouds with WRF Simulation

Atmosphere, 2023
By using Weather Research and Forecasting Model (WRF) to simulate a southwest vortex precipitation process, this work studies the correlations between entrainment rate (λ) and dynamical parameters in the cloud and further fit λ. We relate the probability

Influences of an entrainment–mixing parameterization on numerical simulations of cumulus and stratocumulus clouds [PDF]

Atmospheric Chemistry and Physics, 2022
Different entrainment–mixing processes can occur in clouds; however, a homogeneous mixing mechanism is often implicitly assumed in most commonly used microphysics schemes.

Parameterizations for convective transport in various cloud-topped boundary layers [PDF]

Atmospheric Chemistry and Physics, 2015
We investigate the representation of convective transport of atmospheric compounds by boundary layer clouds. We focus on three key parameterizations that, when combined, express this transport: the area fraction of transporting clouds, the upward

Impact of Interactive Vertical Overlap of Cumulus and Stratus on Global Aerosol, Precipitation, and Radiation Processes in the Seoul National University Atmosphere Model Version 0 With a Unified Convection Scheme (SAM0‐UNICON)

Journal of Advances in Modeling Earth Systems, 2019
The previously proposed parameterization for the integrated vertical overlap of cumulus and stratus is generalized to handle both conventional exponential‐random stratus overlap and nonconventional (i.e., other than exponential‐random) cumulus overlap in
