Marine stratocumulus aerosol-cloud relationships in the MASE-II experiment: Precipitation susceptibility in eastern Pacific marine stratocumulus [PDF]

, 2009
Observational data on aerosol-cloud-drizzle relationships in marine stratocumulus are presented from the second Marine Stratus/Stratocumulus Experiment (MASE-II) carried out in July 2007 over the eastern Pacific near Monterey, California.

Characterization of HRRR-simulated rotor layer wind speeds and clouds along the coast of California [PDF]

Wind Energy Science
Stratocumulus clouds, with their low cloud base and top, affect the atmospheric boundary layer wind and turbulence profile, thereby modulating wind energy resources.

Cloud System Evolution in the Trades (CSET): Following the Evolution of Boundary Layer Cloud Systems with the NSFNCAR GV [PDF]

, 2019
The Cloud System Evolution in the Trades (CSET) study was designed to describe and explain the evolution of the boundary layer aerosol, cloud, and thermodynamic structures along trajectories within the North Pacific trade winds.

Sensitivity to Physical and Numerical Aspects of Large-Eddy Simulation of Stratocumulus

Monthly Weather Review, 2019
A series of numerical experiments where both physical and numerical model parameters are varied with respect to a reference setup is used to investigate the physics of a stratocumulus cloud and the performance of a large-eddy simulation (LES) model ...

Large‐eddy simulation of subtropical cloud‐topped boundary layers: 2. Cloud response to climate change

Journal of Advances in Modeling Earth Systems, 2017
How subtropical marine boundary layer (MBL) clouds respond to warming is investigated using large‐eddy simulations (LES) of a wide range of warmer climates, with CO2 concentrations elevated by factors 2–16. In LES coupled to a slab ocean with interactive

Slow Manifolds and Multiple Equilibria in Stratocumulus-Capped Boundary Layers

Journal of Advances in Modeling Earth Systems, 2010
In marine stratocumulus-capped boundary layers under strong inversions, the timescale for thermodynamic adjustment is roughly a day, much shorter than the multiday timescale for inversion height adjustment. Slow-manifold analysis is introduced to exploit

Ground-based observations of cloud and drizzle liquid water path in stratocumulus clouds

Atmospheric Measurement Techniques, 2019
. The partition of cloud and drizzle water path in precipitating clouds plays a key role in determining the cloud lifetime and its evolution. A technique to quantify cloud and drizzle water path by combining measurements from a three-channel microwave ...

A New TKE‐Based Parameterization of Atmospheric Turbulence in the Canadian Global and Regional Climate Models

Journal of Advances in Modeling Earth Systems, 2019
A new semi‐empirical turbulence parameterization is presented. Key features of the scheme include representation of turbulent diffusivities in terms of the turbulent kinetic energy that is determined by solving a quasi‐equilibrium form of the equation ...

Satellite‐Based Estimation of Cloud Top Radiative Cooling Rate for Marine Stratocumulus

Geophysical Research Letters, 2019
Cloud top radiative cooling rate (CTRC) is the leading term in the energy budget of a marine boundary layer capped by stratocumulus. It plays a significant role in the formation, evolution, and maintenance of the stratocumulus cloud system.
