Observations of Drizzle in Nocturnal Marine Stratocumulus [PDF]
Journal of the Atmospheric Sciences, 2005 Abstract In situ and radar data from the second field study of the Dynamics and Chemistry of Marine Stratocumulus (DYCOMS-II) have been used to study drizzle in stratocumulus. Measurements indicate that drizzle is prevalent. During five of seven analyzed flights precipitation was evident at the surface, and on roughly a third of the ...

Where is the Interface of the Stratocumulus-Topped PBL? [PDF]
Journal of the Atmospheric Sciences, 2005 Abstract Various locally defined (not horizontal mean) interfaces between the stratocumulus-topped PBL and the free atmosphere are investigated using a fine-resolution large-eddy simulation with a vertical grid spacing of about 4 m. The local cloud-top height is found to be always below the height where the maximum gradient of the local ...

Impact of the representation of marine stratocumulus clouds on the anthropogenic aerosol effect [PDF]
Atmospheric Chemistry and Physics, 2014 Stratocumulus clouds are important for climate as they reflect large amounts of solar radiation back into space. However they are difficult to simulate in global climate models because they form under a sharp inversion and are thin. A comparison of model

On the Factors Modulating the Stratocumulus to Cumulus Transitions [PDF]
Journal of the Atmospheric Sciences, 2011 Abstract Large-eddy simulation (LES) is used to explore the role of various processes in regulating the stratocumulus to cumulus transition (SCT). Simulations are based on a composite case derived from a Lagrangian analysis of 2 yr of data from the northeastern Pacific.

The Sensitivity of Numerical Simulations of Cloud‐Topped Boundary Layers to Cross‐Grid Flow
Journal of Advances in Modeling Earth Systems, 2018 In mesoscale and global atmospheric simulations with large horizontal domains, strong horizontal flow across the grid is often unavoidable, but its effects on cloud‐topped boundary layers have received comparatively little study.

POCKETS OF OPEN CELLS AND DRIZZLE IN MARINE STRATOCUMULUS [PDF]
Bulletin of the American Meteorological Society, 2005 Data from recent field studies in the northeast and southeast Pacific are used to investigate pockets of open cells (POCs) that are embedded in otherwise uniform stratocumulus. The cellular structure within a POC resembles broader regions of open cellular convection typically found further offshore.

On the importance of cumulus penetration on the microphysical and optical properties of stratocumulus clouds [PDF]
Atmospheric Chemistry and Physics, 2005 Owing to their extensive spatial coverage, stratocumulus clouds play a crucial role in the radiation budget of the earth. Climate models need an accurate characterisation of stratocumulus in order to provide an accurate forecast.

How large-scale subsidence affects stratocumulus transitions [PDF]
Atmospheric Chemistry and Physics, 2016 Some climate modeling results suggest that the Hadley circulation might weaken in a future climate, causing a subsequent reduction in the large-scale subsidence velocity in the subtropics.

Deconvolution of boundary layer depth and aerosol constraints on cloud water path in subtropical stratocumulus decks [PDF]
Atmospheric Chemistry and Physics, 2020 The liquid water path (LWP) adjustment due to aerosol–cloud interactions in marine stratocumulus remains a considerable source of uncertainty for climate sensitivity estimates.
