Low cloud precipitation climatology in the southeastern Pacific marine stratocumulus region using CloudSat

open access: yesEnvironmental Research Letters, 2013
A climatology of low cloud surface precipitation occurrence and intensity from the new CloudSat 2C-RAIN-PROFILE algorithm is presented from June 2006 through December 2010 for the southeastern Pacific region of marine stratocumulus.

Idealized large-eddy simulations of stratocumulus advecting over cold water. Part 1: Boundary layer decoupling

open access: yesJournal of the Atmospheric Sciences, 2021
We explore the decoupling physics of a stratocumulus-topped boundary layer (STBL) moving over cooler water, a situation mimicking the warm air advection (WADV).

On the role of the stratiform cloud scheme in the inter‐model spread of cloud feedback

open access: yesJournal of Advances in Modeling Earth Systems, 2017
This study explores the role of the stratiform cloud scheme in the inter‐model spread of cloud feedback. Six diagnostic cloud schemes used in various CMIP (Coupled Model Intercomparison Experiment] climate models are implemented (at low and midlevels ...

Diurnal cycle of the semi-direct effect from a persistent absorbing aerosol layer over marine stratocumulus in large-eddy simulations

open access: yesAtmospheric Chemistry and Physics, 2020
. The rapid adjustment, or semi-direct effect, of marine stratocumulus clouds to elevated layers of absorbing aerosols may enhance or dampen the radiative effect of aerosol–radiation interactions.

Contrasting characteristics of open- and closed- cellular stratocumulus cloud in the Eastern North Atlantic

open access: yesAtmospheric Chemistry and Physics, 2021
. Extensive regions of marine boundary layer cloud impact the radiative balance through their significant shortwave albedo while having little impact on outgoing longwave radiation.

Competing Effects of Droplet Sedimentation and Wind Shear on Entrainment in Stratocumulus

open access: yesJournal of Advances in Modeling Earth Systems, 2019
The joint effect of droplet sedimentation and wind shear on cloud top entrainment in stratocumulus is investigated with direct numerical simulations. Although it is well understood that droplet sedimentation weakens entrainment while wind shear enhances ...

An observation-based method to assess tropical stratocumulus and shallow cumulus clouds and feedbacks in CMIP6 and CMIP5 models

open access: yesEnvironmental Research Communications, 2023
In the Earth system models (ESMs) participating in the Coupled Models Intercomparison Project phase 6 (CMIP6), the tropical low-cloud feedback is 50% more positive than its predecessors (CMIP5) and continues to dominate the spread in simulated climate ...

Network approach to patterns in stratocumulus clouds [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance Large parts of the subtropical oceans are covered by stratocumulus (Sc) cloud decks that self-organize into honeycomb-like hexagonal patterns. These clouds cool the planet by reflecting solar radiation. Sc patterns are controlled by processes from the micrometer to the kilometer scale.

Cloud and boundary layer interactions over the Arctic sea ice in late summer [PDF]

open access: yes, 2013
Observations from the Arctic Summer Cloud Ocean Study (ASCOS), in the central Arctic sea-ice pack in late summer 2008, provide a detailed view of cloud- atmosphere-surface interactions and vertical mixing processes over the sea-ice environment ...

Cloud regimes as phase transitions

open access: yesGeophysical Research Letters, 2016
Clouds are repeatedly identified as a leading source of uncertainty in future climate predictions. Of particular importance are stratocumulus clouds, which can appear as either (i) closed cells that reflect solar radiation back to space or (ii) open ...
