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

Combining regional mesh refinement with vertically enhanced physics to target marine stratocumulus biases as demonstrated in the Energy Exascale Earth System Model version 1 [PDF]

Geoscientific Model Development, 2023
In this paper we develop a novel framework aimed to significantly reduce biases related to marine stratocumulus clouds in general circulation models (GCMs) while circumventing excessive computational cost requirements.

Accelerating Large‐Eddy Simulations of Clouds With Tensor Processing Units

Journal of Advances in Modeling Earth Systems, 2023
Clouds, especially low clouds, are crucial for regulating Earth's energy balance and mediating the response of the climate system to changes in greenhouse gas concentrations.

Evaluation of turbulent dissipation rate retrievals from Doppler Cloud Radar [PDF]

, 2012
Turbulent dissipation rate retrievals from cloud radar Doppler velocity measurements are evaluated using independent, in situ observations in Arctic stratocumulus clouds. In situ validation data sets of dissipation rate are derived using sonic anemometer

First Observational Perspectives of “Millipede Clouds” Over the Eastern Pacific Ocean

Geophysical Research Letters, 2023
The fundamental features of one kind of rarely known stratocumulus, which was termed as “Millipede Cloud,” occurred over the Eastern Pacific Ocean in 2017 were first documented by using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite ...

Coastal Stratocumulus cloud edge forecasts [PDF]

Solar Energy, 2018
Abstract Improved coastal stratocumulus (Sc) cloud forecasts are needed because traditional satellite cloud motion vectors (CMV) do not accurately predict how Sc clouds move or dissipate in time, which often results in an underprediction of irradiance in the morning hours. CMV forecasts assume clouds move in the direction of the average regional wind

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.

The Marine Stratus/Stratocumulus Experiment (MASE): Aerosol‐cloud relationships in marine stratocumulus [PDF]

Journal of Geophysical Research: Atmospheres, 2007
The Marine Stratus/Stratocumulus Experiment (MASE) field campaign was undertaken in July 2005 off the coast of Monterey, California to evaluate aerosol‐cloud relationships in the climatically important regime of eastern Pacific marine stratocumulus. Aerosol and cloud properties were measured onboard the Center for Interdisciplinary Remotely‐Piloted ...

Study of the Aerosol Indirect Effect by Large-Eddy Simulation of Marine Stratocumulus [PDF]

, 2005
A total of 98 three-dimensional large-eddy simulations (LESs) of marine stratocumulus clouds covering both nighttime and daytime conditions were performed to explore the response of cloud optical depth (τ) to various aerosol number concentrations (Na ...
