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

Evaluation of the ECHAM4 cloud-turbulence scheme for Stratocumulus
Meteorologische Zeitschrift, 2000 The behavior of the ECHAM4 cloud and turbulence scheme is evaluated for an idealized case of Stratocumulus. It is shown that the E-l turbulence closure that is used is sensitive to instabilities.

Vertical grid refinement for stratocumulus clouds in the radiation scheme of the global climate model ECHAM6.3-HAM2.3-P3 [PDF]
Geoscientific Model Development, 2021 In this study, we implement a vertical grid refinement scheme in the radiation routine of the global aerosol–climate model ECHAM-HAM, aiming to improve the representation of stratocumulus clouds and address the underestimation of their cloud cover.

Monthly Weather Review, 2012 Abstract This paper reviews the current knowledge of the climatological, structural, and organizational aspects of stratocumulus clouds and the physical processes controlling them. More of Earth’s surface is covered by stratocumulus clouds than by any other cloud type making them extremely important for Earth’s energy balance, primarily ...

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

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.

The diurnal stratocumulus-to-cumulus transition over land in southern West Africa [PDF]
Atmospheric Chemistry and Physics, 2020 The misrepresentation of the diurnal cycle of boundary layer clouds by large-scale models strongly impacts the modeled regional energy balance in southern West Africa. In particular, recognizing the processes involved in the maintenance and transition of
