Observations of stratocumulus cloud break-up over land

Quarterly Journal of the Royal Meteorological Society, 1999
AbstractDetailed measurements were made during three episodes of boundary‐layer stratocumulus clouds occumng at Cardington, Bedfordshire, UK, using the UK Meteorological Oftice tethered‐balloon system. no cases were of cloud which dispersed or partly dispersed during the day, and the other was of persistent cloud.

Stratocumulus Cloud Field Reflected Fluxes: The Effect of Cloud Shape

Journal of the Atmospheric Sciences, 1984
The reflected fluxes of stratocumulus cloud fields are calculated as a function of sky cover aspect ratio and cloud shape. In order to obtain a better fit with general circulation models (GCMs), cloud liquid water volume values were kept invariant relative to cloud shape.

What drives increased evaporation at cloud top in polluted stratocumulus clouds?

2022
<p>Observations and simulations show that an increase in aerosol concentration typically leads to an increase in liquid water path in precipitating stratocumulus clouds due to precipitation suppression, but once precipitation is fully suppressed, further increases in aerosol concentration typically lead to a reduction in liquid water path

Aerosol-Cloud-Precipitation Interactions in Marine Stratocumulus Clouds

2013
Marine stratocumulus clouds are generally optically thick and shallow, exerting a net cooling influence on climate. Changes in atmospheric aerosol levels alter cloud microphysics (e.g., droplet size) and cloud macrophysics (e.g., liquid water path, cloud thickness), thereby affecting cloud albedo and Earth’s radiative balance. To understand the aerosol-

Saturation Point Structure of Marine Stratocumulus Clouds

Journal of the Atmospheric Sciences, 1988
An investigation of the microstructure of a Pacific stratocumulus capped boundary layer is presented. A complex structure of three branches, identified using conserved variable diagrams, is found to correspond well to a conceptual model for the unstable, radiatively cooled cloud topped boundary layer.

A Radiative Parameterization of Stratocumulus Cloud Fields

Journal of the Atmospheric Sciences, 1985
A parameterization scheme is presented which allows the calculation of radiative reflected fluxes from a stratocumulus cloud field. The scheme is based upon plane-parallel calculations, such as delta-Eddington, and a simple procedure is outlined by which the plane-parallel fluxes may be transformed to those of the broken cloud case.

Stratocumulus Cloud Properties Derived from the Multichannel Cloud Radiometer

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
An airborne multispectral scanning radiometer was flown over marine stratocumulus clouds near Monterey, CA during July 2003. Radiance observed in a visible and near-infrared channel is compared to modeled radiance to estimate cloud drop effective radius and liquid water content. Results are compared to in situ measurements and to estimates derived from

Stratocumulus clouds in a changing climate

2015
The clouds that form in the atmospheric region close to the Earth surface work as a parasol for our planet. Their primary effect is to reflect the incoming solar radiation and in this way to cool the Earth. Tlie more extensive and the thicker they are, the more radiation is reflected back to space.

The Retrieval of Stratocumulus Cloud Properties by Ground-Based Cloud Radar

Journal of Applied Meteorology, 1997
The radiative characteristics of stratocumulus clouds are dependent upon their microphysical properties, primarily the liquid water content and effective radius of the drop population. Aircraft observations of droplet spectra in warm stratocumulus over the North Atlantic and around the British Isles by the Hercules C-130 aircraft of the U.K ...

The interaction of aerosol with stratocumulus cloud

1996
Publisher Summary This chapter presents model of the stratocumulus capped boundary layer, and describes the evolution of the atmospheric aerosol, as it undergoes multiple cycles of mixing through the depth of the boundary layer. The model includes aqueous phase chemical processes occurring in droplets formed on cloud condensation nuclei of known ...
