Marine stratocumulus structure

Remote Sensing of Environment, 1989
Thirty-three Landsat TM scenes of California stratocumulus cloud fields were acquired as part of the FIRE Marine Stratocumulus Intensive Field Observations in July 1987. They exhibit a wide variety of stratocumulus structures. Analysis has so far focused upon the July 7 scene, in which aircraft from NASA, NCAR, and the British Meteorological Office ...

Holes and Entrainment in Stratocumulus

Journal of the Atmospheric Sciences, 2005
Abstract Aircraft flights through stratocumulus clouds (Sc) during the Dynamics and Chemistry of Marine Stratocumulus II (DYCOMS-II) study off the California coast found narrow in-cloud regions with less liquid water content (LWC) and cooler temperatures than average background values. The regions are named cloud holes and are assumed to

Fogs and Stratocumulus Clouds

2011
Abstract Chapter 6 provides an overview of the dynamics of fogs and stratocumulus clouds. Included are fog formation mechanisms and various forcing factors that influence fog occurrence and intensity. Likewise factors influencing boundary layer cloud occurrence and intensity are reviewed along with discussions of models used to describe and predict ...

A Stratocumulus Model with an Internal Circulation

Journal of the Atmospheric Sciences, 1986
Abstract An updraft and downdraft circulation model based on a mass flux representation of convective fluxes is incorporated into a classic cloud-topped, mixed layer model. The convective mass flux is assumed to be proportional to the convective velocity scale.

Marine stratocumulus climatologies

International Journal of Climatology, 1991
AbstractConditions favourable to the formation and maintenance of marine stratocumulus cloud decks commonly occur in the subtropical latitudes off the west coasts of the major continents. The cloud decks over the eastern North and South Pacific and the eastern South Atlantic are well‐established examples of the phenomenon; the eastern North Atlantic ...

Microphysical properties of stratocumulus clouds

Atmospheric Research, 2000
Data collected in situ with the Meteo-France Merlin-IV instrumented aircraft during the EUCREX mission 206 are analyzed to document cloud properties that are relevant to the calculation of cloud radiative properties. Ascents and descents through the cloud layer reveal that most of the vertical profiles of liquid water content (LWC) and droplet sizes ...

Orographic Influences on Subtropical Stratocumulus

Journal of the Atmospheric Sciences, 2006
Abstract The impact of South American orography on subtropical stratocumulus clouds off the Peruvian coast is investigated in the context of an atmospheric general circulation model. It is found that stratocumulus incidence is significantly reduced when South American orography is removed.

Microphysical and radiative properties of stratocumulus

Physics and Chemistry of the Earth, Part B: Hydrology, Oceans and Atmosphere, 1999
Abstract During the Cloudy Column project of the Aerosol Characterisation Experiment (ACE2) stratocumulus clouds formed in air masses of different origins have been sampled. The paper presents results from in-situ measurements and the comparison of the derived radiative properties with those remotely sensed.

Cloud-Top Entrainment in Stratocumulus Clouds

Annual Review of Fluid Mechanics, 2017
Cloud entrainment, the mixing between cloudy and clear air at the boundary of clouds, constitutes one paradigm for the relevance of small scales in the Earth system: By regulating cloud lifetimes, meter- and submeter-scale processes at cloud boundaries can influence planetary-scale properties.

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 ...
