On the importance of cumulus penetration on the microphysical and optical properties of stratocumulus clouds
Owing to their extensive spatial coverage, stratocumulus clouds play a crucial role in the radiation budget of the earth. Climate models need an accurate characterisation of stratocumulus in order to provide an accurate forecast. However, remote sensing as well as in-situ observations reveal that on several occasions, cumulus clouds present below the stratocumulus, often have a significant impa...
متن کاملMarine Boundary Layer Cloud Observations in the Azores
The recent deployment of the Atmospheric Radiation Measurement Program (ARM) Mobile Facility at Graciosa Island, Azores, in the context of the Clouds, Aerosol and Precipitation in theMarine Boundary Layer (CAP-MBL) field campaign added the most extensive (19 months) and comprehensive dataset of marine boundary layer (MBL) clouds to date. Cloud occurrence is high (60%–80%), with a summertime min...

The recent deployment of the ARM Mobile Facility at the Graciosa Island, Azores in the context of the Clouds, Aerosol and Precipitation in the Marine Boundary Layer (CAPMBL) field campaign added the most extensive and comprehensive dataset of MBL clouds to date (April 2009–December 2010). Cloud occurrence is high (60–80%) with a summertime minimum. Liquid precipitation, diagnosed as the detecti...
متن کاملModeling microphysical effects of entrainment in clouds observed during EUCAARI-IMPACT field campaign
This paper discusses aircraft observations and large-eddy simulation (LES) modeling of 15 May 2008, North Sea boundary-layer clouds from the EUCAARIIMPACT field campaign. These clouds are advected from the northeast by the prevailing lower-tropospheric winds and featured stratocumulus-over-cumulus cloud formations. An almost-solid stratocumulus deck in the upper part of the relatively deep, wea...
متن کاملA Qualitative View Of Clouds In The Equatorial Trough Zone
Oceanic tropical clouds are observed to occur at various length scales over the equatorial trough zone (an area around the intertropical convergence zone or ITCZ). As one proceeds from the subtropics towards the equator, the cloud types range from small stratocumulus, small cumulus (including trade cumulus), cumulus, cumulonimbus (isolated) and large mesoscale convective systems (MCSs)with a co...
