Factors Governing Cloud Growth and Entrainment Rates in Shallow Cumulus and Cumulus Congestus During GoAmazon 2014/2015
Shallow cumulus and cumulus congestus clouds play an important role in the large-scale tropical circulation by mixing heat and moisture vertically and preconditioning the environment for deeper convection. Different representations of these shallow clouds also account for much of the spread in …

Modeling and Observational Studies of Shallow Cumulus Convection Over the Indian Ocean: Aerosol and Meteorological Effects on Diurnal Cycles
… a dry and stable layer had critical impacts on cumulus cloud properties, turbulence and lateral detrainment rate, and on how anthropogenic aerosols affect these quantities. For the range of meteorological conditions observed during INDOEX the semi-direct effect always dominated indirect effects, …

The macrophysical properties of shallow cumulus clouds from moderate- and high-resolution satellite data collected over the tropical western Pacific
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2025-08-01

Understanding precipitation, cold pools, and cloud arcs in the tropics
Before the Rain in Cumulus over the Ocean (RICO) field campaign that took place near Antigua and Barbuda from 2004-2005, it was thought that most trade wind cumulus clouds do not precipitate. The main goal of the RICO field campaign was to study rain in tropical marine cumuli and how this rain …

On the paradox of convectively-coupled waves
… the forced response of waves on a linearized, shallow water beta-plane in an attempt to develop some gross understanding of the properties of convectively coupled waves. Two concepts are central to this new theory: (i) a convectively coupled wave is a forced wave; (ii) a convectively coupled …

A numerical model study of the stratocumulus-topped marine boundary layer
… quantitatively reproduce processes in the stratocumulus topped boundary layer using measurements of atmospheric turbulence from aircraft from the North Sea and the subtropical North Atlantic and North Pacific. The model is robust to changes in the mixing length coefficients used in the turbulence …

Development of an accurate 3D Monte Carlo broadband atmospheric radiative transfer model
… and remote sensing observations of clouds, from shallow cumulus to deep convective clouds, and given our ever advancing technological capabilities, these approximations have been exposed as inappropriate in many situations. This presents a need for accurate 3D spectral and broadband radiative …

Cloud drop effective radius for trade wind cumuli observed during RICO by aircraft and MODIS
… have been for stratiform clouds, not for cumulus. Here, we use in-situ aircraft measurements from RICO (“Rain In shallow Cumulus over the Ocean”) for these cumuli, and investigate how they compare to satellite retrievals from MODIS (“Moderate Resolution Imaging Spectroradiometer”). In …

Characterization of the role of precipitation in tropical cyclone intensification
… diabatic heating and vertical fluxes from cumulus congestus, deep convection, and convective bursts near RI onset with a secondary heating role apparently associated with stratiform precipitation, whereas the high shear simulation is nearly-entirely CB driven. Within the low shear …
