(author)Results are presented of the GASS/EUCLIPSE single-column model intercomparison study on the subtropical marine low-level cloud transition. A central goal is to establish the performance of state-of-the-art boundary-layer schemes for weather and climate models for this cloud regime, using large-eddy simulations of the same scenes as a...journal article 2017

Van der Dussen, J.J. (author), De Roode, S.R. (author), Dal Gesso, S. (author), Siebesma, A.P. (author)Twenty-five large-eddy simulations are performed to study how free tropospheric thermodynamic conditions control equilibrium state solutions of stratocumulus-topped marine boundary layers. In particular, we systematically vary the lower tropospheric stability (LTS) and a similar measure for the bulk humidity difference between the 700 hPa level...journal article 2015

(author)Six Single-Column Model (SCM) versions of climate models are evaluated on the basis of their representation of the dependence of the stratocumulus-topped boundary layer regime on the free tropospheric thermodynamic conditions. The study includes two idealized experiments corresponding to the present-day and future climate conditions in order to...journal article 2015

Dal Gesso, S. (author)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 extension is generally quantified by the...doctoral thesis 2015

De Roode, S.R. (author), Siebesma, A.P. (author), Dal Gesso, S. (author), Jonker, H.J.J. (author), Schalkwijk, J. (author), Sival, J. (author)A mixed-layer model is used to study the response of stratocumulus equilibrium state solutions to perturbations of cloud controlling factors which include the sea surface temperature, the specific humidity and temperature in the free troposphere, as well as the large-scale divergence and horizontal wind speed. In the first set of experiments, we...journal article 2014
