A new parameterization of marine stratocumulus and shallow cumulus clouds for climate models
A new parameterization of marine stratocumulus and shallow cumulus clouds is presented. The parameterization consists of a mass flux cumulus convection scheme coupled to a 1.5 order Turbulence Closure Model (TCM) with an entrainment closure for convective boundary layers. The mass flux scheme is based on a buoyancy sorting ...
Convective momentum transport over the tropical Pacific
The vertical transport of horizontal momentum by cumulus convection is investigated in observations and model simulations of the Tropical Ocean Global Atmosphere Coupled Ocean-Atmosphere Response Experiment (TOGA COARE). Estimates of convective momentum transport (CMT) are obtained from the COARE momentum budget, aircraft ...
An empirical study of the lidar ratio and its variability, with implications for determining climate forcing by satellite-borne lidar
It is well-established that atmospheric aerosols play a role in determining the radiative balance of the Earth. Further, it is believed that anthropogenic aerosols may be causing significant cooling at the Earth's surface (the "aerosol direct effect"). Several methods have been used to quantify this effect, but the uncertainties ...
