Abstract: Temperature and moisture profiles from soundings obtained over the central Atlantic during the Atlantic Trade-Wind Experiment were used to determine if cloud-top entrainment instability can explain observed variations in ...

Abstract: irculations in and around cumulus clouds are inferred by using a passive tracer (radar chaff) and an airborne cloud radar during the Barbados Aerosol Cloud Experiment (BACEX). The radar chaff elements used for this experiment ...

Abstract: Fair-weather cumuli are fundamental in regulating the vertical structure of water vapor and entropy in the lowest 2?3 km of the earth?s atmosphere over vast areas of the oceans. In this study, a long record of profiling ...

Abstract: The turbulent-scale vertical velocity structure in a continental stratocumulus cloud is studied using a 3-mm wavelength Doppler radar operating in a vertically pointing mode. The radar observations provided 30-m sampling ...

Abstract: A scheme for parameterizing the fractional cloud coverage of trade cumuli is developed which gives the cloud cover in terms of the cloud-layer relative humidity and the liquid water content of the convective elements. This ...

Abstract: A scheme for parameterizing the effects of cumulus convection for the maintenance of the thermodynamic structure of the tropical atmosphere is described. This parameterization is used in a one-dimensional model that ...

Abstract: Cloud fraction observations and trade-wind inversion base heights from both GATE and the undisturbed period of ATEX are examined for diurnal variation. The cloud fraction tends to be larger in the morning than in the ...

Abstract: Several applications of a simple layered model of the temperature and moisture structure of the trade-wind boundary layer are considered. The formation of the trade inversion in the wake of disturbed conditions is simulated. ...

Abstract: The formation of fair-weather cumuli (FWC) has been analyzed in this study based on both a simple mixed layer model and a subset of the data collected from the Atmospheric Radiation Measurement (ARM) Program at the southern ...

Abstract: A mean-gradient model of the dry convective boundary layer is developed using a convective mass flux representation of the turbulent fluxes. A top-hat model of thermals is used to represent the average characteristics of ...
