A Dual Mass Flux Framework for Boundary Layer Convection. Part II: Clouds
Publisher: American Meteorological Society
Abstract: This paper presents the extension of the eddy diffusivity mass flux (EDMF) framework for turbulent transport into the statistical modeling of boundary layer clouds. The advection?diffusion decomposition that defines EDMF ...
A Dual Mass Flux Framework for Boundary Layer Convection. Part I: Transport
Publisher: American Meteorological Society
Abstract: This study considers the question of what is the least complex bulk mass flux framework that can still conceptually reproduce the smoothly varying coupling between the shallow convective cloud layer and the subcloud mixed ...
Impact Mechanisms of Shallow Cumulus Convection on Tropical Climate Dynamics
Publisher: American Meteorological Society
Abstract: Subtropical shallow cumulus convection is shown to play an important role in tropical climate dynamics, in which convective mixing between the atmospheric boundary layer and the free troposphere initiates a chain of ...
Investigating the Scale Adaptivity of a Size-Filtered Mass Flux Parameterization in the Gray Zone of Shallow Cumulus Convection
Publisher: American Meteorological Society
Abstract: AbstractIn this study, the scale adaptivity of a new parameterization scheme for shallow cumulus clouds in the gray zone is investigated. The eddy diffusivity/multiple mass flux [ED(MF)n] scheme is a bin-macrophysics scheme ...
Investigating the Diurnal Evolution of the Cloud Size Distribution of Continental Cumulus Convection Using Multiday LES
Publisher: American Meteorological Society
Abstract: The diurnal dependence of cumulus cloud size distributions over land is investigated by means of an ensemble of large-eddy simulations (LESs). A total of 146 days of transient continental shallow cumulus are selected and ...
ARM’s Impact on Numerical Weather Prediction at ECMWF

Modeled Contrast in the Response of the Surface Energy Balance to Heat Waves for Forest and Grassland
Publisher: American Meteorological Society
Abstract: bservations have shown that differences in surface energy fluxes over grasslands and forests are amplified during heat waves. The role of land?atmosphere feedbacks in this process is still uncertain. In this study, a ...
Simulations of Trade Wind Cumuli under a Strong Inversion
Publisher: American Meteorological Society
Abstract: The fifth intercomparison of the Global Water and Energy Experiment Cloud System Studies Working Group 1 is used as a vehicle for better understanding the dynamics of trade wind cumuli capped by a strong inversion. The ...
