RISScale Dependency of Total Water Variance and Its Implication for Cloud Parameterizations
Publisher: American Meteorological Society
Abstract: he scale dependency of variance of total water mixing ratio is explored by analyzing data from a general circulation model (GCM), a numerical weather prediction model (NWP), and large-eddy simulations (LESs). For clarification, ...
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 ...
Long-Term Observations and High-Resolution Modeling of Midlatitude Nocturnal Boundary Layer Processes Connected to Low-Level Jets
Publisher: American Meteorological Society
Abstract: AbstractLow-level-jet (LLJ) periods are investigated by exploiting a long-term record of ground-based remote sensing Doppler wind lidar measurements supported by tower observations and surface flux measurements at the ...
Earth System Science Frontiers - an ECS perspective
Publisher: American Meteorological Society
Abstract: he exigencies of the global community towards Earth system science will increase in the future as population, economies and the human footprint on the planet continue to grow. This growth, combined with intensifying ...
