Modification of Precipitation from Warm Clouds—A Review
Publisher: American Meteorological Society
Abstract: This review is begun with a brief summary of the current status of our understanding of the physics of precipitation in warm clouds. The impact of warm-cloud precipitation processes on the evolution of the ice phase in ...
On Parameterization of Turbulent Transport in Cumulus Clouds
Publisher: American Meteorological Society
Abstract: A one-dimensional time-dependent cumulus model is developed and discussed. Data predicted by the model along with a bulk entrainment model are compared with a case study observation and Warner's mean profile of Q/QA. While ...
Numerical Simulation of Precipitation Development in Supercooled Cumuli—Part II
Publisher: American Meteorological Society
Abstract: A numerical model of supercooled cumuli is developed and discussed. Water substance in the model is idealized to be partitioned into the five phase components; namely, water vapor, liquid cloud water, liquid rainwater, ...
Numerical Simulation of Precipitation Development in Supercooled Cumuli—Part I
Publisher: American Meteorological Society
Abstract: Based on numerical experiments in droplet collection with a stochastic model similar to Berry's, a new quantitative definition of autoconversion is discussed. The new formulation of autoconversion is compared with Kessler's ...
A Method for Forecasting Cloud Condensation Nuclei Using Predictions of Aerosol Physical and Chemical Properties from WRF/Chem
Publisher: American Meteorological Society
Abstract: odel investigations of aerosol?cloud interactions across spatial scales are necessary to advance basic understanding of aerosol impacts on climate and the hydrological cycle. Yet these interactions are complex, involving ...
A Modeling Investigation of the Potential Impacts of Pollution Aerosols on Hurricane Harvey
Publisher: American Meteorological Society
The Sensitivity of a Simulated Extratropical Mesoscale Convective System to Longwave Radiation and Ice-Phase Microphysics
Publisher: American Meteorological Society
Abstract: A two-dimensional, nonhydrostatic version of the Colorado State University Regional Atmospheric Modeling System (RAMS) was applied to the simulation of a midlatitude, continental mesoscale convective system. A control ...
The Effect of Pollution Aerosol on Wintertime Orographic Precipitation in the Colorado Rockies Using a Simplified Emissions Scheme to Predict CCN Concentrations
Publisher: American Meteorological Society
Abstract: he impacts of enhanced CCN concentrations on various cloud and precipitation systems are potentially significant both to the large-scale climate system and local precipitation patterns. Precipitating stable orographic cloud ...
Large Eddy Simulation of Shallow Cumulus Convection during BOMEX: Sensitivity to Microphysics and Radiation
Publisher: American Meteorological Society
Abstract: A number of large eddy simulations with the Regional Atmospheric Modeling System have been made to study the sensitivity of shallow marine cumulus convection to different microphysics and radiation schemes. In particular, ...
