RISA Binned Approach to Cloud-Droplet Riming Implemented in a Bulk Microphysics Model
Publisher: American Meteorological Society
Abstract: This paper presents the development and application of a binned approach to cloud-droplet riming within a bulk microphysics model. This approach provides a more realistic representation of collision?coalescence that occurs ...
A Large-Droplet Mode and Prognostic Number Concentration of Cloud Droplets in the Colorado State University Regional Atmospheric Modeling System (RAMS). Part II: Sensitivity to a Colorado Winter Snowfall Event
Publisher: American Meteorological Society
Abstract: This paper is the second in a two-part series describing recent additions to the microphysics module of the Regional Atmospheric Modeling System (RAMS) at Colorado State University. These changes include the addition of a ...
Simulations of the North American Monsoon System. Part I: Model Analysis of the 1993 Monsoon Season
Publisher: American Meteorological Society
Abstract: The North American monsoon system is known to produce significant summertime precipitation on the west coast of Mexico and the southwestern United States, with some areas receiving greater than 50% of their yearly rainfall ...

Publisher: American Meteorological Society
Abstract: he Colorado State University (CSU) Regional Atmospheric Modeling System (RAMS) has undergone development focused on improving the treatment of aerosols in the microphysics model, with the goal of examining the impacts of ...
The Cumulative Impact of Cloud Droplet Nucleating Aerosols on Orographic Snowfall in Colorado
Publisher: American Meteorological Society
Abstract: Hygroscopic pollution aerosols have the potential to alter winter orographic snowfall totals and spatial distributions by modification of high-elevation supercooled orographic clouds and the riming process. The authors ...
Aerosol Impacts on the Microphysical Growth Processes of Orographic Snowfall
Publisher: American Meteorological Society
Abstract: he Regional Atmospheric Modeling System was used to simulate four winter snowfall events over the Park Range of Colorado. For each event, three hygroscopic aerosol sensitivity simulations were performed with initial aerosol ...

Publisher: American Meteorological Society
Influence of Cloud Condensation Nuclei on Orographic Snowfall
Publisher: American Meteorological Society
Abstract: Pollution aerosols acting as cloud condensation nuclei (CCN) have the potential to alter warm rain clouds via the aerosol first and second indirect effects in which they modify the cloud droplet population, cloud lifetime ...
Impact of Cloud-Nucleating Aerosols in Cloud-Resolving Model Simulations of Warm-Rain Precipitation in the East China Sea
Publisher: American Meteorological Society
Abstract: Cloud-nucleating aerosols emitted from mainland China have the potential to influence cloud and precipitation systems that propagate through the region of the East China Sea. Both simulations from the Spectral Radiation-Transport ...
