Abstract: The collision efficiency between plate-like ice crystals and supercooled drops is computed using a modified version of the trajectory model developed by Lew and Pruppacher. It is found that whereas the collision efficiencies ...

Abstract: eteorological factors affect the concentrations and distributions of pollutants during episodes of degraded air quality. Over the last 10 years, the upper Green River basin (UGRB) of Sublette County, Wyoming, has experienced ...

Abstract: Natural and artificial snowflakes have been rimed both in free fall and while suspended on a thin flexible fiber in the UCLA cloud tunnel. The results of these experiments show that during the early stage of riming, the ...

Abstract: The effects of porosity on the accretional growth characteristics of ice crystal aggregates (snowflakes) are investigated by riming circular disks of ice in a cloud tunnel. Twelve disk models were used, sized 5 to 6 mm and ...
