Abstract: Laboratory experiments were performed to investigate interactions between small (400?900 ?m) precipitation-size drops at temperatures colder than 0°C. The investigation was accomplished by creating a light shower of ...

Abstract: A theoretical model has been formulated to study by numerical techniques the efficiency E with which columnar ice crystals grown at temperatures between ?3 and ?8°C are captured in a cloud by relatively large, supercooled ...

Abstract: A case of a waterspout that developed from a relatively small cumulus cloud is presented. This is believed to be the first time that detailed Doppler radar information on a parent cloud has ever been collected. Vertical ...

Abstract: In this paper, the authors show how the variability of the water content in individual clouds, the complexity of individual cloud structure, and the lateral and vertical heterogeneity of the distribution of individual ...

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 ...
