Abstract: A hailstone model is developed which simulates both wet and dry hailstone growth and partial or complete melting as the hailstone falls to the ground. The simulation is obtained by a consideration of the mass and heat ...

Abstract: Twelve thunderstorm updrafts were analyzed in detail and a composite average derived. The updrafts were normalized in width and maximum intensity so they could he compared on the same scale. The composite average was ...

Abstract: Aircraft observations and high resolution Landsat Multispectral Scanner digital data are used to determine the sizes of spatial inhomogeneities (?holes?) in cumulus clouds. The majority of holes are found near cloud edges, ...

Abstract: This paper describes results of two penetrations of a moderate intensity storm made by an armored T-28 aircraft on 22 July 1972 as a participant in the National Hail Research Experiment. The penetrations showed multiple ...

Abstract: Precipitation particle sizes were measured using a continuous hydrometeor sampler (foil impactor) during penetrations of hailstorms with an armored T-28 aircraft. Data have been analyzed from three penetrations of a storm ...

Abstract: A model of an evolving hailstorm is synthesized from data presented in four related papers in this issue. The storm model, which is applicable to a class of ordinary multicell hailstorms and similar to earlier models derived ...
