Abstract: Calculation of the trajectories of precipitation particles growing in a simplified thunderstorm updraft model shows some effects that have a bearing on understanding the mechanism of water storage in thunderstorms, the ...

Abstract: The Italian Po Valley hail problem is examined and a description is presented of its economic, dimensions, its climatology, and some of the meteorological factors which influence it. A brief history of hail prevention in ...

Abstract: Aerial photographs of crop-hail damage areas have revealed a smaller-scale feature of damage patterns than has previously been reported. These features, called ?hailstripes,? are long, narrow (15?30 m width) stripes of ...

Abstract: Potential ice nuclei, particles which become ice nuclei when properly treated, are produced in automotive exhaust. They are activated by iodine vapor and are believed to be lead particles originating from the tetraethyl ...

Abstract: Surface winds which accompany the fall of hail have a profound effect on crop damage. Quantitative estimates of the horizontal and total flux of hailstone kinetic energy can be made with simple theoretical considerations ...

Abstract: Studies of small-scale variability of hailfall parameters are being pursued using fine-scale networks of passive hail sensors of various designs. These studies have revealed the great variability which exists in objective ...

Abstract: For the past three years, a Learjet has been making microphysical measurements in new cloud development on the flanks of multicellular storms in the eastern Transvaal area of South Africa. Data from an imaging probe and a ...
