Abstract: A simple and computationally efficient method is described for estimating hydrometeor size distributions within a convective storm. The method requires air motion measurements (from Doppler radar in this case, but it could ...

Abstract: The principle of formation of etch pits with crystal faces on ice crystals is explained as a natural consequence of evaporation (or any sort of dissolution) at concave surfaces of crystals. A new technique of ice etching ...

Abstract: Examination of the early radar echo histories of several vigorous, cumulus clouds in northeast Colorado and northwest Kansas, with sensitive, dual-polarization radar, reveals the formation of millimeter-sized water drops ...

Abstract: esults are summarized and illustrated from a long series of experiments on ice growth from the vapor, nearly all in a very small range of conditions: ?5°C, slightly below liquid water saturation, with minimal environmental ...

Abstract: The Cooperative Convective Precipitation Experiment, CCOPE, was an outgrowth of the perceived need for more comprehensive data sets on convective clouds. It was planned and executed by a large group of participants, with ...

Abstract: Detailed radar echo structures and histories of two storms are presented. Both advanced into cloudless skies and had prominent, bounded weak echo regions. The storms had comparable size and intensity, and their environments ...

Abstract: It is argued that the mechanism of spongy hailstone growth, in certain conditions, is analogous to growth in conditions of constitutional supercooling. If so, this allows the application of the large body of information ...

Abstract: The application of two-dimensional, surface ?phase? changes to explain activation and memory in heterogeneous ice nucleation is examined and found to contradict nucleation theory. At a temperature at which an ordered surface ...
