Abstract: A sequence of photographs shows waves breaking at an inversion. Partial mixing with air above the cloud layer as breaking occurs increases buoyancy so that the air, while remaining cloudy, does not return to its original ...

Abstract: s a result of recent comprehensive laboratory and field studies, many details have been clarified concerning atmospheric ice crystal habits below ?20°C as a function of temperature, ice supersaturation, air pressure, and ...

Abstract: Measurements of cloud particle properties from aircraft by optical and impact techniques are subject to artifacts following particle breakup prior to detection. The impact kinetic energy to surface energy ratio (L) provides ...

Abstract: A laboratory study of ice crystal growth characteristics at temperatures between ?20° and ?70°C has been performed at ice supersaturations and pressures comparable with those in the atmosphere using a horizontal static ...

Abstract: Observed turbulence and fluctuating microphysical properties of clouds lead the authors to assume that a cloud droplet size distribution results from a large number of random events associated with turbulence and to consider ...

Abstract: The development of precipitation in the top of an isolated maritime cumulus tower is traced by four rapid penetrations with an instrumented aircraft between 400 and 1000 m below the visible top of the growing tower. The ...

Abstract: iquid water content (g m?3), precipitation rate (mm h?1), and radar reflectivity (dBZ) are inferred from cross sections of particle images obtained by aircraft. Each dataset is presented in a probability format to display ...

Abstract: Recent laboratory experiments and in situ observations have produced results in broad agreement with respect to ice crystal habits in the atmosphere. These studies reveal that the ice crystal habit at ?20°C is platelike, ...

Abstract: A survey of reports of electrical activity in hurricanes and typhoons from flight notes and personal experience (18 years, >230 eyewall penetrations for R. A. Black; ?20 years for J. Hallett, plus that of others at the ...

Abstract: The NSF Division of Mesoscale Meteorology and the University of Nevada?Reno (UNR) provided support for a two-week field course at the CSU?CHILL radar during 12?24 May 1991. Ten atmospheric science graduate students and two ...
