Estimates of Precipitation Embryo Densities Using Measurements from an Aircraft Radar
Publisher: American Meteorological Society
Abstract: Determination of the habits (ice or water) and therefore the densities of particles whose images are acquired by 2D probes is often an ambiguous process. A Learjet's radar measurements of equivalent reflectivity factors ...
Coalescence Enhancement in large Multicell Storms Caused by the Emissions from a Kraft Paper Mill
Publisher: American Meteorological Society
Abstract: While conducting a randomized seeding experiment, a storm was selected whose microphysical characteristics were so far from what was expected, given the existing thermodynamic environment, that some explanation was needed ...
An Analysis of a Possible Crop Response to Hail Suppression Seeding: The Nelspruit Hail Suppression Project
Publisher: American Meteorological Society
Abstract: A commercial hail suppression program has been in operation at Nelspruit, South Africa (25°S, 31°E) since December 1971. The seeding technique employed has been the ?on-top? method, which consists of dropping silver iodide ...
A Calorimetric Jet Engine Technique for Estimating the Condensed Water Mixing Ratio in Cumulus Clouds for Cloud Physical and Weather Modification Research
Publisher: American Meteorological Society
Abstract: A technique has been developed for deriving estimates of condensed water mixing ratio in cumulus clouds from measurements of potential temperature in the air in the compressor of a jet engine. Condensate that enters the ...
The Development and Testing of an Airborne Droppable Pyrotechnic Flare System for Seeding Alberta Hailstorms
Publisher: American Meteorological Society
Abstract: Many of the severe and persistent hailstorms in Alberta propagate by means of new cloud development on the southern or western flank. A concept is proposed whereby these cumulus towers are seeded with freezing nuclei early ...
A Preliminary Assessment of the Importance of Coalescence in Convective Clouds of the Eastern Transvaal
Publisher: American Meteorological Society
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 ...
Calculations Pertaining to Hygroscopic Seeding with Flares
Publisher: American Meteorological Society
Abstract: Some possible effects of hygroscopic seeding with flares are explored by calculating how such seeding would modify the initial size distribution of cloud droplets and the subsequent evolution of that size distribution by ...
