A Reanalysis of the Wolf Creek Pass Cloud Seeding Experiment
Publisher: American Meteorological Society
Abstract: A six-season, randomized-by-season cloud seeding experiment consisting of three seeded seasons and three non-seeded seasons was conducted by Colorado State University (CSU) during the middle and late 1960's in the Wolf ...
Fragmentation of Freezing Drops in Shallow Maritime Frontal Clouds
Publisher: American Meteorological Society
Abstract: Images of frozen drops with pieces missing were collected on two days of airborne sampling in shallow supercooled stratiform frontal clouds in the coastal waters of Washington State. In those limited regions where ice ...
Rapid Development of High Ice Particle Concentrations in Small Polar Maritime Cumuliform Clouds
Publisher: American Meteorological Society
Abstract: Extremely high ice particle concentrations developed rapidly in the ascending tops of maritime cumulus congestus clouds after drizzle drops had already formed below this level by the collision?coalescence mechanism. In one ...
Production of Ice Particles in Clouds Due to Aircraft Penetrations
Publisher: American Meteorological Society
Abstract: Evidence is presented that the passage of an aircraft through supercooled clouds can produce high concentrations of ice particles (> 1000 L?1 at ?8°C in one case). These Aircraft Produced Ice Particles (APIPs) are ...
Further Observations of the Production of Ice Particles in Clouds by Aircraft
Publisher: American Meteorological Society
Abstract: Evidence is presented for the production of high concentrations of rather uniformly-sized ice crystals in a supercooled stratus cloud by a commercial, turbine, propeller-driven aircraft.
A Reevaluation of the Climax Cloud Seeding Experiments Using NOAA Published Data
Publisher: American Meteorological Society
Abstract: Some significant differences exist between the precipitation amounts for Climax 2NW (a station situated near the center of the target area in the Climax I and Climax II cloud seeding experiments) that have been used in ...
Ice Particle Concentrations in Clouds
Publisher: American Meteorological Society
Abstract: Measurements and observations have been made on the development of ice in 90 cumulus (cumulus and cumulonimbus) and 72 stratiform (altocumulus, altostratus, nimbostratus, stratocumulus, and stratus) clouds. Ice particle ...
