Abstract: The formation of a warm cloud was studied in a 1.1 m?3, isothermal, slow?expansion cloud chamber. The evolution of the precloud haze droplet population into the incloud haze and cloud droplet populations was measured in ...

Abstract: The cloud gun is a direct-impaction instrument for determining cloud droplet size distributions and number concentrations. The instrument was designed for airborne use. Procedures are detailed for operating the instrument ...

Abstract: A modified version of the Continuous Small Particle Sampler was used to obtain cloud particle samples of the phase change in a cloud chamber. The effects of silver iodide (AgI) and dry ice (CO2) were studied under similar ...

Abstract: A sequence of aerial photographs is presented that illustrates the breakup of a stratus deck that filled the Redwood Creek Valley in northern California on Nov. 4, 1971. The vertical circulation within the valley was deduced ...

Abstract: The flow of moisture through a ?slab? of air, upwind and over the Park Range in northwest Colorado, was estimated from wintertime meteorological measurements. On average, 6?14% of the inflow moisture precipitated onto the ...

Abstract: Observations and measurements were made of supercooled liquid water in clouds which enveloped high elevation sites in the Colorado Rocky Mountains for the winters of 1980/81 through 1983/84. The observations showed that ...

Abstract: A continuous snowfall replicator has been developed using the ?roll-on? Formvar technique to apply a continuous strip of liquid Formvar to a 35-mm motion picture film base. Snow crystals which settle onto the moving strip ...

Abstract: An empirical approximation is presented for estimating the growth of ice crystals by diffusion. The approximation is valid for computing crystal growth under conditions of constant temperature and water saturation. Crystal ...
