Abstract: As a basic experiment in warm cloud electrification, evaporating large drops were studied as they floated in an ion-rich environment in a vertical wind tunnel. The drops were found to acquire a positive charge during their ...

Abstract: A vertical wind tunnel using an artificially generated supercooled cloud was constructed to study snowfall processes. It is 18 m high and operates to a temperature as low as ?25°C. Ultrasonic atomizers supply the supercooled ...

Abstract: A best-fit power-law relationship (Z = 427 R1.09) between 1-minute integrated averages of snowfall rate (R) and radar reflectivity factor (Z) was determined on the basis of observations made by using high sensitivity snow ...
