Abstract: A method of measuring drop size distribution in clouds, especially adapted for wind tunnels and other cloud chambers in which the cloud is carried in an air stream, is presented. It consists of photographing the cloud ...

Abstract: Collection efficiencies of drops of radius A less than 120 µm falling through clouds of drop radius a for which the size ratio p=a/A was between 0.18 and 0.23 were found experimentally to be considerably lower than the ...
