Abstract

A radar study of the streamers of 25 February 1954 at Cambridge, Mass., indicates that horizontal bands of rain are produced by the action of wind shear on the precipitation particles. It is suggested that a “generating layer,” responsible for the streamer formation, consists of a cumuliform cloud configuration within which ice crystals grow rapidly both by sublimation and by riming.
