ICE NUCLEATION BY SILVER IODIDE: II. COLLISION EFFICIENCY IN NATURAL CLOUDS

Abstract

An attempt has been made to estimate the contribution of diffusiophoresis to the collision rate between silver iodide nuclei and cloud droplets growing under conditions simulating those in a natural cumulus cloud. Diffusiophoresis is shown to be of no practical importance and consequently certain limitations have been placed on the use of silver iodide as a cloud seeding agent.
