Abstract: The mechanism which attributes to Stefan flow around ice crystals (growing by evaporation of supercooled droplets) their high efficiency in scavenging airborne particles is re-examined. The thermophoretic flow toward ...

Abstract: Preliminary results of a chemical analysis of hailstone slice residues are reported. The radial pattern of Fe particles shows a marked outer ring of relatively high concentration. The possible causes are discussed and it ...

Abstract: The inertia of particles is the basis of the present model of particle ?dry deposition? from a turbulent fluid. The basic physical concepts of particle thermal motion as described by Einstein are herein extended to describe ...
