Abstract
The efficiency of collecting particles by raindrops and snow flakes, or collectively, hydrometeors, depends on many micromechanisms which drive the aerosol particles to collide with hydrometeors. These micromechanisms include inertial impaction, Brownian motions of aerosol particles, phoretic effects, electric effects, and possibly turbulence. The electric effects on the scavenging of aerosol particles by hydrometeors consist of two kinds, one is due to the net electrostatic charges residing on the aerosol particles and hydrometeors, the other is due to the presence of an external electric field. The paper discusses mathematical models of precipitation scavenging, and experimental verifications. Refs.
