Abstract

The effect of radiative heat transfer on droplet growth is assessed. It is estimated that radiative cooling is the principal agent of droplet growth in radiation fog, and that supersaturations are very small – slight undersaturation may even occur – and may be relatively unimportant for droplet growth in this environment. Gravitational settling is shown to be the principal limiting factor on droplet growth in radiation fog.

It is also suggested that radiative transfer may have some relevance to the unexpectedly large numbers of 5ΞΌm radius droplets observed in cumulus clouds by Warner (1969).

The collision efficiency of two slightly deformable drops in thermocapillary motion at small Reynolds and Marangoni numbers is determined by a trajectory analysis involving methodology from matched asymptotic expansions. The outer solution for two spherical drops which are nearly touching provides t
