Abstract

Estimates for the sedimentation rate of realistic ice crystals at sizes smaller than 100 µm are presented. These calculations, which exploit new results for the capacitance of ice crystals, are compared with laboratory studies and found to be in good agreement. The results highlight a weakness in contemporary ice particle fall speed parametrizations for very small crystals, which can lead to sedimentation rates being overestimated by a factor of two. The theoretical approach applied here may also be useful for calculating the sedimentation rate and mobility of non‐spherical aerosol particles. Copyright © 2008 Royal Meteorological Society

## Abstract In an attempt to explain the excess concentration of ice crystals over ice nuclei in some maritime cumulus clouds, laboratory experiments were carried out to determine whether sub‐micron ice particles are produced when water droplets freeze in free fall or on riming. The results show th
