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 that not enough ice fragments are produced when the droplets freeze in free fall but that the numbers of sub‐micron particles ejected during riming may go some way towards explaining the large concentrations of ice crystals in maritime cumulus clouds.
