## Abstract Iceβcrystal sizeβdistributions have been measured in clouds associated with the intertropical convergence zone and more isolated cumulonimbus clouds in temperate zones. Mean sizeβdistributions fit curves N~D~ = 1,000/D^3^ and N~D~ = 1,000/D^2Β·3^ in tropical and temperate clouds respecti
## Abstract It is shown that iceβcrystal concentrations of order 10/litre may be produced in clouds limited to the β8Β°C level if growing pellets of soft hail release splinters at the rates recently observed in laboratory experiments by Hallett and Mossop (1974) and provided that these splinters can
## Abstract Equations are derived for the growth rate of ice crystals in the form of thin plates and prismatic columns suspended in a supercooled water cloud of given temperature. The effect of the fall motion of the crystal on its development is discussed β in particular a criterion is derived for
