The three‐dimensional model of deep tropical convection described in Miller and Pearce (1974) has been extended by the incorporation of a parametrized ice phase. This parametrization is capable of describing two routes for the formation of precipitation, cloud water → cloud ice→hail and cloud water→rain→ hail, and these are investigated separately, Numerical simulations are then compared with an observational study of two cumulonimbi, one a single‐celled cloud and the other a multi‐celled storm. Special attention is paid to the growth of a daughter cell on one flank.
