| Abstract: | Summary The case study presented here is related to the thermodynamic analysis of entrainment and mixing in a shallow cumuls layer. The fair weather situation on 9. 9. 1983, Voves, is characterized by a field of scattered cumuli of the same depths and by a towering isolated cumulus. The clouds were sampled. Two types of analysis were used, the Paluch analysis and saturation point analysis, both of them making use of conserved parameters and a mixing line structure. Both methods gave similar results. For the small cumuli, lateral entrainment prevailed up to the highest penetration level while in the isolated cumulus, cloud top entrainment was the dominant mixing mechanism.
