Summary: | The past decade has seen an increasing interest in the problem of rainfall from convective clouds. It has been stimulated by the recognition that the mechanism must differ fundamentally from that in layer clouds. Bergeron's (1933) theory, with modifications by Findeisen, is the generally accepted mechanism of precipitation from stratiform clouds. He showed that ice particles can grow rapidly in supersaturated water cloud, then melt and fall as rain. This explanation, which has received rumple experimental confirmation, tended to get carried over to precipitation from convective clouds.
