TELLER: Tt le possible for the circulation around a thunderstora to be a complete cycle? It occurs to me that both cases of the late thunderstorsa and the early thunderstorm would perait the rain to bring dom the particles, not on the first way up, but after they had come down and then carried up again. KeLLous Let ne mention again a thing that could occur on sub= sequent thunderstoras. One thunderstorsa lasts about an hour, aod I wouldn't expect the cycle to te complete in en hour, but on an afternoon when thunderstorms may per= sist over an area for many hours the first thunderstora would stir, the next thunderstora would stir even nore, until finally we could, I think, have the debris going back up into a later thunderstorm, I think that is a "ri difficult thing to say anything quantitative about it, except that there is this possibility a How do you reconcile your findings with Dr. Elsenbud's findinza about how much does come out in rainstoras? Let we have Dr. Rapp enswer that. Hay I ask how many and how comson are thunderstoras that go above 30,000 feet. Is this one in « hundred or it is quite a comson thing.?
