WEXLIRs (continued) the only way they could match the temperature minimum obgtrved’ at the ground was by air that must have been brought dows from those heights and then cooled by evaporation, " KELLOOs WEXLER: I want to get this clear - this is outside the thunderstdrs systen, Yesg, it is outside the thunderstorm, I will have to lodk that reference up - this was written in a peper sonetine in ne §30's by someone in the Bydrometeorological Section of the Burdsu ~ and I forgot about it wmtil Lulejian mantioned it. I think that this air entrainment probably is a fact that should be Looked into. KELLOGOs I am sure it does. Oddly enough, this leads directly to my next point, We have been wanting to take up several specific bases that m ght cecur, That is, there are so many variables fh this problen of how debris gets back down to the ground that felt that it was better to fix our ideas by considering some rather explicit and definite cases, The first case we ean diss quickly = that is where we have a surface burst. We havel already discussed this a little bit, end we can say that it depeniis mostly on how we set the weapon off and not on the atmospherie opnditions.. It is determined more by the condition of the ground ani of the ataosphere, However, let's consider a case where we have an air bursth Now, I am making the sseumption tacitly when I talk about an alr burst that here we have small particles that cannot cone to thel ground
