Any further questions? I don't understand several things. BETHEs Firat, I don't under how there can be any doubt about the diffusion law. I t there was only one diffusion law. Well, lets put it this way. Raypt As lorg as you are talking pollecular diffusion then there is only one diffusion 1 However, when you start talking about diffusion of matt different scales of motion in the atmosphere which may anywhere from the molecular scale up to thousands of milen, due to the large scale motions ef the cyclones and antiaycl then you have an entirely different problem of diffusion.| I¢ is intimately tied up with the size of notions which are bpread- jing the clouds. We should be wery technical about thie . always speak of eddy diffusion so that this point dcean'ti bother people. Anything else? If the molecular diffusion wore {rportant it would seem 4 ne BiTr se that you can ealculate the diffusion cocfficient. r" ne Te Bile % _ “Tes aoing .
