Just crossed the Mississippi above St. L. I sprang for the WIFI and so now I have a clear view of the bottom of the atmosphere out the window and a <a href="https://www.spc.noaa.gov/exper/soundings/help/index.html">skew-t diagram</a> and <a href="https://www.wpc.ncep.noaa.gov/noaa/noaa.gif">weather map</a> of the same on my computer screen. There ought to be SOME relation between them!<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Flying down to Baltimore from Hartford there were scattered to broken clouds arranged in “streets” and quasi streets and proto streets. But the interesting thing was that the streets were arranged with respect to each other all higgledy=piggeldy, even at what appeared to me the same layer. This made me think that the “streeting” of clouds is not, as I had always supposed imposed on a layer by forces extrinsic to that layer, but something that “self organizes” within the layer and that the layer I was looking at was at some critical state with trying to decide which way to street. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Does anybody have anything to say about any of this? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nick <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nicholas S.
