BC comments further: Bob, it's more like a Stuve diagram, making it somewhat difficult to see superadiabatic rates. At least for me... -------------------------------------------
I suspect that some readers may not know exactly what BC is saying here, since Stuve diagrams are not widely used today. The top figure shows a skew-T plot of the 00Z 8 September 2008 sounding for Tucson, while the bottom figure shows a Stuve diagram plot of the same sounding. There are at least three superadiabatic layers aloft in the Tucson data - one can be easily seen in the Stuve plot, but the other two are not nearly as obvious as in the skew-T plot.
---------------------------------------------
Thus, one must wonder why the RRS software provides only a Stuve plot. The skew-T plots are what NWS forecasters use in their operational diagnostics and quirks of the data are more evident. Perhaps the private sector contractors who developed RRS software weren't aware of NWS Forecast Office diagnostic procedures?
