Greetings! So for more general information on calculations from Univ. of Wyoming, I'd recommend looking at their documentation for the indices: http://weather.uwyo.edu/upperair/indices.html Note that for many of Wyoming's calculations, they are using very specific, sometimes mixed, layers. To your question from Gitter, CAPEV and CINV are the CAPE and CIN, respectively, calculated using the virtual temperature. What makes you believe the virtual temperature from MetPy isn't correct?
