Does anyone know how to make this formula work?
I tried making my own, and was able to verify that it works the exact same way as the bundled "derived" formulas, but the results are still strange. I'm just subtracting the Dewpoint (derived) from the Temperature. I keep getting values around -270 so I was thinking there was a problem with the Kelvin conversion, so I added 273 to the formula. My numbers were still off, saying I had depressions of 15 degrees F, where it should have been almost 40 degrees F.
Ideally (in my mind) there would be a way to tell IDV to evaluate the term and ignore units because I can't seem to figure out how the units are meant to come out with parameters. I'm not really seeing that as an option, though. For example, CAPE is no longer 3000 J/Kg, it's just 3000 units. This way I could build up indices like STP that don't care about the units carried over.
