Flag variables relating to cape

Post by Greg Fishel »

If I understand the documentation correctly, if I type CPOS SBSI, I will see a display of CAPE based on a surface based parcel. If I type CPOS MUSI, I will see a display of CAPE based on the most unstable parcel. Why then tonight am I seeing CPOS SBSI values of 1200-1600 over central North Carolina for tomorrow afternoon at 18z, and CPOS MUSI values of 0-100 over the same area at the same time? These displays are using the 00z GFS data from the NOMADS server. Thanks for any help or clarification you can provide.
