I have used CAPE from the GFS model, specifically when crossing the ITCZ. Zygrib includes a box to request the CAPE parameter, but does need internet
access. While sailing, I use airmail2000 to get gribs and more. airmail2000 does not include a checkbox to request the CAPE parameter, but it can be tricked into doing just that: Create a grib request for a selected area, (screenshot 1) and add ",CAPE" to the outgoing email
. or manually craft the request email
The received grib-file does include values for CAPE, and viewfax can display CAPE, see screenshot 2 and 3.
Regarding it's usefulnesss: I can't really say it helped avoiding night-long lightning storms. Learning
more about seasonal weather
and (warm-) current
patterns would have been more helpful.
