Both ECMWF and ESSL have an interest in fostering global harmonization of the way CAPE is calculated in different models and also what different types are finally made available for subsequent users – human forecasters being an important group of.

Therefore at the ESSL Testbed we are testing different new approaches this year, alongside of the current operational CAPE and CIN output of ECMWF (with its known limitations).

This week Ivan Tsonevski from ECMWF is present on site at the ESSL Testbed. He stresses that the user feedback collected at the testbed will be very important for decisions on the future selection of operational CAPE and CIN parameters at the ECMWF.
