The fix is to remove vertical scale factor (e3f/u/v) in the vorticity term. This fix stabilises the model but breacks the kinetic energy conservation (for ENE) and potential enstrophy conservation (for ENS). 2° (UNSTABLE : STICK TO 1° ONLY) In dynldf_lap_blp.F90 when using EEN scheme the e3f used in dynldf is not the one used in dynvor. ==== Proper fix 1° use in ENE and ENS the same definition of e3f scale factor as in EEN. 2° (UNSTABLE : STICK TO 1° ONLY) use the same scale factor in both dynldf and dynvor. This development is to be included in KERNEL-06 action. It changes the results for sette tests using ENE or ENS.
