Hi,

Just to show some recent noisy mlsp fields (red contour, shaded - 10 m. wind speed) from our pre-op Harmonie (Arome 36h1.3, running on 3 hourly IFS boundaries).

Hi Martynas,

sorry I missed your posting yesterday - my RSS feed did not update itself.

I suppose the simple first question is have you tried running the same experiment with a reduced timestep?

Hi,

No, I have not tried yet. (hopefully some time soon)
It's probably the first time when such problem with Harmonie occurred in our domain with default settings (ts=60 etc.) so I posted this for information.
I also suspect that changing the time-step might help.
