Hi David,

sorry for the late answer.

Already some weeks ago, I repeated a decadal simulations for Africa on MISTRAL , which I also performed on BLIZZARD within the MIKLIP project.
I could (and can) not see any stripes in the results.
But I did not use the COSMO _4.8_clm17 version, but a more recent one (4.21_clm2, which is not available via the redmine! I also don’ see them when using COSMO _5.0 or COSMO _5.1).
Of course, I used the Tiedtke scheme in any case.

However, there remain some questions:
- which intel compiler version did you use? I guess, it was intel/16.0. I used an older one: intel/15.0.3. Could be interesting to recompile with intel/15.0.3 and to repeat your run, interesting not only for you and me, but perhaps also for the DKRZ people
- which MPI did you use? Bull or INTEL? I used the BULL MPI, see also my recommendations on Redmine—> CCLM at DKRZ
- did you follow my recommendations?
- which compiler options did you use for your first try?
- did you also try to use COSMO _4.8_clm19? This version is available from Redmine. It would be interesting to see whether the stripes also appear when using this version.
