n1850.ne30_tn14.hybrid_wavparam_fatessp.20241226

[matsbn]

Purpose:
Duplicate set-up of of n1850.ne30_tn14.hybrid_fatessp. 20241204 but with some BLOM modifications:

• Using dev1.6.1.11 tag of BLOM instead of dev1.6.1.8
• Filtering of squared buoyancy frequency and Richardson number for reduced noise in vertical diffusivity.
• Parameterized wave forcing of Langmuir mixing.

---

Description:

To get the code

git clone https://github.com/NorESMhub/NorESM.git
cd NorESM
git checkout noresm2_5_alpha08d

Modify .gitmodules to get BLOM tag dev1.6.1.11 instead of dev1.6.1.8.

./bin/git-fleximod update

NOTE: a memory leak is present in the run and hits agains the node limit when running past 11 years.
