This repo provides the configurations and source codes of MOM6 used to simulate the double-gyre flow.
| File | Purpose |
|---|---|
src/MOM6/config_src/drivers/solo_driver/user_surface_forcing.F90 |
add USER_wind_forcing to define the wind forcing for the double-gyre flow |
src/MOM6/src/user/user_initialization.F90 |
1) modify USER_set_coord to define the reduced gravities between layers; 2) modify USER_initialize_thickness to define the initial layer thicknesses |
src/MOM6/src/core/MOM_continuity_PPM.F90 |
1) add h_relax_user_tilt to apply relaxation to upper layer thickness; 2) add h_mass_cons to enforce mass conservation |
src/MOM6/src/core/MOM.F90 |
add tr_relax_user for relaxation of the online tracer model; it is used in step_mom_tracer_dyn after tracer advection and diffusion |
The top level directory structure groups source code and input files as follow:
| Directory | Purpose |
|---|---|
src/ |
source code for MOM6, SIS2 and FMS-shared code. |
src/MOM6/ |
is a git submodule that contains the source code for MOM6 |
build/ |
contains all the compiled files (.o .mod) and the environment list specific to Cheyenne supercomputer (build/intel/env) |
compile_cheyenne.sh |
shell script to compile the model ( the FMS library and MOM6 in ocean-only mode) |
mom_case/ |
contains all the configuration files for the double-gyre flow |
Based on your platform, modify 1) the environment to be loaded in build/intel/env and 2) the compilation template src/mkmf/templates/cheyenne-intel.mk (this is for Cheyenne).
Run:
sh compile_cheyenne.sh
It will create an ocean executable: build/ocean_only/MOM6.
Copy MOM6 to mom_case/, modify the physical parameters (MOM_input and/or MOM_override) of the model based on the need, and submit the job.
For more details on running the model, see the Getting-started.
