Ocean Modeling Discussion

Please join us for a workshop on Regional ocean modeling with MOM6 in the CESM framework
October 13-17, 2025
NSF NCAR Mesa Lab, Boulder CO

This is our first workshop to showcase capabilities, train new users and develop new collaborations for the regional ocean model. The planned agenda will cover ...

Dear colleagues,

NSF NCAR’s Climate and Global Dynamics (CGD) Laboratory is excited to announce the opening of a Project Scientist I position in the Oceanography Section. This position will support the development, evaluation, and scientific use of the Modular Ocean Model version 6 (MOM6) coupled ...

Dear colleagues,

NSF NCAR’s Climate and Global Dynamics (CGD) Laboratory is excited to announce the job opening for a Project Scientist I in their Oceanography Section. This is a two-year position with the possibility of extension. This position primarily supports the Community Earth System Model ...

Hi Aryan,

The following paper gives some guidance, based on the choice of spatial resolution, tracer advection schemes, Reynolds number and turbulence closures, when representing non-hydrostatic processes (lock-exchange and mixed layer instability) using ROMS.

Marques, G., and T. Özgökmen, 2014 ...

Hi Andre,

I suspect there might an inconsistency between the s-coordinate formulation used to create your initial condition and the one used in ROMS. This could lead to horizontal density gradients in your computations.

I don't know why you are using Tcline = 0 and I am not sure if this is fine ...

The following error affects just applications using shallow water equations.

lines 845-848 in inp_par.F (revision 726)

It should be:


IF (LsshCLM(ng).or. &
Lm2CLM (ng).or.LnudgeM2CLM(ng)) THEN
Lclimatology(ng)=.TRUE.
END IF


Cheers,

Gustavo

I believe you made some mistakes when defining 'dye concentration' and 'dye concentration western boundary condition' in varinfo.dat. Try the following instead:


'dye_' ! Input/Output
'dye concentration'
'kilogram meter-3' ! [kg/m3]
'dye_, scalar, series'
'ocean_time'
'idTvar(inert(i ...

Rafael,

The following tutorial (see Section 5.4) explains how to write a curvilinear mesh with data (vectors and scalars) in a VTK file using the visit_writer library: https://wci.llnl.gov/codes/visit/2.0.0/GettingDataIntoVisIt2.0.0.pdf


I read the netcdf file using Python and then I follow the ...

Hi Rich,

I've used Mayavi in the past, but recently I started using Visit ( https://wci.llnl.gov/codes/visit/ ) instead. The latter is also free, high performance, and interacts with Python.

The following tutorial (see Section 5.4) explains how to write a curvilinear mesh with data (vectors and ...
