roms output wrong density anomaly
Hi,
The roms output density anomaly is not consistent with the value I calculated using temp and salt. But the roms output potential vorticity is consistent with value I calculated.

How to decrease nc file bulk using mexnc
Hi,
Using NETCDF4 can obviously decrease nc file bulk.
Is mexnc function able to make it ?
[ncid,status]=mexnc('create',ncname,'clobber');

Re: boundary problem
Dear kate, I'm interested in the vortex coming from the east boundary. The model grid space is 1/10*1/12 and OFES data resolution is 0.1*0.1 and monthly interval. The strong velocity from the west boundary turns into unstable and forms lots of vortex in the interior region. The simulated resoluts co...

Hi, I try to simulate the northwestern pacific region. Near the boundary, the sst appears discontinuous; the ssh appeares a gradient which results virtual velocity along the boundary.

Hi,
I donot understand the S-coordinate parameter hc and Tcline. I use the Transforme 2 equation and find that only hc is used. hc donot need to equal Tcline. What's the role of Tcline.

Re: blow up at first step as long as I turn on the bulk flux
Hi,
ROMS seems only accept the longitude and latitude of monotonous increasing. If you provide the latitude like [30 29 28 27 26 25] instead of [25 26 27 28 29 30], the weird min/max values above appear.

blow up at first step as long as I turn on the bulk flux
Hi,
The atmospheric forcing variables are from NCEP2. As long as I turn on the BULK_FLUXES, it blows up at first step. No nans in the forcing file. However, I tryed the analytical values, it works ok.

Hi Saeed,
I can make some simple programming using python. Do you have the source code generating curvilinear grid? I can follow and try it interactively by Ipython. I will make learning easier. Thank you.

Re: curvilinear orthogonal grid
Thanks kate for your reply,
I checked the orthogonality of my grid, the results is not good.
Should I use curvilinear grid carefully, and just use the land masking?

Hi,
I try to produce a fan-shaped grid with seagrid, but I doubt that the orthogonality of the grid affects the calculation. I'm not sure whether the curvilinear orthogonal grid is proper.

In Linux-ifort.mk file, I didn't set USE_MPI and USE_MPIF90.
I have read the FAQ, but I don't how to set them.
how can I set the USE_MPI, USE_MPIF90 and the FC to its full path.
