Ocean Modeling Discussion

Hi all,

First question:

I am using MATLAB to read output file, 'ocean_his.nc'. If I use small grid numbers such as 100 * 100 *10, it works o.k.. But if I used many grids (not that many I think) such as 500 * 500 * 10, I cannot load output file in MATLAB. If I used 'ncload', it shows like below ...

I think they are the same. When you set the value of dqdt in "ana_sst.h", you need to divide it by (rho0*Cp), and then the unit of dqdt is m/s.

Do I need to divide dQdSST by (rho0*Cp) when I am preparing the forcing file?

In the varinfo.dat:

'dQdSST' ! Input
'surface net heat flux sensitivity ...

In my ana_sst.h
!-----------------------------------------------------------------------
! Set sea surface temperature (Celsius) and heat flux sensitivity to
! SST (Watts/m2).
!-----------------------------------------------------------------------
!
DO j=JstrR,JendR
DO i=IstrR,IendR
sst(i,j ...

I think they are the same. When you set the value of dqdt in "ana_sst.h", you need to divide it by (rho0*Cp), and then the unit of dqdt is m/s.

Hi John,

I wonder why it is not recommended to run ROMS without bottom stress. Thanks.

The variables sustr and svstr are only computed in set_vbc if you have the iceshelf activated. Else, the sustr and svstr are computed in ana_smflux if you have ana_smflux activated, or they are read in ...

The temperatures in all layers increase with time when I have SPLINES undefined. Thanks very much again.

Best,

Thank you so much for your quick responses!

Yes, I activated SPLINES. I will try the experiment without SPLINES.

How are you specifying the surface net heat flux? Are you using an analytical expression in ana_stflux.h ? If so, you ...

Hi all,

I am now using ROMS to do some preliminary tests. I found a problem with vertical diffusion in a very simple experiment.

I started from a simple domain (a cube) with constant temperature and no salinity, nor flow. This is clearly steady and nothing happens. Then I added a constant positive ...
