How to set the boundary in an idealized topography?

[zhaoyun]

Dear all,
I want to set up an idealized upwelling model with shelf shope of 0.001 and wind stress of 0.1. But I confused with the boundary condition. I want to set the western boundary to be land; eastern, northern,southern boundary to be sea. So my boundary defines are as following :
#define NS_PERIODIC
# define WESTERN_WALL
And I don't know how to set the eastern boundary. When I study the upwelling case in ROMS/include files, it just defines EW_PERIODIC, and doesn't deal with the nothern and southern boundary.
Attachments are the model results, but I find the water can't flow out of the eastern boudary, and the high temperature in the surface goes eastward and downwelles in the eastern boudary. I have define: # define SPONGE and # define RADIATION_2D. I don't know why this phenomenan happens. Could any kind person give me some suggestions? Thank you very much!

ROMS no longer has EASTERN_WALL as something it pays attention to. Instead,a wall is the default if no other boundary condition has been set. You need to explicitly tell it to use an open boundary condition. The UPWELLING case ROMS comes with has two walls, upwelling on one, downwelling on the other - this was intentional so as to avoid the open boundary problem.

Try:

Code: Select all

#  define EAST_M2RADIATION
#  define EAST_FSRADIATION
#  define EAST_M3RADIATION
#  define EAST_TRADIATION

The 2D_RADIATION is a modifier on the other radiation options.

Dear Prof. Kate, you are always so kind. After I follow your suggestion, The results seem to be all right. Thanks again.
By the way, I attachs the results.
