Ocean Modeling Discussion

Thank you for your reply

It is well-known that non-breaking waves are a significant source of enhancement for eddy viscosity and heat diffusion. However, there is nothing when I search for non-breaking waves inducing mixing in the ROMS-SWAN or COAWST code. So if I want to add non-breaking waves-induced mixing in my simulati...

Kate, thank you so much for your answers. now I got it. Actually, I should read the code carefully.

I am sure that my surface forcing variable sustr have minimum value -1.731250825225399 N.m-2 and maximum value 0.753999437586370 N.m-2,but why did roms read the sustr and present different min and max values ?? svstr , surface net heat flux,surface net freswater flux also have the same problems GET_...

Dear all: I compiled the latest COAWST code for SANDY case , then I got the following error.I am sure that this error is due to the interpolation between different model grids because when all the model grids are equal then this error disappear.

Dear all: Does anyone have similar problem like this : when the sediment modular activated with SED_DENS defined as following: #define SEDIMENT #ifdef SEDIMENT # define SUSPLOAD # undef BEDLOAD_SOULSBY # undef BEDLOAD_MPM # define SED_DENS # define SED_MORPH # undef SED_BIODIFF # define NONCOHESIVE_...

dear all :

I just run WC13/R4DVAR example,but blow-up ,can anyone give me some hints ??thanks

the attachment is the mode output

I see your simulated tidal phase is completely normal, the phase is out of atan2 in matlab and scaled by 180/pi. You just need to add a constant 360 degree to get a positive number. You can look at this paper for comparison: doi:10.1029/2002JC001451

thank you for your reply!

I follow wilkin's instruction to simulate tide only with M2 and S2 constitutes and the tide start time is set to 2000010100 ,then after three months running I use the harm_roms.m code provided by bzhang to analysis the expanded tide forcing file and got the tide_amp and tide_phase. but I don't know ...

dear all : when I define #define AVERAGES_DETIDE and try to write out Aout(idu3dD) == T ! u_detided detided 3D U-velocity Aout(idv3dD) == T ! v_detided detided 3D V-velocity Aout(idu2dD) == T ! ubar_detided detided 2D U-velocity Aout(idv2dD) == T ! vbar_detided detided 2D V-velocity Aout(idFsuD) == ...

thank you all for the reply! yes ,the mode was right till at the time step 7200 when average file would be created then got the error! if USE_DEBUG=on then it seems everything is ok! it is most likely that the problem has something to do with this issue https://www.myroms.org/forum/viewtopic.php?f=1...

if #undef AVERAGES then the model running is ok ! but #define AVERAGES will get the same error once again! so what's problem?

dear all:
after one month running ,the mode got the following error. I search for all the posts of this website but got nothing .
so could you help me ?

I try to run a example of coawst when I followed the manual's steps to run JOE_TCs AND type ./coawst.bash -j 8 I got following errors，who can help me? /usr/lib/mpich2/bin/mpif90 -frepack-arrays -O3 -ffast-math -I/usr/local/include -I/usr/local/include ./Build/roms_import.o ./Build/propagator.o ./Bui...

could you tell me how to correct it? v3dbc_im.f90:166.8: vg(i,j,k,nstp)=v(i,j,k,nstp)-BOUNDARY(ng)%v_south(i,k) 1 Error: Unclassifiable statement at (1) v3dbc_im.f90:167.3: vg(i,j,k,nout)=v(i,j,k,nout)-BOUNDARY(ng)%v_south(i,k) 1 Error: Unclassifiable statement at (1) make: *** [/home/wrh/model/proj...

yes now the model is ok ! thank you for your reply!

when I run the latest version of roms ,I had the following problem:
oceanO: string.c:177: NC_check_name: Assertion `name != ((void *)0)' failed.
could you tell me what's wrong? thank you!

maybe you should #define masking in your *.h file
good luck!

thank you ! I got it

hi everyone! I am a newer to roms ,now I am making the forcing file by using NCEP every 6 hours data and by using soda every month mean data to form my boundary forcing condition.but when runing the model ,each model time step need forcing data ,so do i need to specify each time step forcing data or...
