Ocean Modeling Discussion

Thanks Kate!

So, if it is not periodic there will always gonna be some along coast change, even for uniform winds? If that's the case then I do have to go with the periodic option.

I haven't try a wall in the shalow side and open in the deep side, I'll short the number of points in the NS ...

Hi Professor Warner,

Thanks for the reply!

I did try periodic OBC for the NS and closed EW and that actually fix the problem. However, the experiment we had in mind was to show the formation of an inner shelf, and surface and bottom ekman layers, and I was expecting at some point far enough ...

Hi ROMS Community,

I am trying to set up an experiment to study upwelling/downwelling response to constant wind on an ideal continental shelf. The experiment is force with uniform surface stress of 0.1 N/m^2 in the alongshore direction, for a homogeneous fluid with constant vertical mixing. The ...

thanks a lot Kate, it seems like a great tool
I will try it

I have another pyroms question, perhaps is more about opendap
I am tying to use pyroms to download hycoms ncoda 1/12 data base on the Palau Exmple script, perhaps my question is silly but I cannot find in Hycoms data server a link to the ...

I am trying to generate a grid using pyroms but I keep getting the mask inverted

I've been using pyroms to generate grids North Caribean region without any problem,
any ideas of what could be wrong?

thanks in advance
Luis Sorinas

Yes, please
That would be great
thanks a lot
best

Hello
I have a similar problem, but my IC temperatures error is bigger(error is about 20 degree Celsius almost in every part of my domain)
I am using Data from HYCOM 1/12 Analysis, from 1-8 jul 2014. I used pyroms to create IC and boundary conditions. Did you find out what the problem could be ...

Dear Wilkin and jivica
thanks four your response
I already fix the problem, I follow the wilkin suggestion and in fact my variables did not have a time attribute, once I created a wind_time attribute for U10 and V10, everything was OK, so thanks both of you very much
jivica very useful the ncdump ...

Dear roms users
I'm trying to force a model application with the output from WRF-ARW, so I prepare the forcing files (U y V wind at 10 meters) but it gives an error related the time variable. I'm using a bulk forcing, with analytical initial conditions and close boundaries in order to test only the ...

hello hpftcb
Well, since the error was related to hraw, i try to find hraw variable but it did not appear
so i created my own hraw based on h

grd.vgrid.hraw=grd.vgrid.h
and then when i try to write the grid with

pyroms.grid.write_ROMS_grid(grd, filename='box.nc')
it works fine, I obtain a grid ...

Hello again, I fix the problem of griddata, it seems that there was an issue regarding netcdf in, when a tried to load data from etopo2 bathimetry the griddata function run out of mrmory, but I run the make_box_grid example with the default data that comes as example with Basemap an it works fine In ...

Dear rdussin
Thanks a lot for your response
I try to use the solution that you gave me but it did not work either, after 15 minutes I run out of memory, I have no idea of what could go wrong, I'm triyng to run make_YELLOW_grd_v1.py , is the same prolem that i encounter using griddata from matpltlib ...

Dear kate
Sorry for the late response but I had a problem with my PC, and had to reinstall the system. I'm currently using ubuntu 14.04 and carefully install pyroms, But again When I try to make a grid I still encounter the same problem regarding griddata (t gives me nothing and then the process is ...

Dear hetland
I have struggle to make a grid with pyroms(from hedstrom), when I try to interpolate the bathimetry using griddata from matplotlib.mlab it gives me nothing and the the process is killed after 15 minutes of a blank screen, I saw how you do your bathimetry interpolation in the previous ...

Dear Roms users:
Is there any way to successfully compile Rect.f to make a grid with Seagrid using mex in matlab 2014a with ubuntu 14.04 system. Because according to what a readed in other posts people are having trouble whith it and instead turning to some version that is only for windows, but that ...

I tried with your recommendation from matplotlib.mlab import griddata and the result after 15 minutes of computing is killed with no other information that could give a hint of what the problem could be
thanks in advance

Dear Kate
I'm trying to create a grid for the west part of Cuba with pyroms, I'm beginning the project now so any realistic(non analytic grid) will be fine, then final purpose is to predict the behavior of sea currents and other oceanographic variables in such region with a relatively high spatial ...

dear kate, i was confused and thought that griddata belongs to scipy instead, so i changed it and I'm using matplotlib.mlab. but it does give anything at all, just a blank screen,
I'm really confused
thanks in advance

Kate i already solve the problem of the batimetry but i got a problem with the function griddata, any advice?
thanks in advance

Dear Kate
i solved my problem with the np.array(sorry, I'm new at python)
but now I found another problem regarding the format of the topography file, does pyroms handle netcdf, because by default the format is zip??
I'm using etopo2 and have the same problem with gebco08
again thanks in advance ...

Dear Kate , i have an lpsolve55.so file in the pyroms-master/../bathy_smoother and also in pyroms-install/../../bathy_smother but whe a run make_grid.py this is what a i get
what can i do?

Kate thank you very much, the change in The __init__.py did not work, but i commented the line and it works just fine( by the way, does this change have any significance)

Regarding the scrip.so, at the end I was linking the file in

Hello, i have been trying to install pyroms for a week and have encounter some problems, mainly with scrip.so, and although at the end I though i solved it, when i try to run and example scrip.so is still missing(the scrip.so exist and is in my PYTHONPATH). I'm working in a 64bit Linux mint 17.3 ...

i will install subversion, but i don't give to much importance because it was a warning
i installed by myself netcdf 4.1.3, with the following options which i need for my WRF project:
--disable-dap --disable-netcdf-4 --disable-shared
thanks very much for replying
