Re: Temperature significantly near land areas

Thank you very much for your useful comments. I found above problem was caused by "mask" itself. when I created "grid file" with new version of Matlab (2014a) that problem is gone. I still do not know why it happen because when I check mask value of both "creating by old ver...

Temperature significantly near land areas

Hello I run for real domain in East Sea of Vietnam with resolution of 9 km, 12 vertical layers. + Oceanic variables including temperature, salt, zeta, u and v getting from HYCOM. + All atmospheric variables including 'Uwind','Vwind','Pair','Tair','Qair','rain','swrad','lwrad','bhflux','bwflux','swfl...

Re: How to setup for rotating frame

Question on the float trajectory I ran for modified "lab_canyon" with constant bathymetry of 0.125 (m) in 2D. The angular velocity of rotating frame is 2*pi/25. The flow speed = 0.02 m/s[/b] (as shown in the Figure "zeta_and_velcity_vector.jpg". 1. I released float from location ...

Re: How to setup for rotating frame

Many thanks "Kate" and "Arango" for your very good comments. After setting "define" ana_spinning.h and correcting my plotting code, it is fine now. In addition, original ana_spinning.h lacked a declarations of i and j. Therefore, it gave error during compile. I correcte...

Re: How to setup for rotating frame

Many thanks Kate. It makes sense to me. However, I meet a problem as bellow: I ran for modified "lab_canyon" with constant bathymetry of 0.025 (m) in 2D. + west and east boundary are close ( figure c1 ). + South boundary is inflow ( Flather ) with ( vbar=-0.24m/s,ubar=-0.0022m/s, zeta=0.00...

Re: How to setup for rotating frame

Many thanks. Kate I have one more question that, for "LAB_CAYON" test case, I set "u" & "v" with constant "0.1_r8" for all layers in "ana_initial.h" (as shown in the figure). However, when checking in the "ocean_his.nc" for the first ti...

Re: How to setup for rotating frame

Thank you very much for you good comment. I tested for "LAB_CANYON". It was good. I have an additional question that, where does ana_grid.h get number of grids in x and y direction (in the ocean_his.nc: x_rho=251,y_rho=111)? I could not find any information of "Lm", "Mm"...

How to setup for rotating frame

Dear all I want to do test case for ideal rotating frame (as shown in the figure). The frame rotates counterclockwise. The ideal domain is in circle with land in the middle and open boundary at margin. The current direction is also in counterclockwise I highly appreciate if you can give me any advic...
