Ocean Modeling Discussion

Hi,All,

In ROMS CDL file: frc_rivers.cdl, there are lines defined at river_time:
river_time: units="days since 1992-01-01 00:00:00";
river_time: add_offset = 2448623.

Can someone explain the meaning of "2448623"? Thanks.

Thanks, Alazhar,

The grid input file can be correctly applied to ROMS version 3.0. I run version 3.0 using the same grid input file and it gets:

Maximum grid stiffness ratios: rx0 = 5.664869E-01 (Beckmann and Haidvogel)
rx1 = 1.730999E+01 (Haney)


Initial basin volumes: TotVolume = 4 ...

Hi, All,

I am using latest version of ROMS to run a case with one boundary (south). The initial conditions are 0 for seal level and velocities and climatological data for TS. The external forces include winds, heat fluxes, and rivers. Along the open boundary, the boundary file provides the sea ...

Hi, Kate,

Ok, in my case, I don't define vertical random walk. At the input file of the float trajectory, we provide initial locations of real depth (meter) below the surface in vertical. I am not sure at ROMS float trajectory subroutine, it first converts this depth to s-coordinate then using ...

Kate,

Thanks for your reply. I check the step_floats.F. First I want to find where the variable "FLOAT_VWALK" (vertical random walk) is defined, but I can't find it in all ROMS3.0 package. Do you know where the variable "FLOAT_VWALK" is defined? Thanks!

Hello all,

I am running ROMS particle trajectory. The particles are initially released near the bottom and I would like to limit particles move without change of sigma-coordinater. From the input file, the option "T" is used to controlled float trajectory type. When T=1, it is neutral density 3D ...
