Use this thread to point out typographical errors in the ROMS/TOMS user manual.

Hi,

Not a big deal, but the documentation should be correct.
In the v momentum equation, -fu should changed to +fu

In the vertical boundary conditions for z=zeta there should be the total time derivative of zeta for the w condition. If I understand correctly, the advective terms are missing.

Hi,

I was browsing on wikiroms User Guide > Source Code > Functionals section and I think I found a typo regarding ana_hmixcoef.h. It says "For providing analytic atmospheric cloud fraction." in spite of something related to horizontal mixing.

Kind regards,
Rafael

Hi, I found another typo at WikiROMS Functionals section:
ana_nudgcoef.h is defined as: "For providing analytic atmospheric humidity"

Kind Regards,
Rafael

Right you are, thanks!

I guess that there is a typo in P.91 of ROMS Manual.
The "ana_sbflux" in the sixth line from section 7.2.6 (Model forcing) is not in /Functionals.
Should it be "ana_srflux" ?
Best regards, Kai-Cheng, Hu.

You are most likely correct although I don't have the manual with me. Thanks!

The WikiROMS page on open boundary conditions (https://www.myroms.org/wiki/index.php/B ... _condition) appears to have the multiplying gravity terms mixed up between the Flather and Chapman boundary conditions. The Flather boundary condition should have \sqrt{g/h} not \sqrt{gD} and vice versa for Chapman.

I think there is another typo on WikiROMS in the section for horizontal and vertical advection (https://www.myroms.org/wiki/index.php/N ... _Advection). The units don't seem to be working out in the equation for advection of tracer C, or perhaps I am missing something.

At risk of being super annoying, I have another possible typo:

On WikiROMS, under Equations of Motion > Horizontal Boundary Conditions (https://www.myroms.org/wiki/index.php/E ... Conditions), it says

Boundary conditions on these masked regions are straightforward, with a choice of no-slip or free-slip walls.

However, the code in Utilities/metrics.F, when masking is defined for the simulation, says (Line 521)

Set no-slip boundary conditions on land-mask boundaries regardless of supplied value of gamma2.

I'm glad someone is finally reading this.

Perhaps you are missing the fact that u,v still have units of m/s while omega is simply 1/s.

Set no-slip boundary conditions on land-mask boundaries regardless of supplied value of gamma2.

The code here is setting the land mask on psi points, used in:

! Compute flux-components of the horizontal divergence of the stress
! tensor (m5/s2) in XI- and ETA-directions.

It seems that only the outside walls can have free slip or no slip if I understand the code correctly.

I think that the terms are inconsistent regardless of omega's units because the time derivative term has an extra length scale in the denominator. Also, with units of 1/s, the omega term then has two extra length scales in it, relative to the x- and y-derivative terms.

It seems that only the outside walls can have free slip or no slip if I understand the code correctly.

That is my understanding as well. I do think it is then worth noting that masked regions in the interior of numerical domains are always no-slip.

You should know that m is like 1/dx, n is like 1/dy, both having units of 1/m.

You are right. It didn't used to be the case (when I understood what was going on), but Sasha has touched everything.

In the explanation of cppdefs.h in WikiROMS UV_COR links to a page which has the wrong content. What is shown there is actually a copy of the page pointed to by UV_ADV.

[kapitzah]

On page 123 of the user manual right after formula (244) the value of z for sigma=-1 should be -h (not h).

[kapitzah]

In the explanation of variable "Vstretching" the possible (and default) value of 4 is not present.

[kate]

Are you sure you have the 2012 manual?

Are you sure you have the 2012 manual?

OK, my fault. My comment referred to the 2010 manual and not to the draft.

But the issues concerning "Vstretching" and "UV_COR" are still open since they refer to the Wiki. To be more specific here are the pages I refer to:

www.myroms.org/wiki/index.php/Variables#Vstretching
www.myroms.org/wiki/index.php/UV_COR
