[MITgcm-support] advection scheme 33

[Yangxin He]

Hi there,


I am running a simple 2d oceanic model with tides sloshing up and down a slope, so internal tides are generated. Part of my data file looks like


 implicitDiffusion=.TRUE.,

 implicitViscosity=.TRUE.,

#change advection shceme

 tempAdvScheme=33,

 staggerTimeStep=.TRUE.,


The simulation is fine. Two quick questions,

1) I am certainly not an expert in coding, but I think it will be a good idea that I can at least have some idea of what I am using. Where can I find out more information about this advection scheme 33? There does not seem much in the manual.

2) In one of my previous threads here

http://mailman.mitgcm.org/pipermail/mitgcm-support/2019-July/012095.html

Jody mentioned adv33 will allow the lateral diffusion set to 0, i.e. diffKhT=0. I tried it, it did work. But why?


Thanks


Yangxin
