Jdog.naar: Description of the turbulent diffusion scheme in the Mars PCM
2023-02-13T15:47:36Z
<p>Description of the turbulent diffusion scheme in the Mars PCM</p>
<p><b>New page</b></p><div>== Overview of the vdifc routine ==<br />
<br />
Vdifc is a Fortran routine used to compute the turbulent diffusion for the temperature, the wind (U and V, horizontal wind only) and all tracers. It works in a implicit fashion as it actually solves the following equation :<br />
<br />
x(t+1) = x(t) + dt * (dx/dt)phys(t) + dt * (dx/dt)difv(t+1)<br />
<br />
Authorship : Hourdin/Forget/Fournier<br />
<br />
== Naming convention of the variables ==<br />
<br />
As this routine is very ancient, it has been written using the old convention for variables. At first sight they seem hard to read but their nomenclature is very straightforward :<br />
<br />
- All variables coming from an upper-level subroutine are preceded by the letter "p". This includes output variables in vdifc like "pdudif(ngrid,nlay),pdvdif(ngrid,nlay),pdqdif(ngrid,nlay,nq),pdqsdif(ngrid,nq)" and others.<br />
- All local variables are preceded by the letter "z". Those are variables used specifically in vdifc_mod, such as "ztrsf" for the treatment of surface water ice, or "za, zb, zc, zq1temp" for the implicit scheme.<br />
- The routine computes tendencies which are later added to the physical variables outside of vdifc_mod, in physiq_mod.F. The tendency variables are named with the suffix "dif" such as "pdudif(ngrid,nlay), dwatercap_dif(ngrid,nlay)". This is specific to vdifc.<br />
<br />
<br />
== Exhaustive inventory of variables used in vdifc_mod.F ==<br />
<br />
Someone do something about za, zb, zc...<br />
