Here is the paper about the model. Note that the vector v is the wind velocity vector with components u,v,w and you can see the relationships it has to other variables in equations 3, 4b, and 10. Maybe take a look at figure 2. It might better explain what I mean in the vertical setup of the...

Yes I did switch derivatives only because I am not sure of the role of each variable now. N is definitely a function of both z and ##\theta## but like I said might be able to be consider constant over the domain of the model I am running. The same is true with g, it is also a function of z and...

I am meeting to discuss with my advisor at length this afternoon. N is the Brunt Vaiasala frequency which for the part of the atmosphere I am simulating I think I could say it is a constant or at least approximate it as one. g is acceleration of gravity, so yes the differential equation is...

U and z are not directly related in this model. First there is no z coordinate, ##\theta## is the vertical coordinate that is used. U is the dynamical zonal wind variable. The way to relate U to z is to use the relation above that relates ##\theta## and z

Again apologies for the duplicate post. I was trying to edit my original and thought I removed it but I guess not. Thanks for your help and reply. Ok let me clarify. I need a first order derivative of U wrt to z and performed this transformation which I believe is correct given the relation...

I am running a general circulation model (EPIC, which uses isentropic vertical coordinate system, potential temperature) and need to add vertical diffusion to the zonal velocity U. The vertical coordinate is theta (Θ, potential temperature) and there is no vertical height coordinate in z but I...
