Re: Horizontal diffusion calculation

Thanks for the clarification John.

One more question about the units involved.

The diffusion fluxes have units of m².s⁻¹.°C⁻¹, but to properly add them with the Huon/Hvom_temp variables, which have units of m³.s⁻¹.°C⁻¹, I am missing a meter unit. In this case, what should I do? Should I take ...

Re: Horizontal diffusion calculation

Hi John,

Many thanks for your reply, it was very helpful!

When I calculate the divergence of the temperature gradient, my units are °C·m·s⁻¹, while the temp_hdiff from diagnostics is in °C·s⁻¹. I thought the most correct way to get it right was to divide my calculated horizontal diffusion by Hz ...

Horizontal diffusion calculation

Hi everyone,

I’m working on a cross-shelf heat transport analysis and using Huon_temp/Hvom_temp for the heat fluxes on the grid cell faces. Now, I need to add the horizontal diffusion to get the full heat transport picture.

I know I can calculate it myself, and for my case, it’s the Laplacian ...
