"Content" indicates a quantity per unit area. The specification of a physical process by the phrase due_to_process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "tendency_of_X" means derivative of X with respect to time. This tendency expresses the time change in model salt content in a grid cell due to parameterized submesoscale eddy advective processes impacting the prognostic salinity.

Parameterized eddy advection in an ocean model means the part due to a scheme representing parameterized eddy-induced advective effects not included in the resolved model velocity field. Parameterized submesoscale eddy advection occurs on a spatial scale of the order of 1‚ÄČkm horizontally. Reference: James C. McWilliams 2016, Submesoscale currents in the ocean, Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, volume 472, issue 2189. DOI: 10.1098/rspa.2016.0117. There are also standard names for parameterized_mesoscale_eddy_advection which, along with parameterized_submesoscale_eddy_advection, contributes to the total parameterized eddy advection.

There are also standard names for parameterized_mesoscale_eddy_advection which, along with parameterized_submesoscale_eddy_advection, contributes to the total parameterized eddy advection. Additionally, when the parameterized advective process is represented in the model as a skew-diffusion rather than an advection, then the parameterized skew diffusion should be included in this diagnostic. The convergence of a skew-flux is identical (in the continuous formulation) to the convergence of an advective flux, making their tendencies the same.
