Term: **tendency_of_sea_water_salinity_expressed_as_salt_content_due_to_parameterized_eddy_advection**

Unit: kg m-2 s-1

Unit ref:

GRIB:

"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 any parameterized eddy (e.g., submesoscale, mesoscale) advective processes impacting the prognostic salinity.

The phase "tendency_of_X" means derivative of X with respect to time. "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. 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 eddy advection can be represented on various spatial scales and there are standard names for parameterized_mesoscale_eddy_advection and parameterized_submesoscale_eddy_advection which both contribute to the total parameterized eddy advection.

Parameterized eddy advection can be represented on various spatial scales and there are standard names for parameterized_mesoscale_eddy_advection and parameterized_submesoscale_eddy_advection which both contribute 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.
