| Definition | Diffusivity is also sometimes known as the coefficient of diffusion. Diffusion occurs as a result of a gradient in the spatial distribution of mass concentration, temperature or momentum. The diffusivity may be very different in the vertical and horizontal directions. The construction "vertical_X_diffusivity" means the vertical component of the diffusivity of X due to motion which is not resolved on the grid scale of the model. 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. "Due to background" means caused by a time invariant imposed field which may be either constant over the globe or spatially varying, depending on the ocean model used. | ||
