"A velocity is a vector quantity. \"y\" indicates a vector component along the grid y-axis, when this is not true longitude, positive with increasing y. Bolus velocity in an ocean model means the velocity due to a scheme representing eddy-induced effects which are not resolved on the grid scale of the model. bolus_sea_water_y_velocity is used in some parameteris a tions of lateral diffusion in the ocean." .
