## Abstract This paper studies the sensitivity of global ocean analyses to two flow‐dependent formulations of the background‐error standard deviations (σ^b^) for temperature and salinity in a three‐dimensional variational data assimilation (3D‐Var) system. The first formulation is based on an empir
