Abstract
A new, fully conserved minimal adjustment scheme with temperature and salinity (T,S) coherency is presented
for eliminating false static instability generated from analyzing and assimilating stable ocean (T, S) profiles data,
that is, from generalized averaging over purely observed data (data analysis) or over modeled/observed data
(data assimilation). This approach consists of a variational method with (a) fully (heat, salt, and potential energy)
conserved conditions, (b) minimal adjustment, and (c) (T,S) coherency. Comparison with three existing schemes
(minimal adjustment, conserved minimal adjustment, and convective adjustment) using observational profiles and a simple one-dimensional ocean mixed layer model shows the superiority of this new scheme.
