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 modeledobserved data data assimilation. This approach consists of a variational method with a fully heat, salt, and potential energy conserved conditions, bminimal 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.
