Model runs with and without double-diffusive mixing are compared for annual-mean and seasonally varying surface forcing. Sensitivity to different double-diffusive mixing parameterizations is considered. In all cases, the locales and extent of salt fingering (as diagnosed from buoyancy ratio R-p) are grossly comparable to climatology. although fingering in the models tends to be less intense than observed. Double-diffusive mixing leads to relatively minor changes in circulation bur exerts significant regional influences on temperature and salinity.
