Mesoscale eddy heat fluxes from observations and a high-resolution model simulation of the Kuroshio Extension

Estimates of divergent eddy heat flux (DEHF) from a high-resolution simulation of the Parallel Ocean Program (POP) are compared with estimates made during the Kuroshio Extension System Study (KESS).  The results from POP are in good agreement with KESS observations.  POP captures the lateral and vertical structure of mean-to-eddy energy conversion rates, which range from 2-10 cm2 s-3. Meridional eddy heat transport values are ~14% larger in POP at its maximum value. This is likely due to the more stable path configuration in POP. The results from this study suggest that POP is a useful tool for estimating eddy statistics in the Kuroshio Extension region, which offers the potential for time series with duration sufficient for statistical convergence and validation of parameterzation schemes for climate models.
