英文摘要	Combining the dynamical surface-trapped mode derived from the Surface Quasi-Geostrophic (SQG) function with the statistical mode calculated from multivariate empirical orthogonal function (EOF) reconstruction (mEOF-R) method, this paper proposes a new method, SQG-mEOF-R, to estimate the interior density from the sea surface density and sea surface height. This method is applied to the eddy-resolving Ocean General Circulation Model For the Earth simulator simulation and compared with the conventional SQG, isQG (interior plus SQG), and mEOF-R methods. Two different dynamical regimes were considered: the NorthWest Pacific, dominated by surface-intensified eddies, and the Southeast Pacific, characterized by the occurrence of subsurface-intensified eddies. In both regions, the proposed method proves to be robust in reconstructing mesoscale features, with reduced root-mean square error and relatively high correlation coefficient. The superiority of SQG-mEOF-R is highlighted in those subsurface-intensified eddies that are little or nothing reconstructed by SQG or isQG method. © 2020. American Geophysical Union.
