Application of the smooth orthogonal decomposition to oceanographic data sets
Additional Document Info
The so-called "smooth orthogonal decomposition" technique, developed in the nonlinear vibrations and fatigue community, is applied to an oceanographic data set. This decomposition technique overcomes some limitations of the proper orthogonal decomposition technique by identifying modes which behave smoothly in time and thus being sensitive to both variance amplitude as well as frequency. This important property is demonstrated through identification of a 4 day topographic Rossby wave on the Louisiana slope, which the proper orthogonal decomposition technique fails to isolate. 2014.
