Studying oceanic eddies is important for understanding and predicting ocean circulation and climate variability. The central focus of this dissertation is the energy exchange between eddies and mean ow and banded structures in the low-frequency component of the eddy eld. A combination of a realistic eddy-permitting ocean state estimate and simplied theoretical models is used to address the following speci c questions. (1) What are the major spatial characteristics of eddy-mean ow interaction from an energy perspective? Is eddy-mean ow interaction a local process in most ocean regions? (2) The banded structures in the low-frequency eddy eld are termed striations. How much oceanic variability is associated with striations? How does the time-mean circulation, for example a subtropical gyre or constant mean ow, inuence the origin and characteristics of striations? How much do striations contribute to the energy budget and tracer mixing?
