I am grateful to Ken Brink for numerous readings and many interesting conversations. I am also indebted to committee members Dave Chapman, Glenn Flierl, Steve Lentz, and Joe Pedlosky for suggestions that greatly improved the work. Glenn Flierl provided the two-layer quasigeostrophic code, and the numerical filter was implemented by Audrey Rogerson. Funding for this work was provided by Grants N00014-92-J-1643 and N00014-92-J-1528 from the U.S. Office of Naval Research (Coastal Dynamics code).
