This study was supported by the Office of Naval Research (N00014-93-1-0577) through a contract to Harvard University. We are grateful to Drs. Carlos Lozano and Hernan Arango for their helpful discussions on numerical modeling issues. Some helpful discussions with Drs. R. Watts and T. Lee are greatly appreciated. Short- and long-term simulations were carried out at the large-scale supercomputer center at Stennis and at the Pittsburg Supercomputer Center. We would also like to thank Ms. Marsha Cormier, Mr. Wayne G. Leslie, and other members of the Harvard University Oceanography group for their support of this work at numerous instances.
