The previous meetings were held in August 2004 - (Bethesda, MD), April 2002 - Louisville, KY, and August 2000 - Madison, WI.

Considerable development and testing of quasi-Lagrangian vertical coordinates has occurred since the last hybrid-&Theta modeling workshop 4 years ago. This work in both the atmospheric and ocean has demonstrated further the potential for isentropic and other quasi-Lagrangian vertical coordinates to improve simulations and forecasts of geophysical fluid flows.

This workshop will include both invited and contributed papers on the latest progress in this rapidly developing field, including papers on principles, design, and research and operational applications and related plans. A poster session may also be included, depending on the number of submissions. Ample time will be set aside for discussion of major theoretical and technical issues. We wish to limit the focus for this workshop to theory, development, and applications for quasi-Lagrangian vertical coordinates.
