East Florida Shelf Information System (EFSIS)

• Inkweon Bang
• Ocean Prediction Experiment Laboratory
• University of Miami
• at MPCC meeting in January, 2003

5

• Hindcast experiment (1998-2000)
• Coarse (61 ? 31 ? 21) 1030 km
• climatology (Levitus T/S for initial and
  in/outflow bc)
• Eta wind (6 hourly)
• NO heat/salt flux, NO salinity relaxation at the
  surface
• Inflow transport is constant (30 Sv) and the
  distribution along
• the boundary is bell-shaped with a maximum at
  the deepest depth
• High resolution (251 ? 101 ? 25) with same
  forcing as in coarse
• result is not promising

Hardware and Software

• POM (Princeton Ocean Model)
• Compaq Unix Alpha servers
• Downloading data from NDBC buoys, NCEP (Eta), NOS
• C-shell scripts
• Graphics by GMT and switching some to Matlab
• Web server on a PC (will be transferred to Linux
  machine)

Problems We are Facing

• Boundary condition from a larger domain model
• Incorporating tide into baroclinic model
• Making sea level stable inside model domain
• Reliable download of atmospheric forecast data
• Sensitivity study
• Feeding model output to DODS
• Data assimilation of surface current
