gfdl uri coupled model
Implemented to operations at NCEP in 2001 after three years of near-real time testing in 1998-2000

Improvements implemented in 2003:

New ocean model domain configurations

Ocean coupling over entire ocean domains

Gulf Stream and Loop Current data assimilation

GFDL/URI Coupled Model

Goal: To better resolve the hurricane core region, especially in major hurricanes

Grid configuration:

1/2o (stationary); 1/6o and 1/12o (movable)

plans for operational implemantion
Plans for Operational Implemantion
  • Ocean coupling in the Eastern Pacific is planned for operational implementation in 2004
  • The high resolution GFDL coupled model will be tested in near real-time in 2004 is planned for operational implementation in 2005
  • The coupled GFDL hurricane-wave-ocean model is being developed
