Date of Original Version



A summary of upgrades to the operational GFDL hurricane model for 2003 is presented. The errors of this model are compared to those from other dynamic guidance. The model is found to suffer from a spin down and spin up during the first 12 hours of the forecast, probably due to the inconsistent physics between the current axis-symmetric initialization, and the three dimensional model used in producting the forecast. The development of an improved axisymmetric version of the model with identical moist and boundary layer physics between the two models is also presented.
