Hurricane relocation system has been implemented in the operational GFS (Global Forecast System) Ensemble Model on August 16, 2005 at NOAA/NCEP. Results show that the hurricane relocation improves the hurricane initialization in GFS ensemble model and significantly reduces the ensemble member track spread. We will discuss the details of the hurricane relocation in GFS ensemble model, and show some test and operational results.
