Assimilation of GOES rapid-Scan winds into an experimental ETA model during Hurricane Keith
Howard I. Berger, CIMSS/Univ. of Wisconsin, Madison, WI; and C. S. Velden
Experiments designed to optimize the assimilation of winds derived from GOES rapid-scan data into the National Centers for Environmental Prediction's ETA model are being performed. The case study being evaluated is Atlantic Hurricane Keith (Sept/Oct 2000). The wind data are being assimilated into the 48 km ETA model through the ETA Data Assimilation System. It is hoped that the satellite winds will more accurately describe the initial upper-level environment over Hurricane Keith. Various assimilation strategies will be explored in order to optimize the influence of the satellite wind data. Model forecasts of track and intensity will be used to validate the various imposed assimilation strategies. Results will be presented at the meeting.
