In practical terms, the goal of this project is to translate the work of HG96 into an operational algorithm and to perform sufficient testing to demonstrate the utility of this algorithm by showing that it improves the forecasts of marine storms. To reach this goal we will work towards the following key technical objectives case selection impact study algorithm development and tuning and parallel run. Suitable cases for study will be selected. For each selected case one or more impact experiments will be conducted. These experiments will elucidate the utility of applying the distortion correction within the operational data assimilation cycle, and provide quantitative measures of the improvements in forecast skill in the selected cases. The algorithm will be extended to allow for operational implementation. Tuning of the algorithm will be refined. In addition the algorithm will be made more efficient. Finally, the operational algorithm will undergo pre-implementation testing. This involves running a parallel data assimilation cycle which includes the operational distortion correction algorithm and comparing the resulting forecasts to the corresponding operational forecasts. Parallel runs will be performed using the Navy operational data assimilation and forecast system, with the cooperation of Naval Research Laboratory NRL personnel.
