Project Overview

Each hurricane season HFIP will conduct an experiment, referred to as the Demonstration System or Demo System where the program attempts to demonstrate model capability including high resolution ensembles using both regional and global models that go well beyond the current capability of the operational global and regional models for the prediction of hurricanes.

During the 2010 Demonstration, the operational plan is to run a suite of models that were considered Stream 1.5 candidates as determined by the evaluation from the 2010 Retrospective HFIP Testing. Also, a new set of modified or new model configurations are also run as Stream 2 candidates. During the 2010 hurricane season, Stream 1.5 will be limited to regional models with a multi-model ensemble of at least some of the regional models. In 2010, the plan is to extend the experiments of 2009 to more ensemble members, better models and higher resolution, especially for the global models. In addition, the plan is to include additional products from each of the experiments beyond what was provided last year.
