Establishment of Met-ocean Data and Hazard Curves for Wind Energy Areas (WEAs) off the Atlantic Seaboard

Extreme metocean conditions such as surface wind and wave during strong storms play an important role in wind turbines plan, design and construction. This project’s primary goal is to evaluate the historical characteristics of the metocean conditions at seven identified or potential wind energy development areas off the Atlantic seaboard. An atmosphere-ocean-wave coupled numerical model will be used to establish a hindcast database of the metocean conditions at these wind development areas during historical Atlantic tropical cyclones and winter storms that date back to as early as 1851. For recent storms that have adequate observational data the full physics Weather Research Forecast (WRF) model is used to hindcast surface wind. For early tropical cyclones that have only storm center locations and strength available, an empirical relationship is used to derive surface wind field from those track information. The surface wind will then be input   to the ocean and wave model to hindcast the wave conditions. The hindcast surface wind and wave dataset will then be used to create a metocean hazard curve for further analysis and evaluation of the seven wind energy development areas.
