Swell and wind-sea partitioning of HF radar directional spectra

Partitioning is a process used to separate wind-sea and swell contributions in an ocean wave directional spectrum simplify, hence make more useful, the interpretation of for users data. HF radar systems can measure over regions coastal from coast 100 km offshore with good spatial temporal resolution depending on operating frequency bandwidth. Such hundreds spectra across field view radar, so there very strong motivation reduce dimensionality data set practical applications using partitioning. For similar reasons partitioning methods are increasingly being model satellite-measured spectra. A method, which extends method Waters J, Wyatt LR, Wolf Hines A. [2013. Data assimilation partitioned into Wavewatch III. Ocean Model. 72:17–31.] data, described, assessed buoy demonstrate variability both wind waves three regions. The results encouraging. could therefore provide useful satellite validations waters where measurements most challenged by wave-current interactions, topography bathymetry.
