波浪スペクトルのパラメータ化と船舶レーダー観測値を用いたスペクトル客観解析値の推定

抄録

Wave spectrum analysis was performed using wave forecasted data and observed radar data. Wave spectrum with multiple peaks was estimated effectively by wave spectrum parameterization and data assimilation method corresponding to each peak. By performing optimal interpolation (OI), peak wave period and wave direction approached the radar data without changing the total wave spectrum energy.
