Inverse Estimation of Sea Surface Drag Coefficient Based on Ocean Model or Storm Surge Model

建立了能估计不同风速下海面阻力系数的资料同化模型，并将其应用于实际海况。结果表明，从任意初始参数中可以估计出合理的系数。阐明了即使在观测站没有产生强风的情况下，如果波浪从强风区传播，也可以推导出高风速下的阻力系数。

The data assimilation model that can estimate the appropriate sea surface drag coefficient for each wind speed was developed and was applied to real sea condition. As a result, reasonable coefficients were estimated from the arbitrary initial parameters. Also, it was clarified to be able to deduce drag coefficient in high wind speed if waves were propagated from strong wind region even if the strong wind had not been generated in the observation station.
