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.

建立了一个能估算各风速下海面阻力系数的资料同化模型，并将其应用于真实的海况。结果表明，在任意初始参数下，可以得到合理的系数。此外，还阐明了即使在观测站没有产生强风的情况下，如果波浪从强风区域传播，也能够推导出高风速下的阻力系数。
