In the ocean surface, there are currents generated by ocean winds. Therefore, ocean wind observation was important to understand the ocean currents. The examination about the technique to estimate ocean wind was performed for a long time by wave data. Various data were included in measured wave data. The swell that a period was big and wave steepness was small. The swell affects the estimation of the ocean wind in previous study.
In this study, ocean winds were estimated by obtained wave height and period from NOWPHAS and SMB method and Toba 3/2-power law. Therefore, wave steepness was lower than 0.02 and a wave with more than 8s of period was the factor that measured value was different from the estimate of ocean wind. The estimation of ocean wind was improved by excluding the wave of the condition mentioned above.
