Most of the ocean waves we see by the shore are generated by wind. Ripples are generated when wind blows over the ocean surface, and they gradually grow through absorbing energy from the wind. The huge waves in the ocean can destroy coastal structures and capsize ships, so they have been the subject of study for many years. This article focuses on the genius scientists who developed modern study of ocean waves and clarified the complex property of ocean waves. In addition, I would like to retrace their backgrounds and research results to show the situation of studies during its developing stage.
