Sea roughness is triggered by means of air-sea interface, and at the identical period, it accomplishes a vital function in this interaction. When the wind moves over the ocean, turbulent airflow first incites small waves of centimeter wavelengths (Fig. 6.1 ), that is, centimeter ripples move through friction stresses.
