The wind profiles severely depart from the classical logarithmic profiles, and the deviations increase with the peak wave phase speeds. It is first revealed that the swell-induced perturbations can reach a height of nearly 30 m above the mean sea surface, and these perturbations disturb the overlying airflow under low wind and strong swell conditions. The impact of ocean surface waves on wind stress at the air–sea interface under low to moderate wind conditions was systematically investigated based on a simple constant flux model and flux measurements obtained from two coastal towers in the East China Sea and South China Sea.
