Modulation of local wind-waves at Kalpakkam from remote forcing effects of Southern Ocean swells

► Investigate the possible pathway of distant swells to north Indian Ocean. ► Multi-modeling approach to capture influence of swells on local wind-waves. ► Study the role of non-linear wave-wave interaction between distant swells and wind-waves. ► Quantification of the non-linear interaction process and modulation of background swells on local wind-waves off Kalpakkam.
