Winds and associated waves have strong impacts on the physics, chemistry and biology of the coastal and open ocean. Swells are long waves which have been generated by very strong winds, far away from the current location. However, they have high energies and therefore capable of causing detrimental impact on delicate marine operations very far away from where they are generated. The study of swells has always been challenging as even today they are the most poorly predicted part of the sea state. An attempt has been made to account for the effect of swells from southern Indian Ocean to...
