Ocean ambient noise off Chennai due to very severe cyclonic storm Vardah

Ocean ambient noise during the passage of a very severe cyclonic storm, Vardah, in the Bay of Bengal has been studied and presented in this paper. A cyclone named Vardah formed near the Andaman and Nicobar Islands on December 6, 2016. The intensified cyclonic storm crossed the south-eastern coast of India in the afternoon hours (local time) of December 12, 2016. During the passage of this cyclone, ocean underwater ambient noise time series data were acquired from the shallow waters of the south-eastern coast of India. In this paper, the noises pertaining to heavy rain and light rain (drizzling) during the cyclonic event have been analysed along with the high wind noise, and the individual power spectra for both the noises have been estimated.
