Description 795-799
Present study consist the rain noise analysis during JAL cyclone. Ocean ambient noise time series data were measured in shallow water areas of Bay of Bengal at an ocean depth of 30m using an autonomous ambient noise measuring system consisting of vertical array of hydrophones with a data acquisition system placed in mid water column. Hydrophones were placed at a depth of 15m and the data from the first element in the array (from the sea surface) were used for analysis. The noise data sets pertaining to the rain events during JAL cyclone were taken for the analysis of rain noise and used for estimating the rain fall parameters such as frequency, drop size and number of drops. Validation of the estimated rain fall events has been carried out utilizing data from Indian Metrological Department (IMD) Chennai.
