dc.description.abstractPresent study examines the interannual changes of significant wave height (Hs) in shelf seas around Indian mainland based on the 15-year (1998-2012) wave hindcast data obtained from numerical model. Validation of the hindcast data with buoy-measured data shows that hindcast Hs is reasonably in good agreement with the observation (Pearson correlation coefficient values of 0.92-0.97). Annual average Hs varied from 0.9 to 1.4 m and the wave heights are higher (~20%) in western shelf seas compared to eastern shelf seas. The analysis reveals seasonal fluctuations of wave climate, with a strong influence of Asian summer monsoon in the western shelf seas compared to the eastern shelf seas of India. Maximum Hs varied from 3.65 to 7.36 m and these maximum values were during the tropical cyclones. During 1998 to 2012, a statistically significant positive trend of 0.8-1.4 cm yr-1 in annual mean Hs is observed and the increasing trend is higher ( ~0.7-2.5 cm yr-1) during the Asian summer monsoon period (June-September). The average trend of annual mean wind speed is also positive and is higher (~1.67 cm s 1 yr-1) for the western shelf seas than that for eastern shelf seas (~0.93 cm s 1 yr-1).
