Short summary
In this study, we found that the interannual subsurface temperature and salinity variability of the Bay of Bengal (BoB) shows a remarkable delayed correlation with the Indian Ocean Dipole mode. We employed a regional model and determined the contributions of the coastal Kelvin waves and the westward-moving Rossby waves to this correlation. An analysis of the salinity budget revealed that the advection terms dominate the subsurface salinity changes in the BoB.
