Short summary

This study examines the observed storm-generated sea-level variations at several Indian coastal locations in the Arabian Sea and the Bay of Bengal and identifies them as storm surges and harbour oscillations. The residual sea levels measured from sea-level stations in AS have been identified as Kelvin-type surges propagating northwards with almost constant amplitude. Multilinear regression analysis using local surface meteorological data is able to account for ~63% of daily mean sea level.
