We study coastal circulation processes and ocean currents along the Indian coast. Their impact is also studied in detail. We use High Frequency (HF) radar data, and process them to obtain high-quality information in temporal and spatial scales.
The seasonally reversing boundary currents along the western Bay of Bengal (BoB) provide a background for studying the rich and complex relationship between tidally-driven currents, mean current structure and mesoscale eddies. A year-long high-resolution surface current data set from high-frequency radars (HFR) during 2015 along the Andhra Pradesh coast (near 82°E, 16°N) has been utilized to investigate the interaction of tidal currents with bathymetry and eddies during three seasons: January, March–April and November–December.

The characteristics of surface currents during November 2016-October 2017 are studied using observations from the high-frequency radars (HFRs) and a moored buoy (BD12) along the western Andaman Sea (WAnS).

This work presents the coastal circulation variability along the Andhra coast in western Bay of Bengal (BoB) using hourly high frequency radar (HFR, 4.4 MHz) derived ocean surface currents during 2015.
