BoBBLE-2

Key Processes in BoB
1. Southwest Monsoon Current (SMC) is controlled by both local (wind stress curl) and remote
(equatorial wave propagation) factors.
2. High Salinity Core (HSC) of the SMC has its origins in the western equatorial Indian Ocean,
reaching the BoB via the Somali Current, the Equatorial Undercurrent and the SMC.
3. Seasonal reversals that occur at the Somali Current and SMC junctions act as ‘railroad
switches’ diverting water masses to different basins in the northern Indian Ocean.
