摘要: The Southwest Monsoon Current (SMC) flows eastward from the Arabian Sea into Bay of Bengal (BoB) during summer, advecting a core high salinity water. This has been linked with High Salinity Water that is presumed to enter BoB directly via SMC. Here we show originates primarily western equatorial Indian Ocean, reaching Somali Current, Equatorial Undercurrent and Years anomalously saline cores are East Africa Coastal winter convergence, an strong Undercurrent. Seasonal reversals occur at SMC junctions act as 'railroad switches' diverting water masses different basins in northern Ocean. Interannual fluctuations wind stress El Nino.
