  abstract = {{A}n extremely low salinity anomaly was observed in the {B}ay of {B}engal ({B}o{B}) by various in situ and satellite observations during 2012 spring and ranked as the strongest anomaly in the last two decades. {B}y analyzing various observational and reanalysis datasets, we find that the reversing circulation anomalies caused by a rare co-occurrence of positive {I}ndian {O}cean {D}ipole (p{IOD}) and {L}a {N}ina in 2011 were the main cause of this extreme event. {I}n the fall of 2011, the p{IOD} favored an anticyclonic circulation anomaly flowing from the {B}o{B} into the equatorial {I}ndian {O}cean, whereas the {L}a {N}ina event, which matured in the following winter, sharply reversed the circulation anomaly to a cyclonic pattern. {A}s a result, these reversing circulation anomalies inhibited the southward freshwater transport along the two sides of the {B}o{B} and trapped substantial freshwater to the northern bay by the end of winter. {T}hereafter, the strong seasonal anticyclonic circulation transported this freshwater into the central and southern bay from the northeastern {B}o{B} coastal area, forming the extremely low salinity anomaly during 2012 spring. {T}he key process in forming the extremely low salinity anomaly was the modulation of the seasonal monsoon by interannual processes, specifically the rare combination of p{IOD} and {L}a {N}ina in 2011. {O}ur results highlight the important role of the oceanic circulation in the sea surface salinity ({SSS}) variability in the {B}o{B}. {T}his study provides some new perspectives on the {SSS} interannual variability in the {B}o{B} and the freshwater exchange between the {B}o{B} and {A}rabian {S}ea.},
