What are the drivers of sea surface temperature and sea surface salinity interannual variability in the Java coast upwelling region?

Overview

• Identify the drivers of interannual variability in the coastal upwelling region south of Java in the Eastern Indian Ocean.

Conclusions

• Observed interannual variability in salinity and temperature is well reproduced in ECCO v4r4.
• Explained variance in temperature is dominated by heat flux and winds; explained variance in salinity is dominated by freshwater flux and winds.
• Adjoint tracer simulations find more tracer originating northwest in the Indian Ocean in 2010 than in 1994.
