ECCO Analysis of Coastal Upwelling in the Eastern Indian Ocean (ECCO-Up)
Sreelekha Jarugula, Andrew Scherer, Milagro Urricariet

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.
