Eastern Indian Ocean warming associated with the negative Indian Ocean dipole: A case study of the 2010 event

摘要: [1] Warm sea surface temperature (SST) anomalies of more than 1 °C occurred in the southeastern tropical Indian Ocean and peaked during August to October 2010. The anomalous SST warming was associated with negative phase dipole (IOD) phenomenon. In this study, observational data from a moored buoy were used together satellite atmospheric reanalysis sets clarify processes that produced anomalously warm We focused on location 5°S, 95°E where situ measurements 10 years by available. observations captured oceanic conditions related event Heat balance analysis demonstrated air-sea heat fluxes horizontal advections mainly account for mixed layer variation. Reduced latent loss had major role producing anomalies. Meridional advection also contributed southeastward current brought warmer water Ocean. present results suggest exchanges play an active IOD. contrast, case cold eastern positive IOD, ocean control These IOD includes different feedback mechanisms its phases.
