Two flavors of the Indian Ocean Dipole

Climate Dynamics, 2015
The Indian Ocean Dipole (IOD) is known as a climate mode in the tropical Indian Ocean accompanied by negative (positive) sea surface temperature (SST) anomalies over the eastern (western) pole during its positive phase. However, the western pole of the IOD is not always covered totally by positive SST anomalies.

How does the Indian Ocean subtropical dipole trigger the tropical Indian Ocean dipole via the Mascarene high?

Acta Oceanologica Sinica, 2014
The variation in the Indian Ocean is investigated using Hadley center sea surface temperature (SST) data during the period 1958-2010. All the first empirical orthogonal function (EOF) modes of the SST anomalies (SSTA) in different domains represent the basin-wide warming and are closely related to the Pacific El Nino-Southern Oscillation (ENSO ...

A dipole mode in the tropical Indian Ocean

Nature, 1999
For the tropical Pacific and Atlantic oceans, internal modes of variability that lead to climatic oscillations have been recognized, but in the Indian Ocean region a similar ocean-atmosphere interaction causing interannual climate variability has not yet been found.

A spurious positive Indian Ocean Dipole in 2017

Science Bulletin, 2018
The Indian Ocean Dipole (IOD) is an intrinsic ocean-atmosphere coupled mode in the tropical Indian Ocean (IO). It features a sea surface temperature (SST) anomaly gradient, defined by the dipole mode index (DMI), the difference of area-averaged SSTanomaly between the western tropical IO (50°–70°E, 10°N–10°S) and the southeastern tropical IO (90°–110°E,

A Theory for the Indian Ocean Dipole–Zonal Mode*

Journal of the Atmospheric Sciences, 2003
Abstract Four fundamental differences of air–sea interactions between the tropical Pacific and Indian Oceans are identified based on observational analyses and physical reasoning. The first difference is represented by the strong contrast of a zonal cloud–SST phase relationship between the warm and cool oceans.

Extreme Indian Ocean dipole and rainfall variability over Central Africa

International Journal of Climatology, 2022
Using both observational and reanalysis datasets, this study examines the influence of extreme Indian Ocean Dipole (IOD) events on Central Africa (CA) rainfall from September to December over the period 1980–2016. It is shown that during extreme positive

Oceanic Heat Content as a Predictor of the Indian Ocean Dipole

Journal of Geophysical Research: Oceans, 2022
AbstractIndian Ocean Dipole (IOD) prediction is a challenging problem, largely relying on the relationship between IOD and El Niño‐Southern Oscillation (ENSO). This study demonstrates that heat content internal to the Indian Ocean can be an effective predictor providing extra IOD predictability, through constructing statistical prediction models with ...

Influence of the Indian Ocean Dipole on the Indian Ocean Meridional Heat Transport

Journal of Marine Systems, 2014
Abstract Influence of the Indian Ocean Dipole (IOD) on the Indian Ocean Meridional Heat Transport (MHT) is studied using 60-yr SODA data. Results show that there is anomalous heat transport from the equatorial region to higher latitudes in both hemispheres during IOD events, and the anomalous poleward MHT occurs mainly in the western Indian Ocean ...
