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 ...

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.

The Indian Ocean Dipole

2018
Discovered at the very end of the 20th century, the Indian Ocean Dipole (IOD) is a mode of natural climate variability that arises out of coupled ocean–atmosphere interaction in the Indian Ocean. It is associated with some of the largest changes of ocean–atmosphere state over the equatorial Indian Ocean on interannual time scales.

North Indian Ocean tropical cyclone activities influenced by the Indian Ocean Dipole mode

Science China Earth Sciences, 2012
Using Joint Typhoon Warning Center tropical cyclone (TC) track data over the North Indian Ocean (NIO), National Centers for Environmental Prediction monthly reanalysis wind and outgoing long-wave radiation data, and National Oceanic and Atmospheric Administration sea surface temperature data from 1981 to 2010, spatiotemporal distributions of NIO TC ...

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 ...

Impact of Indian Ocean Dipole on high-frequency atmospheric variability over the Indian Ocean

Atmospheric Research, 2009
A strong relationship between Indian Ocean Dipole (IOD) and high-frequency (HF) atmospheric variability in the low-level zonal wind is reported in the present study. We found that the HF atmospheric variability over the Indian Ocean (IO) is strongly modulated by IOD events, that is, HF atmospheric variability becoming significantly energetic during ...

The Indian Ocean Dipole: A Monopole in SST

Journal of Climate, 2014
Abstract The claim for a zonal-dipole structure in interannual variations of the tropical Indian Ocean (IO) SSTs—the Indian Ocean dipole (IOD)—is reexamined after accounting for El Niño–Southern Oscillation’s (ENSO) influence. The authors seek an a priori accounting of ENSO’s seasonally stratified influence on IO SSTs and evaluate the ...

How is the Indian Ocean Subtropical Dipole excited?

Climate Dynamics, 2012
Based on experiments using a coupled general circulation model which resolves tropical ocean–atmosphere coupled phenomena such as El Nino/Southern Oscillation (ENSO) and the Indian Ocean Dipole, forcing mechanisms of the Indian Ocean subtropical dipole (IOSD) are investigated.

INTERANNUAL OSCILLATORY MODES IN THE INDIAN OCEAN AND PREDICTABILITY OF THE INDIAN OCEAN DIPOLE

2011
This study further investigates the 18-month and 3-year variability modes in the Indian Ocean and their possible use for the prediction of the Indian Ocean dipole (IOD). We argue that the IOD is not an isolated event triggered by a particular ocean–atmosphere state but a continuous oscillatory process, so that the extremely shallow thermocline in ...
