Sub-seasonal impact of El Niño–Southern Oscillation on development of the Indian Ocean Dipole

Communications Earth & Environment
The Indian Ocean Dipole exhibits large variations in its evolution depending on the presence of El Niño, with notable changes in intensity, duration, and peak phase. Here, using a simple Indian Ocean Dipole model and observational-reanalysis datasets, we

Indian Ocean Dipole intensifies Benguela Niño through Congo River discharge

Communications Earth & Environment
Benguela Niños are episodes of unusual El Niño-like warming in the upwelling zone off the coast of southwest Africa, with consequential impacts on marine ecosystems, coastal fisheries and regional weather. The strongest Benguela Niño in the past 40 years

Re-emergence of Indian Ocean Equatorial undercurrent under early positive Indian Ocean Dipole

Communications Earth & Environment
The re-emergence of swift and transient Equatorial Undercurrent in the Indian Ocean significantly redistributes mass and heat across the basin, exacerbating large uncertainties in regional climate projections.

The Indian Ocean Dipole Modulates the Phytoplankton Size Structure in the Southern Tropical Indian Ocean

Remote Sensing
The phytoplankton size structure exerts a significant influence on ecological processes and biogeochemical cycles. In this study, the interannual variations in remotely sensed phytoplankton size structure in the southern Tropical Indian Ocean (TIO) and the underlying physical mechanisms were investigated.

Influence of internal climate variability on Indian Ocean Dipole properties. [PDF]

Sci Rep, 2018
The Indian Ocean Dipole (IOD) is the dominant mode of interannual variability over the tropical Indian Ocean (IO) and its future changes are projected to impact the climate and weather of Australia, East Africa, and Indonesia.

Indian Ocean Dipole: Processes and impacts

, 2009
Equatorial Indian Ocean is warmer in the east, has a deeper thermocline and mixed layer, and supports a more convective atmosphere than in the west. During certain years, the eastern Indian Ocean becomes unusually cold, anomalous winds blow from east to west along the equator and southeastward off the coast of Sumatra, thermocline and mixed layer lift ...

Indian Ocean variability changes in the Paleoclimate Modelling Intercomparison Project [PDF]

Climate of the Past, 2023
The Indian Ocean exhibits multiple modes of interannual climate variability, whose future behaviour is uncertain. Recent analysis of glacial climates has uncovered an additional El Niño-like equatorial mode in the Indian Ocean, which could also emerge in

A change in the relation between the Subtropical Indian Ocean Dipole and the South Atlantic Ocean Dipole indices in the past four decades [PDF]

Atmospheric Chemistry and Physics, 2023
We utilized the global atmospheric reanalysis ERA5 and reconstructed sea surface temperature (SST) data from 1979 through 2020 to examine the stability of the relationship between the SST oscillations in the southern Indian Ocean and the Atlantic Ocean ...

Change in Extreme Precipitation Over Indochina Under Climate Change From a Lagrangian Perspective of Water Vapor

Frontiers in Earth Science, 2021
The process of global warming has humidified the atmosphere and increased the occurrence of extreme-precipitation events over the Indochina Peninsula, which lies in the transition region from the South Asian monsoon to the East Asian monsoon.

The mechanism of the formation of the Indian Ocean dipole [PDF]

Monitoring systems of environment, 2021
The purpose of this work is to identify individual cases of the occurrence of a critical layer in the system of zonal currents of the Indian Ocean within certain months for the period 1979-2018 aimed at studying the impact of instability of these currents on the Indian Ocean Dipole (IOD) generation.
