Anomalous Walker circulations associated with two flavors of the Indian Ocean Dipole

Geophysical Research Letters, 2016
The Walker circulation is the key component of the atmospheric zonal circulation in the tropics. In this study, it is shown that anomalous Walker circulations associated with two types of the Indian Ocean Dipole (IOD) are remarkably different.

A negative biological Indian Ocean dipole event in 2022. [PDF]

Sci Rep
AbstractThe biological dipole mode index (BDMI) showed a negative biological Indian Ocean dipole (BIOD) event occurred in the Equatorial Indian Ocean with the corresponding BIOD index BDMI(Ratio) at − 0.31 in October 2022. The chlorophyll-a (Chl-a) ratio (or Chl-a anomaly) between Chl-a in October 2022 and October Chl-a climatology from the Visible ...

Can Coastal Upwelling Trigger a Climate Mode? A Study on Intraseasonal‐Scale Coastal Upwelling Off Java and the Indian Ocean Dipole

Geophysical Research Letters, 2022
Coastal upwelling along the southern coast of Java brings cold and nutrient‐rich subsurface water to the surface. We explored whether the upwelling could trigger the onset of the Indian Ocean Dipole (IOD) by supplying cold water to the southeastern ...

Emerging Skill in Multi-Year Prediction of the Indian Ocean Dipole

Frontiers in Climate, 2021
The Indian Ocean Dipole is a leading phenomenon of climate variability in the tropics, which affects the global climate. However, the best lead prediction skill for the Indian Ocean Dipole, until recently, has been limited to ~6 months before the ...

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

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.

The unique mean seasonal cycle in the Indian Ocean anchors its various air-sea coupled modes across the basin

Scientific Reports, 2021
The interannual variability of the sea surface temperature (SST) in the Indian Ocean is complex and characterized by various air-sea coupled modes, which occur around El Niño/La Niña's peak phase (i.e. December–January–February, DJF). Indian Ocean Dipole

Seasonal Evolution of Chlorophyll-a in the North Indian Ocean Associated with the Indian Ocean Dipole and Two Types of El Niño Events

Journal of Marine Science and Engineering, 2022
To investigate the main modes of interannual variation of chlorophyll-a (Chla) with seasonal evolution and its variation cycle in the North Indian Ocean based on satellite-derived products during 1998–2016, a season-reliant empirical orthogonal function (
