Improved Indian Ocean dipole seasonal prediction in the new generation of CMA prediction system

Geoscience Letters, 2023
Seasonal prediction of the Indian Ocean dipole (IOD) is important, considering its impact on the climate of surrounding regions. Here we compare the prediction of the IOD in two generations of prediction system developed by the China Meteorology ...

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

The prediction skill of Indian Ocean dipole mode in DCPP-CMIP6 decadal hindcast models

Environmental Research Communications
The Indian Ocean dipole (IOD) mode events are one of the most fascinating interannual ocean-atmosphere phenomenon in the tropical Indian Ocean. The zonal contrast of tropical ocean conditions foists enormous unfavorable impacts on the regional weather ...

The increased frequency of combined El Niño and positive IOD events since 1965s and its impacts on maritime continent hydroclimates

Scientific Reports, 2022
The Indian and Pacific Oceans surround the Maritime Continent (MC). Major modes of sea surface temperature variability in both oceans, including the Indian Ocean Dipole (IOD) and El Niño–Southern Oscillation (ENSO), can strongly affect precipitation on ...

Rapid Global Oxygen Shifts and Delayed OMZ Response: Pulse and Memory of the Pacific Decadal Oscillation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Natural decadal variability often obscures anthropogenic trends in ocean deoxygenation. Using a global observational oxygen reconstruction (1965–2022), we investigate the role of the Pacific Decadal Oscillation (PDO) in modulating decadal oxygen variability.

Indian Ocean Dipole and El Niño/Southern Oscillation impacts on regional chlorophyll anomalies in the Indian Ocean [PDF]

Biogeosciences, 2013
The Indian Ocean Dipole (IOD) and the El Niño/Southern Oscillation (ENSO) are independent climate modes, which frequently co-occur, driving significant interannual changes within the Indian Ocean.

Subsurface‐Intensified Marine Heatwaves: A Hidden and Intense Warming Threat to Tropical Ocean Ecosystems

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Understanding how the vertical structure of marine heatwaves (MHWs) influences ecosystems remains limited. Here we investigated subsurface‐intensified (Type‐1) and surface (Type‐2) MHWs in tropical oceans using reanalysis data sets. Type‐1 MHWs occur most frequently and are concentrated near the equator, with a threefold greater median ...

Improved Predictability of the Indian Ocean Dipole Using Seasonally Modulated ENSO Forcing Forecasts

Geophysical Research Letters, 2019
Despite recent progress in seasonal forecast systems, the predictive skill for the Indian Ocean Dipole (IOD) remains typically limited to a lead time of one season or less in both dynamical and empirical models.

Role of Extreme Indian Ocean Dipole in Regulating Three‐Dimensional Freshwater Content in the Southeast Indian Ocean

Geophysical Research Letters, 2023
The tropical Southeast Indian Ocean (SEIO) is a key area linking the global freshwater and heat exchanges. The Indian Ocean Dipole (IOD) fundamentally modulates the Indian Ocean circulation and thus regulates the basin‐wide freshwater balance.

The Impact of ENSO on Euro‐Atlantic Circulation a Year Later via Long‐Lived Tropical SST Anomalies

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The second winter response to ENSO in the Euro‐Atlantic sector is a surprising recent discovery, however, the underlying mechanisms remain uncertain and are challenging to determine from observations. Here we revisit the second winter response to ENSO using multiple large ensemble climate model simulations to examine its robustness and ...
