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.

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

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 ...

The Role of ENSO Phase Transition in the Delayed North Atlantic Oscillation Response
Abstract The El Niño–Southern Oscillation (ENSO) is the dominant mode of interannual variability in the Earth system, exerting profound influences on global weather and climate. One notable impact is its ability to generate a dipole‐like sea level pressure anomaly pattern over the North Atlantic, resembling the North Atlantic Oscillation (NAO), with El

QBO–TC Relationship in the Western North Pacific Is Nonstationary
Abstract The Quasi‐Biennial Oscillation (QBO) has been proposed as a key factor modulating tropical cyclone (TC) tracks in the western North Pacific, but its robustness remains controversial. This study revisits the QBO–TC relationship by extending the analysis period to 2024.

The Southeast Tropical Indian Ocean (SETIO), dominated by the Indian Ocean monsoon, is an important source region for strong mesoscale eddies. To date, the impacts of the Indian Ocean monsoon on mesoscale eddies have not been clarified. Here we report on

Abstract On 9 December 2025, an atypical synoptic cyclone developed near the borders of Paraguay, Argentina, and southern Brazil, triggering severe weather across south‐southeastern Brazil. Unlike typical South Atlantic extratropical cyclones, which intensify near the coast, this system originated inland and underwent explosive cyclogenesis without a ...

Abstract Declining monsoon rainfall over agriculture‐dependent Eastern Central India (ECI) during 1901–2014 threatens regional food and water security. Observations link ECI drying to rapid Northwest Indian Ocean (NWIO) warming, which weakens monsoon circulation.

Is there an Indian Ocean dipole and is it independent of the El Niño-Southern Oscillation?
The papers by Saji et al (1999) and Webster et al (1999) describe an equatorial Indian Ocean sea surface temperature (SST) dipole pattern (IOD) which they claim modulates rainfall in East Africa and Indonesia, and operates independently of the global ...
