Momentum Decoupling Drives Low‐Wind Events During Heatwaves in China: A Hybrid Explainable Machine Learning and Dynamical Modeling Approach

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Compound heatwave and low‐wind (HW‐LW) events increasingly threaten China's energy security. Analysis of 2000–2023 data reveals these compound extremes account for 18.5% of total heatwaves, with their annual frequencies nearly doubling in recent years.

Intensification of the North Pacific Storm Track in the Mid‐1980s: Internal Variability Versus External Forcing

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The mid‐tropospheric winter North Pacific storm track (NPST) underwent an interdecadal transition from weak to strong in the mid‐1980s and exhibited a significant intensification trend. Using climate model outputs, this study investigates the contributions of external forcing and internal variability to the NPST intensification.

Predictability of European winter 2019/20: Indian Ocean dipole impacts on the NAO

Atmospheric Science Letters, 2020
Northern Europe and the UK experienced an exceptionally warm and wet winter in 2019/20, driven by an anomalously positive North Atlantic Oscillation (NAO).

High‐ and Low‐Concentration Spiral Chlorophyll Bands Excited by Vortex Rossby Waves

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract High‐concentration spiral chlorophyll bands (HSCBs) embedded in oceanic mesoscale eddies have recently been observed worldwide. They are considered to be the footprints of vortex Rossby waves (VRWs). Based on satellite observations and drifter data, we identified additional low‐concentration spiral chlorophyll bands (LSCBs).

Weakening Indian Ocean carbon uptake in 2015: The role of amplified basin‐wide warming and reduced Indonesian throughflow

Limnology and Oceanography Letters
In 2015, the Indian Ocean exhibits an exceptionally weakened CO2 uptake, highlighting strong interannual variability of ocean carbon sink. By utilizing multiple ocean CO2 partial pressure (pCO2) data and a state‐of‐the‐art ocean biogeochemical model, we ...

A Unique Feature of the 2019 Extreme Positive Indian Ocean Dipole Event

Geophysical Research Letters, 2020
During austral spring of 2019, an extreme positive Indian Ocean Dipole (pIOD) event occurred, with cold sea surface temperature (SST) anomalies over the eastern equatorial Indian Ocean (EEIO) and warming in the west.

Interannual Variability of Indian High Intensity in Boreal Winter

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract This study investigates the interannual variability of the boreal winter Indian High (WIH) intensity from 1979 to 2023 and explores its causes. Observational results show that WIH intensity peaks at a quasi‐4‐year period with a slight increase over time. The WIH significantly influences temperature and precipitation across the Indian Ocean and

Contributions of Indonesian Throughflow to eastern Indian Ocean surface variability during ENSO events

Atmospheric Science Letters, 2020
The contribution of ocean transport to the transition between the Indian Ocean Dipole mode (IOD) and the Indian Ocean Basin mode (IOB) during El Niño–Southern Oscillation (ENSO) years is investigated using reanalysis products. Composite analysis suggests

Multidecadal Changes in ENSO Drive a Substantial Decline in West Antarctic Sea Ice Predictability

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract ENSO teleconnections are a key source of Antarctic sea‐ice predictability, particularly in the Antarctic Dipole (ADP) region, but whether this predictability remains stable under the recent transition toward Central Pacific (CP) El Niño is unclear.

Global Atmospheric Circulation Reorganization Drives Contrasting Wind Regime Changes Across Hemispheric Latitudes

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Near‐surface wind regimes govern critical Earth system processes including dust mobilization, ocean mixing, and wildfire spread, yet their multi‐decadal evolution under anthropogenic forcing remains poorly constrained. Here we quantify extreme wind frequency changes (1981–2024) using ERA5‐Land reanalysis with a monthly aggregation approach ...
