Decadal Variability of the Extratropical Response to the Madden–Julian Oscillation

Geophysical Research Letters, 2023
The Madden–Julian Oscillation (MJO) is the leading mode of sub‐seasonal variability in the tropical atmosphere and is a source of predictability for extratropical weather through its teleconnections. MJO teleconnection patterns can be modulated by the El

Projected Earlier Australian Summer Monsoon Onset Associated With Faster Eastward MJO Propagation

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The response of the Australian Summer Monsoon (AUSM) onset to global warming remains a critical and unresolved question. Here, using Coupled Model Intercomparison Project Phase 6 (CMIP6) multi‐model simulations under the SSP5‐8.5 scenario, we project a robust earlier onset by about 5 days by the late 21st century.

Forecasting the Future With Yesterday's Climate: Temperature Bias in AI Weather and Climate Models

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract AI‐based climate and weather models provide fast, skillful forecasts yet face a key challenge: predicting future climates while being trained with historical data. We investigate this issue by analyzing boreal winter land temperature biases in AI weather (FourCastNet V2 Small and Pangu Weather) and climate (Ai2 Climate Emulator version 2 ...

Physics‐Constrained Network for Enhanced Extended‐Range Precipitation Forecasting in East Asia

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The complex summer weather in East Asia poses significant challenges of precipitation forecasting. Despite the promising capabilities of deep learning models in conventional forecasting tasks, their black‐box nature limits physical interpretability.

Distinct Dominant Intraseasonal Oscillation Modes Modulate South China's Persistent Extreme Precipitation in Rainy Season

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract This study investigates mechanisms by which distinct intraseasonal oscillation modes drive regional persistent extreme precipitation events over South China during the rainy season. Based on periodic characteristics of 54 such events, two dominant modes are identified: 12–20‐day (type‐1) and 25–50‐day (type‐2) oscillations. Although comparable

Different Responses of the Madden‐Julian Oscillation to the Fast and Slow Decaying El Niño in Spring

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract This study investigates the modulation of the Madden‐Julian Oscillation (MJO) by El Niño during decaying springs, using reanalysis data. El Niño events are categorized into fast‐decaying (FD) and slow‐decaying (SD) types based on their decaying rate.

Compound North American Cold and European Wind Extremes in ERA5 and CMIP6 Historical and Future Simulations. Part 2: Dynamical Pathways

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Wintertime North American cold spells often co‐occur with European wind extremes, forming so‐called pan‐Atlantic extremes. In Part 1 of this paper, we identified regionally varying relationships between the two sets of extremes in ERA5 reanalysis data.

Maritime continent aerosols reinforce the MJO propagation barrier under El Niño conditions

Environmental Research Letters
The Maritime Continent (MC), a critical region for Madden–Julian oscillation (MJO) propagation, is also a global hotspot for biomass burning aerosol emissions.
