The Madden-Julian Oscillation in NCEP Coupled Model Simulation

Terrestrial, Atmospheric and Oceanic Sciences, 2009
This study documents a detailed analysis on the Madden-Julian Oscillation (MJO) simulated by the National Centers for Environmental Prediction (NCEP) using the Global Forecast System (GFS) model version 2003 coupled with the Climate Forecast System model

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.

A Unified Moisture Mode Framework for Seasonality of the Madden–Julian Oscillation

Journal of Climate, 2017
The Madden–Julian oscillation (MJO) exhibits pronounced seasonality. While it is largely characterized by equatorially eastward propagation during the boreal winter, MJO convection undergoes marked poleward movement over the Asian monsoon region during ...

Madden‐Julian Oscillation and Atmospheric Rivers: New Insights on Water Source and Transport for Extreme Rainfall Over the Western U.S.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Atmospheric rivers (ARs) were first documented by Zhu and Newell for transporting global water vapor. ARs contribute to extreme rainfall, especially over the Western United States. The primary water vapor source of ARs is from the tropical ocean, where convective systems bring the moist flux upward from the surface to the troposphere. Previous

Indo–Western Pacific Tropical Heating Anomalies Regulate the Cross‐Pacific Atmospheric River Highways During Boreal Summer

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Atmospheric rivers (ARs) constitute a global, interconnected highway network rather than isolated regional events. In boreal summer, cross‐Pacific ARs originate over Southeast Asia, are fueled by subtropical outflows from the Asian monsoon plume, transport warm, moist air across the North Pacific, and make landfall in North America (NA).
