Modal Interference Drives Madden‐Julian Oscillation Evolution and Predictability

Geophysical Research Letters
A data‐driven dynamical filter is developed to characterize Madden‐Julian Oscillation (MJO) variability, by representing tropical variability with nonorthogonal empirical‐dynamical modes that allow for constructive and destructive interference.

From Rainfall to Rumors: Interpreting the 2024 Bangladesh Floods Through Numbers, Narratives, and Information Gaps

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract When severe floods struck southeastern Bangladesh in August 2024, competing explanations emerged. Meteorological analysis revealed that extreme precipitation was exacerbated by the Madden‐Julian Oscillation and jet stream dynamics. However, alternative narratives proliferated on social media, particularly claims that India deliberately ...

Understanding Interannual Variability of Brahmaputra River Basin Flows Through Bayesian Causal Networks

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Bayesian Causal Networks (BCNs) are adapted to investigate causal factors of hydroclimate variability in the Brahmaputra River Basin (BRB) during the seasonal and sub‐seasonal periods. This is the longest monsoonal river system in India, prone to frequent severe flooding.

The impact of the diurnal cycle on the propagation of Madden‐Julian Oscillation convection across the Maritime Continent

Journal of Advances in Modeling Earth Systems, 2016
Influences of the diurnal cycle on the propagation of the Madden‐Julian Oscillation (MJO) convection across the Maritime Continent (MC) are examined using cloud‐permitting regional model simulations and observations.

The application of the real-time multivariate Madden-Julian Oscillation Index to intraseasonal rainfall forecasting in the mid-latitudes [PDF]

, 2004
The Madden-Julian Oscillation is a tropical atmospheric phenomenon detected as anomalies in zonal winds, convection and cloudiness. This perturbation has a definitive timescale of about thirty to sixty days, allowing its signal to be extracted from ...

Long‐Term Observations Reveal Non‐Negligible Temperature Contributions to Moist Static Energy During the MJO Transition From Suppressed to Active Phases

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The evolution of moist static energy (MSE) is widely used to understand the organization and propagation of the Madden‐Julian Oscillation (MJO). Past studies, largely based on reanalysis or short‐term observations, have highlighted humidity as the dominant driver of MJO evolution.

ENSO Recharge Oscillator Theory Integrating the Southward Wind Shift

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The El Niño–Southern Oscillation (ENSO) is one of the most‐well understood climate phenomena, and the Recharge Oscillator (RO) theory is widely used to conceptualize its physics in observations and models. ENSO‐associated equatorial zonal wind anomalies shift southward in boreal winter, contributing to ENSO termination.

Observed connection between the Madden–Julian oscillation and the upper tropospheric biennial oscillation

Environmental Research Letters
It has been found that the quasi-biennial oscillation (QBO) in the stratosphere have an important impact on the Madden Julian oscillation (MJO). In this study, we show that there is an obvious biennial oscillation in the tropical upper troposphere, which
