Fast and slow Kelvin waves in the Madden-Julian Oscillation of a GCM [PDF]
The structure of the Madden-Julian Oscillation (MJO) in an 1800-day integration of the Hadley Centre Unified Model was analysed, and interpreted within a Kelvin wave framework. The model was forced with constant equinoctial (March) boundary conditions so

Eastward Propagation of Anomalous Indo–Pacific Walker Circulation During ENSO Transition
Abstract By analyzing the zonal mass streamfunction over the equatorial Indo–Pacific region in the period 1979–2024, we found that during the decaying phase of 13 out of 31 El Niño‐Southern Oscillation (ENSO) events, the anomalous Indo–Pacific Walker Circulation (IPWC) propagates steadily eastward across the warm pool. Vertical velocity, precipitation,

Real-time localised forecasting of the Madden-Julian Oscillation using neural network models [PDF]
Existing statistical forecast models of the Madden-Julian Oscillation (MJO) are generally of very low order and predict the evolution of a small number (typically two) of principal components (PCs).

Tracking Pulses of the Madden–Julian Oscillation
An international field campaign aiming at atmospheric and oceanic processes associated with the Madden–Julian oscillation (MJO) was conducted in and around the tropical Indian Ocean during October 2011–March 2012. The objective of the field campaign was to collect observations urgently needed to expedite the progress of understanding the key processes ...

Abstract Moisture variability plays a fundamental role in regulating tropical precipitation; however, the mechanisms that sustain moisture anomalies across different timescales remain unclear. This study examines how moisture anomalies are regulated over the Indo‐Pacific warm pool using the column‐integrated moist static energy (CMSE) budget.

Maritime continent aerosols reinforce the MJO propagation barrier under El Niño conditions
The Maritime Continent (MC), a critical region for Madden–Julian oscillation (MJO) propagation, is also a global hotspot for biomass burning aerosol emissions.

The dynamics of wind-driven intraseasonal variability in the equatorial Indian Ocean [PDF]
This commentary provides a discussion of the concept of `bounded rationality' as it applies to the theses advanced by Lopes (1991) and Evans (1991). Lopes's (1991) assessment of the irrationalist consequences of Tversky and Kahneman's (1974) work on ...

In 2023, the Indochina Peninsula saw record spring heatwaves after a La Niña winter, unlike past events typically following El Niño winters. A “heat dome” pattern drove the extreme high temperatures over the ICP in spring 2023. The heat dome was linked to a Rossby wave train triggered by enhanced convection over the Horn of Africa and the Arabian ...

A census of atmospheric variability from seconds to decades [PDF]
This paper synthesizes and summarizes atmospheric variability on time scales from seconds to decades through a phenomenological census. We focus mainly on unforced variability in the troposphere, stratosphere, and mesosphere.

Mysterious Engine of the Madden‐Julian Oscillation
Understanding the fundamental physics of the Madden‐Julian Oscillation, a phenomenon that occurs over the Indian and Pacific Oceans, remains a challenge in tropical atmospheric research.
