The Madden–Julian oscillation is characterized by an eastward progression of large regions of both enhanced and suppressed tropical rainfall, observed mainly over the Indian and Pacific Ocean.

The Madden-Julian Oscillation is a mode of sub-seasonal atmospheric variability that influences the location and strength of tropical precipitation as in this classic schematic (left) from Rol Madden and Paul Julian.

Dec 31, 2014 · Here we introduce another important player on the tropical stage: the Madden-Julian Oscillation, or MJO. While the MJO is a lesser-known phenomenon, it can have dramatic impacts in the mid-latitudes.

Dynamical models indicate a continued eastward propagation into the Western Pacific but with uncertainty regarding its amplitude. The MJO supports increased chances of tropical cyclone (TC) development across northern Australia and the Coral Sea during weeks 2 and 3.

The Madden-Julian Oscillation is characterised by an eastward spread of large regions of enhanced and suppressed tropical rainfall, mainly observed over the Indian and Pacific Ocean. It was...

Jan 30, 2025 · The Madden-Julian Oscillation (MJO) is known as the dominant mode of tropical intraseasonal variability and has an important role in the coupled-atmosphere system. In 1971 Roland Madden and Paul Julian stumbled upon a 40-50 day oscillation when analyzing zonal wind anomalies in the tropical Pacific.

Jul 31, 2019 · Madden-Julian Oscillation (MJO) is the dominant mode of atmospheric intraseasonal variability and the cornerstone for subseasonal prediction of extreme weather events. Climate modeling and prediction of MJO remain a big challenge, partially due to lack of understanding the MJO diversity.

Madden Julian Oscillation (MJO) I. Definition: The MJO is an intraseasonal fluctuation or “wave” occurring in the global tropics. The MJO is responsible for the majority of weather variability in these regions and results in variations in several important

Dec 18, 2018 · The Madden–Julian oscillation (MJO) produces a region of enhanced precipitation that travels eastwards along the Equator in a 40–50 day cycle, perturbing tropical and high-latitude winds, and...
