2022年11月16日 · El Niño-Southern Oscillation (ENSO) strongly influences the interannual variations of Madden-Julian Oscillation (MJO)—the dominant mode of tropical intraseasonal variability. Previous studies have revealed more about the impacts of the diversified El Niño on MJO, but less about those of the La Niña diversity.

La Niña driven suppressed convection persisted across the equatorial Central Pacific and southern tier of the United States during the late winter and early spring. However, the suppressed convection at the Date Line recently weakened as the MJO propagated eastward.

2023年12月7日 · We use the daily-mean outgoing longwave radiation MJO index (OMI) as input data to infer bi-dimensional climatological models of the MJO, and analyse the inferred models during El Niño and La...

The MJO was first described in 1971 but a field project held over the west equatorial Pacific during 1992-93 raised awareness of the MJO as a coherent phenomenon, possibly useful for weekly predictions of tropical precipitation and extratropical weather patterns.

2024年9月23日 · Madden-Julian 振荡（ MJO ）是热带大气在季节内尺度（ 20~90 天）上的主要模态，对全球天气和气候系统有着重要影响，并且是延伸期预报的关键可预报性来源。深入理解 MJO 的变异机理，对于提高大气环流模式对 MJO 的模拟能力以及全球延伸期预报具有重要意义。

2021年6月2日 · In this study, we reexamine the effect of two types of El Niño Southern Oscillation (ENSO) modes on Madden Julian Oscillation (MJO) activity in terms of the frequency of MJO phases. Evaluating...

2019年7月31日 · 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.

2022年4月15日 · The MJO convection is stronger over the Indian Ocean during La Niña winters than during El Niño winters. The MJO predictability limit during La Niña winters is enhanced by up to 8 days compared to El Niño winters. The highest (lowest) predictability limit of the MJO is 39 (31) days during La Niña (El Niño) easterly QBO

2022年12月1日 · Using observations and global climate model experiments, this study demonstrates that MJO undergoes distinct variations and Pacific teleconnections when La Niña varies between eastern-Pacific...

2025年3月22日 · La oscilación Madden Julian (MJO, por sus siglas en inglés) es una onda o zona de bajas presiones que recorren todo el mundo en un periodo de 30 a 60 días. Esta onda tiene efectos tanto en el océano como en la atmósfera.
