The Madden–Julian Oscillation (MJO) is the most dominant mode of subseasonal variability in the tropics, characterized by an eastward-moving band of rain clouds. The MJO modulates the El Niño Southern Oscillation1, tropical cyclones2,3 and the monsoons4–10, and contributes to severe weather events over Asia, Australia, Africa, Europe and the Americas. MJO events travel a distance of 12,000–20,000 km across the tropical oceans, covering a region that has been warming during the twentieth and… 

Recent enhancement and prolonged occurrence of MJO over the Indian Ocean and their impact on Indian summer monsoon rainfall

The Madden–Julian oscillation (MJO) is one of the leading modes of tropical intra-seasonal variability, which exerts significant impacts on the weather and climate across the globe, particularly in

Oceanic Impacts on MJOs Detouring near the Maritime Continent

Madden–Julian oscillations (MJOs) are the dominant mode of intraseasonal variability (ISV) in the atmosphere acting as a bridge between weather and climate. During boreal winter, many MJO events are

Madden–Julian Oscillation-induced extreme rainfalls constrained by global warming mitigation

The sixth assessment report of the IPCC indicates low-to-high confidence in trends of extreme rainfall with regional inconsistency in the tropics, where a key phenomenon causing intra-seasonal

A Secular Shift of the Madden‐Julian Oscillation and Its Relation to Western Pacific Ocean Warming

In the context of global warming, understanding changes in the Madden‐Julian Oscillation (MJO) is of great importance, because of its worldwide impact on surface weather and climate. By analyzing the

Publisher Correction: An oceanic pathway for Madden–Julian Oscillation influence on Maritime Continent Tropical Cyclones

While the Madden–Julian Oscillation (MJO) has been shown to affect tropical cyclones (TCs) worldwide through its modulation of large-scale circulation in the atmosphere, little or no role for the

Recent weakening in MJO-related convective activity over the equatorial Indian Ocean and Maritime Continent

We document the observed changes in the intraseasonal variability of precipitation and outgoing longwave radiation (OLR) associated with the Madden-Julian Oscillation (MJO) from 1998 to 2015 when

Seasonal aridity in the Indo-Pacific Warm Pool during the Late Glacial driven by El Niño-like conditions

Abstract. Island South-East Asia (ISEA) is a highly humid region that hosts the world's largest tropical peat deposits. Most of this peat accumulated only relatively recently during the Holocene,

The Madden‐Julian Oscillation Modulates the Air Quality in the Maritime Continent

Air quality in the Maritime Continent, which worsens particularly during peatland fire periods, causes climate and environmental concerns. The occurrence of peatland fire haze has been related to the

Seasonality and Dynamics of Atmospheric Teleconnection from the Tropical Indian Ocean and the Western Pacific to West Antarctica

The global impact of the tropical Indian Ocean and the Western Pacific (IOWP) is expected to increase in the future because this area has been continuously warming due to global warming; however, the

Zonal‐Scale of the Madden‐Julian Oscillation and Its Propagation Speed on the Interannual Time‐Scale

While no significant long‐term trend in the propagation speed of the Madden‐Julian Oscillation (MJO) in boreal winter is found during the past decades, pronounced year‐to‐year variability of the MJO



Influence of the Madden-Julian Oscillation on East African rainfall. I: Intraseasonal variability and regional dependency

The influence of the Madden–Julian Oscillation (MJO) on rainfall amounts over Equatorial East Africa (Kenya and northern Tanzania) is analysed for the period 1979–95 at the intraseasonal (pentad)

Madden–Julian oscillation changes under anthropogenic warming

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 thereby

Past‐ and present‐day Madden‐Julian Oscillation in CNRM‐CM5

Madden‐Julian Oscillation (MJO) in the past (nineteenth century) and present day (twentieth century) is examined using preindustrial and historical experiments of Centre National de Recherches

Madden–Julian Oscillation: Bridging Weather and Climate

The Madden–Julian oscillation exerts broad influences on global weather and climate as its center of convection moves from the tropical Indian Ocean into the Pacific. Weather events under the

Intraseasonal interaction between the Madden–Julian Oscillation and the North Atlantic Oscillation

Evidence is presented that the main climate intra-seasonal oscillation in the tropics—the Madden–Julian Oscillation—controls part of the distribution and sequences of the four daily weather regimes defined over the North Atlantic–European region in winter.

Slowdown of the Walker circulation driven by tropical Indo-Pacific warming

It is found that SST warming patterns are the main cause of the weakened Walker circulation over the past six decades, and model experiments show that the observed slowdown in the Walker circulation is presumably driven by oceanic rather than atmospheric processes.

The impact of the Madden‐Julian Oscillation trend on the Arctic amplification of surface air temperature during the 1979–2008 boreal winter

One of the most prominent and important features of climate change is that surface air temperature (SAT) change is greatest at high latitudes. The cause for this Arctic amplification of SAT is

Modulation of Eastern North Pacific Hurricanes by the Madden-Julian Oscillation

Abstract Hurricane and tropical storm statistics verify the modulation of eastern Pacific tropical systems by the Madden–Julian oscillation (MJO) as hypothesized by Maloney and Hartmann. Over twice

Seasonal Dependence of the MJO-ENSO Relationship

Abstract Observations of the development of recent El Nino events suggest a pivotal role for the Madden–Julian oscillation (MJO). Previous attempts to uncover a systematic relationship between MJO
