Propagation mechanisms for the Madden-Julian Oscillation [PDF]

, 2000
The Madden-Julian Oscillation (MJO) is examined using 20 years of outgoing longwave radiation and NCEP-NCAR reanalysis data. Two mechanisms for the eastward propagation and regeneration of the convective anomalies are suggested.

Madden–Julian Oscillation

Atmosphere, 2018
The Madden–Julian Oscillation (MJO) is the most important mode of tropical intraseasonal variability. [...]

The first observational evidence of a mixed Rossby–gravity wave contribution to triggering the onset process of the South China Sea summer monsoon

Environmental Research Letters, 2023
Convectively coupled equatorial waves (Kelvin waves, equatorial Rossby waves, the Madden–Julian Oscillation, tropical depression–type waves, and mixed Rossby–gravity (MRG) waves) are important components of the tropical atmosphere.

Influence of the Madden-Julian Oscillation on upper tropospheric humidity [PDF]

, 2002
Variations of upper tropospheric humidity (UTH) and cold cloud in the tropics reveal coherent changes that propagate eastward from the Indian Ocean into the Pacific. The coherence of UTH is high at periods of 30–90 days along the equator.

Primary and successive events in the Madden–Julian Oscillation [PDF]

, 2008
Conventional analyses of the MJO tend to produce a repeating cycle, such that any particular feature cannot be unambiguously attributed to the current or previous event.

Modulation of station rainfall over the western Pacific by the Madden-Julian oscillation [PDF]

, 2005
Rainfall data from 140 stations in the PACRAIN network in the tropical western Pacific are analysed to assess the signal due to the Madden-Julian Oscillation (MJO). During northern winter, the station rainfall difference between the wet and dry phases of

Response of the West African Monsoon to the Madden–Julian Oscillation [PDF]

, 2009
Observations show that rainfall over West Africa is influenced by the Madden-Julian Oscillation (MJO). A number of mechanisms have been suggested: 1) forcing by equatorial waves; 2) enhanced monsoon moisture supply; and 3) increased African easterly wave

Intraseasonal to interannual variability of Kelvin wave momentum fluxes as derived from high-resolution radiosonde data [PDF]

Atmospheric Chemistry and Physics, 2017
Observational estimates of Kelvin wave momentum fluxes in the tropical lower stratosphere remain challenging. Here we extend a method based on linear wave theory to estimate daily time series of these momentum fluxes from high-resolution radiosonde ...

Ocean Rossby waves as a triggering mechanism for primary Madden-Julian events [PDF]

, 2012
The Madden–Julian Oscillation (MJO) is sporadic, with episodes of cyclical activity interspersed with inactive periods. However, it remains unclear what may trigger a Madden–Julian (MJ) event which is not immediately preceded by any MJO activity: a ...

Dynamical ocean forcing of the Madden-Julian Oscillation at lead times of up to five months [PDF]

, 2011
We show that a simple three-dimensional ocean model linearised about a resting basic state can accurately simulate the dynamical ocean response to wind forcing by the Madden-Julian Oscillation (MJO).
