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).

Subseasonal midlatitude prediction skill following Quasi-Biennial Oscillation and Madden–Julian Oscillation activity [PDF]
Weather and Climate Dynamics, 2020 The Madden–Julian Oscillation (MJO) is known to force extratropical weather days to weeks following an MJO event through excitation of stationary Rossby waves, also referred to as tropical–extratropical teleconnections.

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.

The skill of atmospheric linear inverse models in hindcasting the Madden–Julian Oscillation [PDF]
, 2014 A suite of statistical atmosphere-only linear inverse models of varying complexity are used to hindcast recent MJO events from the Year of Tropical Convection and the Cooperative Indian Ocean Experiment on Intraseasonal Variability/Dynamics of the Madden–

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 ...

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

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 ...

Interdecadal variability of intensity of the Madden–Julian oscillation
Atmospheric Science Letters, 2021 The interdecadal variability of intensity of the Madden–Julian oscillation (MJO) during boreal winter was investigated based on two reanalysis datasets (NOAA 20CR and ERA‐20C).

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

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.
