Madden–Julian Oscillation

open access: yesAtmosphere, 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

open access: yesEnvironmental 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.

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

open access: yes, 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]

open access: yesWeather 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]

open access: yes, 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]

open access: yes, 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]

open access: yesAtmospheric 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]

open access: yes, 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]

open access: yes, 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

open access: yesAtmospheric 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).
