Modulation of the Westerly and Easterly Quasi-Biennial Oscillation Phases on the Connection between the Madden–Julian Oscillation and the Arctic Oscillation

open access: yesAtmosphere, 2020
Previous studies have revealed the relationship between the Madden−Julian oscillation (MJO) and the Arctic Oscillation (AO). The MJO phase 2/3 is followed by the positive AO phase, and the MJO phase 6/7 is followed by the negative AO phase.

Ocean temperature and salinity components of the Madden-Julian oscillation observed by Argo floats [PDF]

open access: yes, 2010
New diagnostics of the Madden-Julian Oscillation (MJO) cycle in ocean temperature and, for the first time, salinity are presented. The MJO composites are based on 4 years of gridded Argo float data from 2003 to 2006, and extend from the surface to 1,400 ...

Vertical Heating Structures Associated with the MJO as Characterized by TRMM Estimates, ECMWF Reanalyses, and Forecasts: A Case Study during 1998/99 Winter [PDF]

open access: yes, 2009
The Madden–Julian oscillation (MJO) is a fundamental mode of the tropical atmosphere variability that exerts significant influence on global climate and weather systems.

The Madden–Julian Oscillation in CCSM4

open access: yesJournal of Climate, 2011
Abstract This study assesses the ability of the Community Climate System Model, version 4 (CCSM4) to represent the Madden–Julian oscillation (MJO), the dominant mode of intraseasonal variability in the tropical atmosphere. The U.S. Climate Variability and Predictability (CLIVAR) MJO Working Group’s prescribed diagnostic tests are used to

The effect of the Madden-Julian Oscillation on station rainfall and river level in the Fly River system, Papua New Guinea [PDF]

open access: yes, 2013
The Madden-Julian oscillation (MJO) is the dominant mode of intraseasonal variability in tropical rainfall on the large scale, but its signal is often obscured in individual station data, where effects are most directly felt at the local level.

Seasonality in the Madden–Julian Oscillation

open access: yesJournal of Climate, 2004
Abstract This study, using observational data and global reanalysis products, synthesizes existing knowledge on the seasonality in the Madden–Julian oscillation (MJO) and discusses its possible dependence on the mean background state. The seasonality in the MJO is documented in terms of its components in low-level zonal wind and precipitation. A single

Coupled ocean–atmosphere interactions between the Madden–Julian oscillation and synoptic-scale variability over the warm pool [PDF]

open access: yes, 2005
A principal component analysis of the combined fields of sea surface temperature (SST) and surface zonal and meridional wind reveals the dominant mode of intraseasonal (30-70-day) co-variability during northern winter in the tropical Eastern Hemisphere ...

Tropical variability simulated in ICON-A with a spectral cumulus parameterization [PDF]

open access: yes, 2020
We implemented a spectral cumulus parameterization based on a cloud-resolving model (SC scheme) in the icosahedral nonhydrostatic atmospheric model (ICON-A).

Modulation of Polar Low Activity by the Madden‐Julian Oscillation

open access: yesGeophysical Research Letters, 2023
The impacts of the Madden‐Julian Oscillation (MJO) on polar low (PL) activity are examined. We found that PL frequency increases over the Irminger Sea and decreases over the Norwegian‐Barents Seas following the MJO Phases 2–4, and nearly opposite changes

Vertical structure and diabatic processes of the Madden-Julian oscillation [PDF]

open access: yes, 2016
The “Vertical Structure of Diabatic Processes of the Madden-Julian Oscillation” global-model evaluation project developed a novel experimental framework, which produces a complete characterization of models’ abilities to simulate the Madden-Julian ...
