Does the Madden-Julian Oscillation influence aerosol variability? [PDF]

open access: yes, 2008
We investigate the modulation of aerosols by the Madden-Julian Oscillation (MJO) using multiple, global satellite aerosol products: aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) on Nimbus-7, and aerosol optical thickness (AOT) from ...

Atmosphere-ocean coupled processes in the Madden-Julian oscillation [PDF]

open access: yes, 2015
The Madden-Julian oscillation (MJO) is a convectively coupled 30-70 day (intraseasonal) tropical atmospheric mode that drives variations in global weather, but which is poorly simulated in most atmospheric general circulation models.

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.

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 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.

Observed Changes in the Lifetime and Amplitude of the Madden–Julian Oscillation Associated with Interannual ENSO Sea Surface Temperature Anomalies [PDF]

open access: yes, 2007
The Madden-Julian Oscillation (MJO) is analysed using the reanalysis zonal wind and satellite outgoing longwave radiation-based indices of Wheeler and Hendon for the 1974-2005 period.

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 ...

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil

open access: yesInternational Journal of Climatology, EarlyView.
This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Performance Evaluation of the MPAS Model in Simulating Southeast Asian Rainfall Characteristics

open access: yesInternational Journal of Climatology, EarlyView.
This study evaluates the performance of the Model for Prediction Across Scales–Atmosphere (MPAS) in reproducing key rainfall characteristics over Southeast Asia (SEA) during 2000–2020, using the MSWEP dataset as reference. MPAS realistically captures the observed meridional rainfall gradient, with higher rainfall in the south and lower in the north, as

Association of western US compound hydrometeorological extremes with Madden-Julian oscillation and ENSO interaction

open access: yesCommunications Earth & Environment
Extreme weather and climate events can have substantial impacts on society and the environment. Compound extremes (two or more extreme events occurring simultaneously or successively) may exert even larger impacts than individual events.
