A reduced model of the Madden–Julian oscillation

International Journal for Numerical Methods in Fluids, 2007
AbstractWe have extended our virtual laboratory for internal wave motions (Int. J. Numer. Meth. Fluids 2005; 47:1369–1374) to the case of rotating fluids on an equatorial β‐plane. A virtual wave‐maker is introduced via a time‐dependent coordinate transformation in the meridional direction, represented by two lateral boundary meanders.

Potential Predictability of the Madden–Julian Oscillation

Bulletin of the American Meteorological Society, 2003
The objective of this study is to estimate the limit of dynamical predictability of the Madden–Julian oscillation (MJO). Ensembles of “twin” predictability experiments were carried out with the NASA Goddard Laboratory for the Atmospheres (GLA) atmospheric general circulation model (AGCM) using specified annual cycle SSTs.

Madden–Julian Oscillation in Boreal Winter

2013
In this study, the Madden–Julian Oscillations (MJOs) simulated by FGOALS-g2 and FGOALS-s2 in boreal summer are evaluated using different methodologies: variance maps, wavenumber–frequency spectra, power spectra, and lead–lag correlation. The results demonstrate that both models simulate two individual zones of intra-seasonal variance in both ...

Prediction of the Madden–Julian Oscillation: A Review

Journal of Climate, 2018
AbstractThere has been an accelerating interest in forecasting the weather and climate within the subseasonal time range. The Madden–Julian oscillation (MJO), an organized envelope of tropical convection, is recognized as one of the leading sources of subseasonal predictability.

Lagrangian overturning and the Madden–Julian Oscillation

Quarterly Journal of the Royal Meteorological Society, 2013
AbstractThe Madden–Julian Oscillation (MJO), a planetary‐scale disturbance in zonal winds and equatorial convection that dominates intraseasonal variability in the Tropics, is a challenge to explain and notoriously difficult to simulate with conventional climate models.

The Madden–Julian Oscillation and the Monsoons

2015
The Madden–Julian Oscillation (MJO) is the most important type of tropical intra-seasonal variations in the Earth System and has an influential role on the monsoons. This influence is manifested in many ways, especially on the precipitation variability of the monsoons in Asia, India, Australia–Indonesia, Africa, and the Americas.

Madden-Julian Oscillation: Observations and Mechanisms

2017
In this chapter, the observed features of the Madden–Julian Oscillation (MJO) are first introduced, followed by the discussions of physical mechanisms responsible for the eastward propagation and initiation of MJO. Next the boreal summer intraseasonal oscillation (BSISO) is described, with a special emphasis on the mechanisms responsible for its ...
