May 27, 2025 · The Madden–Julian Oscillation (MJO) is the major fluctuation in tropical weather on weekly to monthly timescales. It can be characterised as an eastward moving pulse or wave of cloud and rainfall near the equator that typically recurs every 30 to 60 days.

Mar 11, 2024 · The Madden Julian Oscillation (MJO) influences rainfall patterns in Australia by affecting the location of precipitation, guiding forecast models, and prompting weather warnings in specific regions. By analysing the behaviour of the MJO, forecasters can anticipate shifts in weather patterns and issue timely alerts to regions at risk of flooding ...

Apr 26, 2025 · This study investigates the role of the interaction between the Madden–Julian oscillation (MJO) and local-scale forcings in regulating precipitation and its diurnal variation during the austral summer over coastal areas in northeast (NE) Australia using radar data.

Nov 20, 2024 · The Madden Julian Oscillation and the monsoon should impact Australia in the next fortnight, increasing the risk of heavy rain, flooding, thunderstorms and tropical cyclones in the coming weeks.

May 13, 2025 · Key things to know about the Madden-Julian Oscillation (MJO) The Madden-Julian Oscillation is a key climate driver that effects northern Australia in summer and can be an important moisture source for southern Australia in winter.

Jan 8, 2024 · By the end of December, the intraseasonal MJO completed a circumnavigation of the world in approximately 40 days which is consistent with a canonical MJO. The MJO remains active, with the enhanced phase crossing the Indian Ocean.

Dec 21, 2022 · We assess seasonally varying impacts of the Madden–Julian oscillation (MJO) on Australian maximum and minimum temperature anomalies and extremes, and their modulation by El Niño–Southern Oscillation (ENSO), for the period June 1974–May 2022.

The Madden-Julian Oscillation is a mode of sub-seasonal atmospheric variability that influences the location and strength of tropical precipitation as in this classic schematic below from Rol Madden and Paul Julian.

Nov 20, 2022 · We examine impacts of the Madden–Julian Oscillation (MJO) on Australian springtime temperatures and extremes, explore the mechanisms behind the teleconnections, and assess their prediction in retrospective forecasts using the Bureau of Meteorology’s ACCESS-S1 dynamical forecast system.

Oct 20, 2023 · The Madden-Julian Oscillation (MJO) is a tropical weather pattern that is very important for northern Australia, but can also influence rainfall and temperature patterns across southern Australia.
