Incorrect computation of Madden-Julian oscillation prediction skill

npj Climate and Atmospheric Science
The Madden–Julian oscillation (MJO) is a major tropical weather system and one of the largest sources of predictability for subseasonal-to-seasonal weather forecasts.

Compound North American Cold and European Wind Extremes in ERA5 and CMIP6 Historical and Future Simulations. Part 2: Dynamical Pathways

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Wintertime North American cold spells often co‐occur with European wind extremes, forming so‐called pan‐Atlantic extremes. In Part 1 of this paper, we identified regionally varying relationships between the two sets of extremes in ERA5 reanalysis data.

Maritime continent aerosols reinforce the MJO propagation barrier under El Niño conditions

Environmental Research Letters
The Maritime Continent (MC), a critical region for Madden–Julian oscillation (MJO) propagation, is also a global hotspot for biomass burning aerosol emissions.

Madden‐Julian Oscillation and Atmospheric Rivers: New Insights on Water Source and Transport for Extreme Rainfall Over the Western U.S.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Atmospheric rivers (ARs) were first documented by Zhu and Newell for transporting global water vapor. ARs contribute to extreme rainfall, especially over the Western United States. The primary water vapor source of ARs is from the tropical ocean, where convective systems bring the moist flux upward from the surface to the troposphere. Previous

The surface diurnal warm layer in the Indian Ocean during CINDY/DYNAMO [PDF]

, 2014
A surface diurnal warm layer is diagnosed from Seaglider observations, and develops on half the days in the CINDY/DYNAMO Indian Ocean experiment. The diurnal warm layer occurs on days of high solar radiation flux (>80 W m-2) and low wind speed (

Indo–Western Pacific Tropical Heating Anomalies Regulate the Cross‐Pacific Atmospheric River Highways During Boreal Summer

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Atmospheric rivers (ARs) constitute a global, interconnected highway network rather than isolated regional events. In boreal summer, cross‐Pacific ARs originate over Southeast Asia, are fueled by subtropical outflows from the Asian monsoon plume, transport warm, moist air across the North Pacific, and make landfall in North America (NA).

Investigation of global lightning and the ionosphere using high frequency induction coils [PDF]

, 2013
In June 2012, the British Geological Survey Geomagnetism team installed two high frequency (100 Hz) induction coil magnetometers at the Eskdalemuir Observatory, in the Scottish Borders of the United Kingdom.

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

, 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.

Simulated Tropical Troposphere Response to the QBO: Effect of Vertical Resolution, Gravity Waves Parameterization, and Boundary Forcing

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract An intermediate complexity general circulation model is used to isolate the effect of vertical resolution and gravity wave parameterization on the simulated monthly quasi‐biennial oscillation (QBO)‐tropical precipitation linkage. For low vertical resolution, the model is able to simulate QBO in the lowermost stratosphere, and its impact on the

A dynamical framework for the origin of the diagonal South Pacific and South Atlantic convergence zones [PDF]

, 2015
The South Pacific Convergence Zone (SPCZ) and South Atlantic Convergence Zone (SACZ) are diagonal bands of precipitation that extend from the equator southeastward into the Southern Hemisphere over the western Pacific and Atlantic Oceans, respectively ...
