The application of the real-time multivariate Madden-Julian Oscillation Index to intraseasonal rainfall forecasting in the mid-latitudes [PDF]

, 2004
The Madden-Julian Oscillation is a tropical atmospheric phenomenon detected as anomalies in zonal winds, convection and cloudiness. This perturbation has a definitive timescale of about thirty to sixty days, allowing its signal to be extracted from ...

Long‐Term Observations Reveal Non‐Negligible Temperature Contributions to Moist Static Energy During the MJO Transition From Suppressed to Active Phases

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The evolution of moist static energy (MSE) is widely used to understand the organization and propagation of the Madden‐Julian Oscillation (MJO). Past studies, largely based on reanalysis or short‐term observations, have highlighted humidity as the dominant driver of MJO evolution.

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.

ENSO Recharge Oscillator Theory Integrating the Southward Wind Shift

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The El Niño–Southern Oscillation (ENSO) is one of the most‐well understood climate phenomena, and the Recharge Oscillator (RO) theory is widely used to conceptualize its physics in observations and models. ENSO‐associated equatorial zonal wind anomalies shift southward in boreal winter, contributing to ENSO termination.

Observed connection between the Madden–Julian oscillation and the upper tropospheric biennial oscillation

Environmental Research Letters
It has been found that the quasi-biennial oscillation (QBO) in the stratosphere have an important impact on the Madden Julian oscillation (MJO). In this study, we show that there is an obvious biennial oscillation in the tropical upper troposphere, which

Revisiting Intrinsic Predictability of Wave‐Convection Coupled Bands Over Southern China: Variable and Scale‐Dependent Error Growth Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract This study investigates the variable‐ and scale‐dependent intrinsic predictability of wave‐convection coupled bands over southern China on 30 January 2018, using 1‐km simulations under varying initial moisture conditions. The predictability time is quantified via the Loss Predictability Index (LPI), defined as the ratio of the forecast error ...

Lagged Response of MJO Convection and Precipitation to Solar Ultraviolet Variations on Intraseasonal Time Scales

Geophysical Research Letters
Composite analyses of NOAA satellite‐based outgoing longwave radiation data and ERA5 reanalysis data for nearly six solar maximum periods support the existence of a response of tropical convection and precipitation to short‐term (∼27‐day) solar ...

Potential Strengthening of the Madden–Julian Oscillation Modulation of Tropical Cyclogenesis

Atmosphere
A typical Madden–Julian Oscillation (MJO) generates a large region of enhanced rainfall over the equatorial Indian Ocean that moves slowly eastward into the western Pacific.
