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 ...

Peering into the microphysics of the Madden‐Julian Oscillation [PDF]

Eos, Transactions American Geophysical Union, 2014
The onset of the active phase of the Madden‐Julian Oscillation (MJO) is marked by the formation of a region of deep convection and enhanced precipitation over the Indian Ocean. Generally persisting from 30 to 60 days as it progresses slowly eastward, the MJO consists of wet active phases alternating with suppressed periods of lower rainfall and reduced

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.

Precipitation Budget of the Madden–Julian Oscillation

Journal of the Atmospheric Sciences, 2017
Abstract Column moisture and moist static energy (MSE) budgets have become common tools in the study of the processes responsible for the maintenance and evolution of the MJO. While many studies have shown that precipitation is spatially correlated with column moisture, these budgets do not directly describe the MJO-related precipitation

Global warming weakens Maritime Continent barrier effect on MJO propagation

Environmental Research Letters
As the Indo-Pacific warm pool expands in a warming climate, the probability of an MJO event successfully propagating through the Maritime Continent (MC) is projected to increase by 29.3% by the late 21st century under the SSP5-8.5 scenario. This enhanced

INTRASEASONAL VARIABILITY OF RAINFALL OVER NORTHERN SOUTH AMERICA AND CARIBBEAN REGION

Earth Sciences Research Journal, 2008
Based on decadal (amounts for each ten days) precipitation data from meteorological stations situated in Northern South America and Caribbean region, a decadal precipitation index (DPI) was calculated in order to study the intraseasonal variability (ISV)

Modulation of Atlantic Aerosols by the Madden-Julian Oscillation [PDF]

Much like the better-known EI Nino-Southern Oscillation, the Madden-Julian Oscillation (MJO) is a global-scale atmospheric phenomenon. The MJO involves periodic, systematic changes in the distribution of clouds and precipitation over the western Pacific ...
