Eastward Propagation of Anomalous Indo–Pacific Walker Circulation During ENSO Transition

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract By analyzing the zonal mass streamfunction over the equatorial Indo–Pacific region in the period 1979–2024, we found that during the decaying phase of 13 out of 31 El Niño‐Southern Oscillation (ENSO) events, the anomalous Indo–Pacific Walker Circulation (IPWC) propagates steadily eastward across the warm pool.

Response of the West African Monsoon to the Madden–Julian Oscillation [PDF]

open access: yes, 2009
Observations show that rainfall over West Africa is influenced by the Madden-Julian Oscillation (MJO). A number of mechanisms have been suggested: 1) forcing by equatorial waves; 2) enhanced monsoon moisture supply; and 3) increased African easterly wave

Maintenance of Moisture Anomalies Across Synoptic and Intraseasonal Timescales Over the Indo‐Pacific Warm Pool

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Moisture variability plays a fundamental role in regulating tropical precipitation; however, the mechanisms that sustain moisture anomalies across different timescales remain unclear. This study examines how moisture anomalies are regulated over the Indo‐Pacific warm pool using the column‐integrated moist static energy (CMSE) budget.

Moisture Origin and Transport for Extreme Precipitation over Indonesia’s New Capital City, Nusantara in August 2021

open access: yesAtmosphere, 2022
Nusantara, Indonesia’s new capital city, experienced a rare extreme rainfall event on 27–28 August 2021. This heavy rainfall occurred in August, the driest month of the year based on the monthly climatology data, and caused severe flooding and landslides.

Climate fluctuations of tropical coupled system: The role of ocean dynamics [PDF]

open access: yes, 2006
The tropical oceans have long been recognized as the most important region for large-scale ocean–atmosphere interactions, giving rise to coupled climate variations on several time scales.

Understanding Interannual Variability of Brahmaputra River Basin Flows Through Bayesian Causal Networks

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Bayesian Causal Networks (BCNs) are adapted to investigate causal factors of hydroclimate variability in the Brahmaputra River Basin (BRB) during the seasonal and sub‐seasonal periods. This is the longest monsoonal river system in India, prone to frequent severe flooding.

Mechanism for northward propagation of boreal summer intraseasonal oscillation: Convective momentum transport [PDF]

open access: yesGeophysical Research Letters, 2010
This study demonstrates that the momentum transport by cumulus convection plays a significant role in the organization and northward propagation of intraseasonal (ISO) convection anomalies over the Indian and western Pacific regions during boreal summer.

Seasonal Predictions and Their Applications in the Mediterranean Region: Part I—Sources of Predictability and Prediction Skill

open access: yesInternational Journal of Climatology, Volume 46, Issue 5, April 2026.
The ability to predict climate fluctuations at seasonal timescales offers significant socio‐economic benefits. However, limited understanding of predictability mechanisms and model errors hinders forecast quality. Recent research has improved forecasting systems and data quality.

Weather types across the Maritime Continent: From the diurnal cycle to interannual variations

open access: yesFrontiers in Environmental Science, 2015
Six weather types (WTs) are computed across the Maritime Continent during austral summer (September--April) using cluster analysis of unfiltered, daily, low-level winds at 850 hPa, by a k-means algorithm.
