Utilization of remote sensing data for mapping the effect of Indian Ocean Dipole (IOD) and El Nino Southern Oscillation (ENSO) in Sumatra Island

IOP Conference Series: Earth and Environmental Science, 2021
Abstract IOD and ENSO are two global phenomena that are quite influencing the territory of Indonesia. Sumatra is one of the islands in Indonesia with unique local characteristics and is located in the westernmost. This study attempts to analyze how much the IOD and ENSO have affected rainfall in the Sumatra Island and which is more ...

Subseasonal Predictability of Weekly Rainfall and Rainy Season Onset Over East Africa

International Journal of Climatology, EarlyView.
This study evaluates the subseasonal predictability of weekly rainfall and rainy season onset over East Africa using the ECMWF extended range forecast model. Results show strong skill in forecasting weekly rainfall up to 4 weeks ahead, with higher accuracy during the March–May ‘long rains’ season.

Why is the amplitude of the Indian ocean dipole overly large in CMIP3 and CMIP5 climate models?

, 2013
[1] The Indian Ocean Dipole (IOD) affects weather and climate in many parts of the world, but a realistic simulation of the IOD in state-of-the-art climate models remains a challenge.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Salinity Indian Ocean Dipole: Another facet of the Indian Ocean Dipole phenomenon from satellite remote sensing

Science of Remote Sensing
Using satellite-measured sea surface salinity (SSS) from the Aquarius and Soil Moisture Active Passive (SMAP) missions since 2011, we show that SSS in the Equatorial Indian Ocean (EIO) experienced dipolar changes in the well-defined east EIO and west EIO

Improved Indian Ocean dipole seasonal prediction in the new generation of CMA prediction system

Geoscience Letters, 2023
Seasonal prediction of the Indian Ocean dipole (IOD) is important, considering its impact on the climate of surrounding regions. Here we compare the prediction of the IOD in two generations of prediction system developed by the China Meteorology ...

An Atmosphere–Land–Ocean Coupled Global NWP System: Performance Evaluation for Potential Operational Use

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract This study assesses the influence of ocean–atmosphere coupling on short‐ and medium‐range forecasts of the July 2024 Indian summer monsoon using the newly configured coupled NCMRWF Unified Model (C‐NCUM). Forecasts are evaluated against the operational atmosphere–land model (NCUM) using GPM rainfall, OSTIA SSTs, and reanalysis‐derived moisture

The prediction skill of Indian Ocean dipole mode in DCPP-CMIP6 decadal hindcast models

Environmental Research Communications
The Indian Ocean dipole (IOD) mode events are one of the most fascinating interannual ocean-atmosphere phenomenon in the tropical Indian Ocean. The zonal contrast of tropical ocean conditions foists enormous unfavorable impacts on the regional weather ...

The increased frequency of combined El Niño and positive IOD events since 1965s and its impacts on maritime continent hydroclimates

Scientific Reports, 2022
The Indian and Pacific Oceans surround the Maritime Continent (MC). Major modes of sea surface temperature variability in both oceans, including the Indian Ocean Dipole (IOD) and El Niño–Southern Oscillation (ENSO), can strongly affect precipitation on ...

The Tropical Indo‐Pacific and North Atlantic Precursors for the Interannual Variation of Extreme Humid‐heat Days in the Yangtze River Basin

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Extreme humid‐heat events pose a major hazard across the Yangtze River Basin (YRB), yet their underlying mechanisms and seasonal predictability remain insufficiently understood. Here, using observational diagnostics and coupled model experiments, we identify three independent drivers in the tropical Indo‐Pacific and subtropical North Atlantic ...
