Imprint of Indian Ocean Dipole on nitrous oxide dynamics

Limnology and Oceanography Letters
The northern Indian Ocean is a hotspot of nitrous oxide (N2O) emissions, with strong seasonal monsoons and interannual Indian Ocean Dipole (IOD) variability. We examine the IOD influence on N2O seasonality using a regional ocean model covering 1981–2020,

The influence of Indian Ocean Dipole (IOD) on biogeochemistry of carbon in the Arabian Sea during 1997–1998

Journal of Earth System Science, 2006
Data on ocean color chlorophylla (Chl a) obtained using Sea-viewing Wide Field of view Sensor (SeaWiFS), sea surface temperature (SST) by Advanced Very High Resolution Radiometer (AVHRR), and sea surface height (SSH) by TOPEX/POSEIDON were analyzed to examine the influence of Indian Ocean Dipole (IOD) on the physical and biogeochemical processes with ...

Observation Impact of Moored Buoys in the Eastern Tropical Indian Ocean During Boreal Winter Using Ensemble‐Based Forecast Sensitivity to Observations

Atmospheric Science Letters, Volume 27, Issue 6, June 2026.
Using 17 years of ensemble‐based forecast sensitivity to observations (EFSO), this study shows that marine meteorological observations in the eastern tropical Indian Ocean have significantly larger impacts during boreal winter than summer, despite similar observation frequencies.

Moderate Indian Ocean Dipole dominates spring fire weather conditions in southern Australia

Environmental Research Letters
Patterns of the Indian Ocean Dipole (IOD) exhibit strong diversity, ranging from being dominated by the western tropical Indian ocean (WTIO) to by the eastern tropical Indian ocean.

Strengthening of the Indian Ocean Dipole With Increasing Seasonal Cycle in the Mid‐Holocene

Geophysical Research Letters, 2019
This study presents modeling evidence that the Indian Ocean Dipole (IOD) is enhanced in its frequency and amplitude under mid‐Holocene (8‐ka) conditions.

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

Linking Salinity and Precipitation Through Moisture Transport: A Study for the North Atlantic

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Sea surface salinity (SSS) is a key indicator of the ocean–atmosphere freshwater balance and plays a central role in global moisture transport. This study investigates how extreme SSS anomalies in the North Atlantic (NATL) source region indicate atmospheric moisture pathways and precipitation in surrounding continental and island sink regions.

Relationship between the October–December rainfall in Tanzania and the Walker circulation cell over the Indian Ocean

Meteorologische Zeitschrift, 2019
Like most of the countries in the Great Horn of Africa, Tanzania is prone to floods and droughts. Anomalously wet years over the region are associated with low-level convergence, the advection of moisture from both the Indian Ocean and the Congo and an ...

Compound Mesoscale Convective Systems and Low‐Pressure Systems in Tropical Monsoon Regions: Assessing Their Meteorology and Precipitation

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Mesoscale convective systems (MCS) and low‐pressure systems (LPS) are both strongly associated with precipitation across the regions where they occur, particularly within global monsoon systems; however, their co‐occurrence and its relationship to precipitation have not been systematically examined.
