recommendations! Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2016jc012527

Abstract: Using the Geophysical Fluid Dynamics Laboratory Climate Model version 2p1, we explored the precursory disturbances that are most likely to develop into a positive Indian Ocean Dipole (IOD). The dominant spatial patterns of these precursors… read more here.

DOI: 10.1002/joc.8463

Abstract: In this study, hindcasts from eight Copernicus Climate Change Service (C3S) and three North American Multi‐Model Ensemble (NMME) operational seasonal forecast systems, based on dynamical climate models, are employed to investigate the influence of the… read more here.

recommendations! Published in 2025 at "International Journal of Climatology"

DOI: 10.1002/joc.8792

Abstract: In light of the importance of the formation of dipoles in the Indian Ocean (IO), it becomes pertinent to investigate whether or not such events are inherently predictable. The authors investigate if the formation of… read more here.

recommendations! Published in 2024 at "Quarterly Journal of the Royal Meteorological Society"

DOI: 10.1002/qj.4854

Abstract: Tropical–Antarctic teleconnections are known to have large impacts on Antarctic climate variability at multiple timescales. Anomalous tropical convection triggers upper‐level quasi‐stationary Rossby waves, which propagate to high southern latitudes and impact the local environment. Here… read more here.

DOI: 10.1007/s10236-019-01318-7

Abstract: Roles of atmospheric variabilities in the formation of Indian Ocean Dipole (IOD) were investigated using an ocean general circulation model and different atmospheric forcing datasets. Simulated IODs indicated that IOD amplitude decreased without intraseasonal variability… read more here.

DOI: 10.1007/s13131-019-1457-1

Abstract: The Impact of the Indian Ocean Dipole (IOD) and the El Niño Southern Oscillation (ENSO) event for Indonesian rainfall has been investigated for the period from 1950 to 2011. Inter-annual change of IOD and ENSO… read more here.

recommendations! Published in 2021 at "Geophysical Research Letters"

DOI: 10.1029/2020gl091497

Abstract: The positive Indian Ocean Dipole (IOD) event in 2019 was among the strongest on record, while the Indian Summer monsoon (ISM) was anomalously dry in June then very wet by September. We investigated the relationships… read more here.

DOI: 10.1029/2023gl105258

Abstract: Strong positive Indian Ocean Dipole (pIOD) events like those in 1997 and 2019 caused significant flooding in East Africa. While future projections indicate an increase in pIOD events, limited historical data hinders a comprehensive understanding… read more here.
