Frontiers in Marine Science, 2023 The interannual-decadal variability in the upper-ocean salinity of the southeast Indian Ocean (SEIO) was found to be highly correlated with the El Niño-Southern Oscillation (ENSO).

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.

Representing the Indian Ocean Dipole
, 2022 Representing the Indian Ocean DipolePurpose. This paper offers an alternative representation of the Indian Ocean Dipole. Instead of the zonal gradient of equatorial sea surface temperature, the new index uses tropical sub-surface temperatures (T100 ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study reveals that the combined effects of the North Atlantic Oscillation (NAO) and anomalous Indo‐Pacific Walker circulation on the excitation of the wave train along the wintertime subtropical jet strongly depend on their phase combination. Their impacts interfere constructively or destructively over South Asia, leading to notable differences in

Positive Indian Ocean Dipole events precondition southeast Australia bushfires
, 2009 [1] The devastating “Black Saturday” bushfire inferno in the southeast Australian state of Victoria in early February 2009 and the “Ash Wednesday” bushfires in February 1983 were both preceded by a positive Indian Ocean Dipole (pIOD) event.

Ensemble reliability and the signal‐to‐noise paradox in ECMWF subseasonal forecasts
Quarterly Journal of the Royal Meteorological Society, EarlyView.We derive a general expression for the ratio of predictable components (RPC) in terms of correlation, spread–error ratio, and total variance ratio. Physical constraints on the admissible solutions (i.e., real‐valued and non‐negative variances) provide a mechanism to identify statistically paradoxical sample combinations of reliability and correlation ...

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.

A retrospective on the 2025 Atlantic hurricane season
Weather, EarlyView.The 2025 Atlantic hurricane season was intermittent, with extended quiet periods separated by three clusters of activity. The broad‐scale conditions were often unfavourable for cyclogenesis and common drivers of activity such as La Niña were weak, but well above‐average sea temperatures still supported intense storms.

The Response of the Indian Ocean Dipole Asymmetry to Anthropogenic Aerosols and Greenhouse Gases
, 2015 The tropical Indian Ocean has experienced a faster warming rate in the west than in the east over the twentieth century. The warming pattern resembles a positive Indian Ocean dipole (IOD) that is well captured by climate models from phase 5 of the ...
