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 ...

Satellite-observed precipitation and total column water vapor

Frontiers in Environmental Science
This study explores the relationship between water vapor and rainfall intensities over three tropical lands (Amazon Basin, Sahel, southern South America) and three tropical ocean regions (Atlantic Ocean, Indian Ocean, Niño 4).

Recurving tropical cyclones in the western North Pacific are stronger than non‐recurving ones: Causes and implications

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the statistical characteristics of recurving tropical cyclones (TCs) over the western North Pacific (WNP). We find that recurving TCs are, on average, 38% stronger than non‐recurving TCs, owing to longer ocean exposure, fewer landfalls, and passage through warmer, more favorable thermal environments.

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 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 ...

Nutrient supply controls particulate elemental concentrations and ratios in the low latitude eastern Indian Ocean

Nature Communications, 2018
The Indian Ocean provides a unique environmental gradient to test underlying drivers of the elemental composition of particulate organic matter. Here the authors show that nutrient supply, over temperature and biodiversity changes, controls regional ...

Cyclone Ditwah (2025): moderate‐intensity tropical cyclone brings record flooding and damage to Sri Lanka

Weather, EarlyView.
Cyclone Ditwah (2025) made landfall in Sri Lanka as a tropical cyclone with only moderate intensity winds (~65–75kmh−1). Yet, its prolonged heavy rainfall also led to landslides and widespread flooding across Sri Lanka and the southern Indian states, with the combined effects of hazards causing impacts totalling 4.1 billion USD. Ditwah is, therefore, a

Unraveling the interactions between tropical Indo-Pacific climate modes using a simple model framework

npj Climate and Atmospheric Science
The dominant interannual climate phenomena are mainly observed in the tropical Indo-Pacific Ocean. While climate modes such as the El Niño–Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Indian Ocean Basin (IOB) can develop through intrinsic ...

Global warming hiatus contributed to the increased occurrence of intense tropical cyclones in the coastal regions along East Asia

Scientific Reports, 2018
The recent global warming hiatus (GWH) was characterized by a La Niña–like cooling in the tropical Eastern Pacific accompanied with the Indian Ocean and the tropical Atlantic Ocean warming.

Extreme rainfall in southern China in April 2024 and its potential link to weather events across south Asia

Weather, EarlyView.
This study documents the unseasonal and prolonged heavy rain events which occurred in southern China during April 2024. In this series of extreme rainfall events, Guangdong province recorded extreme rainfall exceeding 6‐sigma of climatology, with eleven cities reporting record‐breaking rainfall.
