Spatiotemporal Evolution of Regional Heavy Rainfall Events in Guangdong, South China: Intensification and Expansion Since the Early 1990s

International Journal of Climatology, EarlyView.
Regional heavy rainfall events (RHREs) in Guangdong, South China, during 1961–2025 are reassessed using an improved strength index that integrates rainfall intensity, spatial extent and duration. Results reveal a post‐1991 shift towards more frequent and spatially extensive strong and extreme events, with June showing the most pronounced ...

Identification of tropical cyclone–related flash floods from hazard narratives using a large language model–based approach

npj Natural Hazards
This study employs a Large Language Model (LLM)–based approach to identify tropical cyclones (TCs)-related flash floods and understand their interrelationships using hazard narratives from the National Centers for Environmental Information Storm Events ...

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

International Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

On the Uncertainties of Flash Flood Guidance: Toward Probabilistic Forecasting of Flash Floods

Journal of Hydrometeorology, 2006
Abstract Quantifying uncertainty associated with flash flood warning or forecast systems is required to enable informed decision making by those responsible for operation and management of natural hazard protection systems. The current system used by the U.S.

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Performance of multi-level association rule mining for the relationship between causal factor patterns and flash flood magnitudes in a humid area

Geomatics, Natural Hazards & Risk, 2019
Integrated with K-means clustering and Apriori algorithm, the multi-level association rule mining is proposed to investigate the causal factor patterns of flash floods, which consists of the following three steps: first, the association between causal ...

Identification of flash flood hazard zones in mountainous small watershed of Aceh Besar Regency, Aceh Province, Indonesia

Egyptian Journal of Remote Sensing and Space Sciences, 2016
Flash-floods develop at space and time scales that conventional observation systems were not able to monitor for rainfall, stream flow and sediment discharge. This condition resulted in greater casualties and tremendous economic losses.

Assessment of the Exposure of Australia to Tropical Cyclones Through a Climatological Model for Cyclone Weather Extent

International Journal of Climatology, EarlyView.
Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...

Shifting Patterns of Precipitation Extremes in the Southeast Atlantic Basin—Brazil: From Observed Trends to Future Projections

International Journal of Climatology, EarlyView.
Observed trends and EC‐Earth3 climate model projections demonstrate expressive changes in the Southeast Atlantic Hydrographic Basin, Brazil. Significant increases in rainfall intensity and dry spell duration in the present climate are followed by projected amplification of extreme precipitation under future warming, particularly under the SSP5‐8.5 ...

Aflatoxin contamination in dried fruits and nuts in Bangladesh: Occurrence, dietary exposure, and health risk assessment

JSFA reports, EarlyView.
Abstract Background Dried fruits and nuts are widely consumed for their desirable sensory qualities and high nutritional value, providing essential nutrients such as proteins, healthy fatty acids, potassium, dietary fiber, and bioactive compounds. However, they are highly susceptible to aflatoxin contamination, particularly in humid tropical regions ...
