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

open access: yesnpj 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 ...

A New Hydroclimatic Signature: Negative NAO Dominance Under Weak La Niña Conditions During the 2025–2026 Northwest Africa Floods

open access: yesInternational Journal of Climatology, EarlyView.
Conceptual hydroclimatic pathway linking the concurrent negative North Atlantic Oscillation (NAO) phase and weak La Niña conditions to extreme February rainfall and flash flooding in Northwest Africa. ABSTRACT The winter of 2025–2026 in Morocco exhibited a rapid hydroclimatic transition from prolonged drought to widespread flooding, representing an ...

Atmospheric Rivers, Floods, and Flash Floods in California [PDF]

open access: yes, 2016
Atmospheric Rivers (ARs) are long (\u3e2000 km), narrow (\u3c 1000 km) corridors of enhanced vertically integrated water vapor (IWV) and enhanced IWV transport (IVT). The landfall of ARs along the U.S. West Coast have been linked to extreme precipitation

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

open access: yesJournal 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.

A framework for the analysis of the influence of rainfall spatial organization and basin morphology on flood response [PDF]

open access: yes, 2013
This work describes the derivation of a set of statistics, termed spatial moments of catchment rainfall, that quantify the dependence between rainfall spatial organization, basin morphology and runoff response.

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

open access: yesInternational 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 ...

Assessment of flash floods taking into account climate change scenarios in the Llobregat River basin [PDF]

open access: yes, 2013
Global change may imply important changes in the future occurrence and intensity of extreme events. Climate scenarios characterizing these plausible changes were previously obtained for the Llobregat River basin (NE Spain).

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

open access: yesEgyptian 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.

Flash floods [PDF]

open access: yes, 2015
The thesis presents flash floods phenomenon and the differences between flash floods and\ud other types of floods. Flooding is usually caused by intense or long-lasting rainfall event.\ud These kinds of events are more often in the last years and climate

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

open access: yesInternational 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.
