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 ...

Climatology and Trends of Sub‐Daily Precipitation Extremes in Croatia

International Journal of Climatology, EarlyView.
Sub‐daily extreme precipitation indices reveal pronounced spatial variability, with the highest intensities and frequencies across the Adriatic region and the highlands. Seasonal and diurnal patterns highlight distinct regional behaviour, including summer maxima over the continental interior and nocturnal or early‐morning peaks along the Adriatic coast.

Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

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.

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

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.

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Flash floods simulation using Saint Venant equations

, 2007
Flash floods prediction is considered one of the important environmental issues worldwide. In order to predict when and where the flood wave will invade and attack our lives, and provide solutions to deal with this problem it is essential to develop a ...

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.
