Radar-based rainfall nowcasting at European scale: long-term evaluation and performance assessment
(2013)
Text en actes de congrés
Accés obertThis work studies the performance of CRAHI's algorithm for rainfall nowcasting at European scale using the mosaics produced within the EUMETNET project OPERA (with a resolution of 4 km and 15 minutes) in the framework of ... -
ReAFFIRM: Real-time Assessment of Flash Flood Impacts: a Regional high-resolution Method
(Elsevier, 2020-03)
Article
Accés obertFlash floods evolve rapidly in time, which poses particular challenges to emergency managers. One way to support decision-making is to complement models that estimate the flash flood hazard (e.g. discharge or return period) ... -
REAL - Ensemble radar precipitation estimation for hydrology in a mountainous region
(2009-02-06)
Article
Accés obertAn elegant solution to characterise the residual errors in radar precipitation estimates is to generate an ensemble of precipitation fields. The paper proposes a radar ensemble generator designed for usage in the Alps using ... -
Real-time assessment of flash flood impacts at pan-European scale: the ReAFFINE method
(Elsevier, 2021-12)
Article
Accés obertThe development of early warning systems (EWSs) is a key element for the effective mitigation of flash flood impacts. Emergency managers and other end-users increasingly recognise the benefit of tools that automatically ... -
Reconstruction of radar reflectivity in clutter areas
(2013)
Comunicació de congrés
Accés obertThe production of Radar Quantitative Precipitation Estimates (QPE) requires processing the observations to ensure their quality and its conversion into the variable of interest (e.g., precipitation rates). Some of the steps ... -
SBMcast - An ensemble nowcasting technique to assess the uncertainty in rainfall forecasts by Lagrangian extrapolation
(Elsevier Science Direct, 2011-07-11)
Article
Accés restringit per política de l'editorialDeterministic nowcasting based on Lagrangian extrapolation of recent radar observations is a technique used in many operational and research centers and has proven to be useful at extending the anticipation with which flows ... -
Scale analysis of the diurnal cycle of precipitation over Continental United States
(2010)
Comunicació de congrés
Accés obertRainfall initiation is related to diurnal and semidiurnal radiation forcing (e.g. Wallace 1975, Carbone et al. 2002, Surcel et al. 2010). Much of the observed warm season rainfall results from a thermodynamic response to ... -
Scale characterization and correction of diurnal cycle errors in MAPLE
(2017-09)
Article
Accés obertThe most widely used technique for nowcasting of quantitative precipitation in operational and research centers is the Lagrangian extrapolation of the latest radar observations. However, this technique has a limited forecast ... -
Sistema de alerta para procesos torrenciales a escala regional combinando mapas de susceptibilidad y datos del radar meteorológico
(International Centre for Numerical Methods in Engineering (CIMNE), 2017)
Text en actes de congrés
Accés obertLos procesos torrenciales como las corrientes de derrubios o flujos hiperconcentrados causan frecuentemente daños importantes e incluso muertos en zonas montañosas. Para afrontar este peligro, los sistemas de alerta son ... -
Skill in nowcasting high-impact heavy precipitation events
(2014)
Comunicació de congrés
Accés obertThe objective of this study is to assess the skill of a precipitation nowcasting (very short range forecasting) system, with particular emphasis on hig-impact Heavy Precipitation Events (HPE). A threshold amount of 20 mm ... -
Spatiotemporal precipitation estimation from rain gauges and meteorological radar using geostatistics
(2021-05)
Article
Accés obertAutomatic interpolation of precipitation maps combining rain gauge and radar data has been done in the past but considering only the data collected at a given time interval. Since radar and rain gauge data are collected ... -
The diurnal cycle of precipitation from continental radar mosaics and numerical weather prediction models. Part II: intercomparison among numerical models and with nowcasting
(American Meteorological Society, 2012-08)
Article
Accés obertThis second part of a two-paper series compares deterministic precipitation forecasts from the Storm-Scale Ensemble Forecast System (4-km grid) run during the 2008 NOAA Hazardous Weather Testbed (HWT) Spring Experiment, ... -
The use of NWP forecasts to improve an ensemble nowcasting technique
(2014)
Comunicació de congrés
Accés obertQuantitative Precipitation Nowcasting (QPN) is one of the main applications of radar observations. On one hand, one of the most used nowcasting algorithms is Lagrangian extrapolation. It shows skill in specifying the timing ... -

Validation of a nowcasting technique from a hydrological perspective
(2004)
Text en actes de congrés
Accés obertNowcasting precipitation is a key point to anticipate risks in flood warning systems. In this environment, weather radars are very useful because of the high resolution of their measurements both in time and space. The ... -

WiBasin: basin management through an integrated platform
(2014)
Text en actes de congrés
Accés obertIn this work we present WiBasin, a cloud platform for basin and dam management. It includes different sources of precipitation (both observed and forecasted), integration over the catchment domain (to provide an aggregated ...
