Skill in nowcasting high-impact heavy precipitation events
Bech, Joan; Berenguer Ferrer, Marc (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 ... -
Stratiform and convective rain classification using machine learning models and micro rain radar
Ghada, Wael; Casellas Masana, Enric; Herbinger, Julia; Garcia Benadí, Albert; Bothmann, Ludwig; Estrella, Nicole; Bech, Joan; Menzel, Annette (Multidisciplinary Digital Publishing Institute (MDPI), 2022-09-13)

Pineda Rüegg, Nicolau; Bech, Joan; Rigo, Tomeu; Montañá Puig, Juan; Van der Velde, Oscar Arnoud (2009)
Comunicació de congrés
Accés restringit per decisió de l'autorThis study presents an analysis of total lightning and radar data of a severe weather event that took place in the early morning of 2nd November 2008 in Catalonia (NE Spain). A general overview of the synoptic framework ... -
Vertical structure and microphysical observations of winter precipitation in an inner valley during the Cerdanya-2017 field campaign
González Herrero, Sergi; Bech, Joan; Garcia Benadí, Albert; Udina Sistach, Mireia; Codina Sánchez, Bernat; Trapero, Laura; Georgis, Jean-Francois (2021-12-15)
Article
Accés obertPrecipitations processes at windward and leeward sides of the mountains have been object of study for many decades. Instead, inner mountain valleys, where usually most mountain population lives, have received considerably ... -
Vertically resolved precipitation intensity retrieved through a synergy between the ground-based NASA MPLNET lidar network measurements, surface disdrometer datasets and an analytical model solution
Lolli, S.; D'Adderio, L.P.; Campbell, J.R.; Sicard, Michaël; Welton, E.J.; Binci, A.; Rea, Alessandro; Tokay, A.; Comerón Tejero, Adolfo; Barragán Cuesta, Rubén; Baldasano Recio, José María; González, Sergio; Bech, Joan; Afflitto, Nicola; Lewis, J.R.; Madonna, Fabio (Multidisciplinary Digital Publishing Institute (MDPI), 2018-07-01)
Article
Accés obertIn this paper, we illustrate a new, simple and complementary ground-based methodology to retrieve the vertically resolved atmospheric precipitation intensity through a synergy between measurements from the National Aeronautics ...
