Abans de marxar de vacances vàrem rebre l’excel·lent notícia de la publicació de l’article a Atmosphere en el que es recullen els resultats del Nowcasting de radar als casos d’estudi del projecte #SINOPTICA.

Abstract
Effective and time-efficient aircraft assistance and guidance in severe weather environments remains a challenge for air traffic control. Air navigation service providers around the globe could greatly benefit from specific and adapted meteorological information for the controller position, helping to reduce the increased workload induced by adverse weather. The present work proposes a radar-based nowcasting algorithm providing compact meteorological information on convective weather near airports for introduction into the algorithms intended to assist in air-traffic management. The use of vertically integrated liquid density enables extremely rapid identification and short-term prediction of convective regions that should not be traversed by aircraft, which is an essential requirement for use in tactical controller support systems. The proposed tracking and nowcasting method facilitates the anticipation of the meteorological situation around an airport. Nowcasts of centroid locations of various approaching thunderstorms were compared with corresponding radar data, and centroid distances between nowcasted and observed storms were computed. The results were analyzed with Method for the Object-Based Evaluation from the Model Evaluation tools software (MET-10.0.1, Developmental Testbed Center, Boulder, CO, US) and later integrated into an assistance arrival manager software, showing the potential of this approach for automatic air traffic assistance in adverse weather scenarios.

En la imatge es representen les sortides del producte de nowcasting en les proximitats de l’aeroport de Venècia – Marco Polo (creueta vermella dins del cercle) pel dia 7 de Juliol del 2019 entre les 12:10 i les 13:40 UTC. Les ombres gris fosc indiquen les tempestes actives, mentre que les gris clar són les localitzacions que han tingut en els passos de temps anteriors. Els puntets blaus indiquen les posicions dels centroides de les tempestes des de la primera identificació fins al temps present i els punts vermells i taronja són localitzacions que s’esperen pels pròxims 30–60 min (en intervals de 5 min). L’àrea grana indica la zona prevista d’afectació per la tempesta en els pròxims 60 minuts.
