Machine-learning regression applied to diagnose horizontal visibility from mesoscale NWP model forecasts

Driss Bari, Abdelali Ouagabi
2020 SN Applied Sciences  
Current predictions of visibility are based on physical parametrizations in mesoscale models and are thus limited with respect to accuracy.  ...  Low-visibility conditions are a weather hazard that affects all forms of transport, and accurate forecasting of their spatial coverage is still a challenge for meteorologists, particularly over a large  ...  Siham Sbii and Dr. Mohamed Nabhani from the Moroccan Weather Service are acknowledged for the fruitful discussions during this study and for their comments on an early version of the manuscript.  ...

Persistence in complex systems

S. Salcedo-Sanz, D. Casillas-Pérez, J. Del Ser, C. Casanova-Mateo, L. Cuadra, M. Piles, G. Camps-Valls
2022 Physics reports  
Persistence is an important characteristic of many complex systems in nature, related to how long the system remains at a certain state before changing to a different one.  ...  We also present and discuss some relevant results on persistence, and give empirical evidence of performance in different detailed case studies, for both short-term and long-term persistence.  ...  Acknowledgments This research has been partially supported by the project PID2020-115454GB-C21 of the Spanish Ministry of Science and Innovation (MICINN).  ...
