Analysis of vulnerability of ATM to weather phenomena

A quantitative analysis, based on available literature data, of the weather impact with respect to the affected Key Performance Areas will be carried out. Finally, the impacts on ATM operations associated to each considered weather phenomenon will be sorted according to properly evaluated severity level, in order to identify the most relevant ATM vulnerabilities wrt weather. The analysis will be based on the new European meteorological re-analysis ERA5 and its statistics of the severe episodes. Critical analysis of the limits and possibilities of improvement of meteo tools suitable to support ATM operations, while also considering perspective innovations in this field (i.e. methodological and technological trends) over the next decades.
