Descrizione del progetto
Un nuovo modo per calcolare il comportamento delle tempeste
La previsione di eventi meteorologici gravi, quali le pesanti precipitazioni e i venti impetuosi, riveste un ruolo importante, in quanto fornisce alle comunità il tempo di prepararsi in anticipo per affrontarle meglio. Queste informazioni sono inoltre cruciali per il settore del trasporto aereo, poiché permettono di prevedere i ritardi e le azioni da intraprendere. Il progetto PERSEVERE, finanziato dall’UE, sta indagano l’uso delle reti neurali, in particolare di quelle informate dalla fisica, che coniughino l’apprendimento automatico basato sui dati e i modelli fisici, con l’obiettivo di prevedere lo stato fluido dell’atmosfera nelle regioni che interessano il traffico aereo. PERSEVERE approfondirà inoltre lo sviluppo di reti generative avversarie dedicate per migliorare e completare l’esito delle reti neurali informate dalla fisica, migliorando la precisione della previsione e integrando variabili aggiuntive quali la temperatura e l’umidità dell’aria.
Obiettivo
The novel development of Physics-Informed Neural Networks (PINNs), which incorporate the constraints given by physics laws into the training process, as excellent means of computing fluidic fields and their characteristics such as velocity and pressure has open the gates to numerous applications. One of them is the data enhancement of experiments, since PINNs can reconstruct by means of applying the Navier-Stokes equations as loss function the full fluid domain in areas where experiments are limited by technology. On the other hand, the development of Generative Adversarial Networks (GANs) as robust networks with excellent precision but excessive computational costs leaves the door open to further investigate new applications where PINNs and GANs can be combined to amplify their strengths and reduce their weak points. One of those applications regards the forecast of severe weather conditions, where PINNs are useful to compute the fluidic behavior of storms approaching a certain location, whereas GANs can incorporate many additional parameters, such as wind speed, humidity, temperature and electric content, which may be essential to determine if in the following 48h a certain location is going to suffer from severe weather conditions.
The estimation and forecast of storms is essential to the air transport industry, since the losses incurred due to delays and deviations of air traffic caused by the presence of storms have been reported to be over $38.5 billion in USA. The development of a computational architecture which is able to determine if severe weather events are going to take place within the next 48h is therefore of crucial importance. There exists no model nor application in which the combined strengths of PINNs and GANs have been put into practice, one to rapidly estimate the fluidic behaviour of a moving storm, the second to calculate the properties of the field with high precision.
