Physics-informed nEuRal networks for SEVERe wEather event prediction

Projektbeschreibung

Ein neues Verfahren zur Berechnung des Sturmverlaufs

Die Vorausberechnung von Unwettern wie Starkregen und Stürmen ist wichtig, weil sie den Gemeinden Zeit gibt, sich besser vorzubereiten. Auch für den Luftverkehr sind diese Informationen von entscheidender Bedeutung, da Verspätungen und erforderliche Maßnahmen frühzeitig erkannt werden können. Das EU-finanzierte Projekt PERSEVERE untersucht den Einsatz neuronaler Netze, insbesondere durch Vorwissen geprägter neuronaler Netze, die datengesteuertes maschinelles Lernen und physikalische Modelle kombinieren, um den Fluidstatus der Atmosphäre in Regionen mit Auswirkungen auf den Luftverkehr zu prognostizieren. Darüber hinaus wird im Rahmen von PERSEVERE die Entwicklung spezieller „Generative Adversarial Networks“, erzeugender gegnerischer Netzwerke, erforscht, um die Ergebnisse von durch Vorwissen geprägten neuronalen Netzen zu verbessern und zu ergänzen, indem die Genauigkeit der Vorhersage erhöht sowie zusätzliche Variablen wie Temperatur und Luftfeuchtigkeit einbezogen werden.

Ziel

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.
