Abstract

The proposed application focuses on the evaluation of hailstorms’ and thunderstorms winds’ events in the United States of America, in the period from 1996 to 2022, by a marked spatio-temporal self-exciting point process estimation. The aim of this application is the assessment and explanation of the spatio-temporal spontaneous and reproducing activity of severe hailstorms’ and thunderstorms winds’ processes. Though the spatio-temporal dynamics of the underlying spatio-temporal process are not exactly evaluable according to the self-exciting processes’ theoretical framework, the present application allows us to demonstrate how the spatio-temporal pattern is well-fitted and clearly explainable, according to the flexible semi-parametric ETAS-FLP approach.
