Severe storms events’ reproduction in the United States of America: Evaluation from the marked self-exciting point processes point of view

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.
