Statistical modelling of tropical cyclone tracks: modelling cyclone lysis

TL;DR

This paper presents an improved statistical model for tropical cyclone tracks by focusing on the lysis (death) process, which significantly enhances overall track prediction accuracy.

Contribution

It introduces a detailed lysis modeling approach that advances previous cyclone track models by improving their predictive performance.

Findings

Enhanced track model accuracy with better lysis representation

Lysis modeling significantly impacts overall cyclone track predictions

Progresses the statistical modeling of tropical cyclone lifecycle stages

Abstract

We describe results from the fifth stage of a project to build a statistical model of tropical cyclone tracks. The previous stages considered genesis and the shape of tracks. We now consider in more detail how to represent the lysis (death) of tropical cyclones. Improving the lysis model turns out to bring a significant improvement to the track model overall.
