Short summary
Extratropical cyclones (ETCs) drive severe weather and cause significant socio-economic impacts. We present ImpactETC1.0, a framework that identifies ETC tracks and links them to local impacts, here storm surges. It uses global optimisation, BLOB analysis, and several post-processing options to improve tracking quality and identify impact-relevant tracks. Results show ImpactETC1.0 enables efficient, impact-focused ETC tracking.
