Data Fusion Exercise for Flash Flood Warnings: 26 July 2021 Flash Flood Event

Introduction

This training session will build on data fusion methodologies from the Data Fusion section of the WOC Severe Course (updated in FY21). We will apply these data fusion concepts to a flash flood case. We highlight contrasting scenarios, one with a nearby radar and the other where the closest radar was unavailable due to a recent lightning strike. Data fusion techniques are utilized to learn how to blend all available data which can be applied to short-term forecast and warning operations of flash flood events.
