Introduction

Storm Karl affected northern Europe regionally with high-impact weather in September 2016. The storm was created through extra-tropical conversion of a previous Tropical Storm event. When crossing the North Atlantic it merged with other lower pressure systems and invigorated, resulting in high wind speeds in Scotland and intense precipitation (with local flooding) in Norway.

This storm event was studied extensively during the NAWDEX flight campaign in connection with atmospheric moisture transport.
