Flood Risk on the Rise

A recent study by the Wegener Center at the University of Graz explores how climate change is influencing "cut-off lows" (COLs) — upper-level low-pressure systems that become detached from the jet stream. These systems can linger over the same area for days, often bringing persistent heavy rainfall and increasing the risk of flooding.

By analyzing 18 climate models, researchers found that COLs are likely to shift further north and occur more often in spring rather than just in summer or fall. Regions like Canada, Northern Europe, Siberia, and China may experience more frequent and intense spring rainfall events.

The study underscores the need for improved flood protection measures such as river restoration and early warning systems to help reduce the impacts of these extreme weather patterns.
