摘要

Atmospheric blocking often results in significant weather extremes and associated impacts such as heatwaves, droughts, wildfires, cold spells, and floods in mid-latitude regions. However, the physical processes behind blocking and associated extreme weather events are not well understood, hampering prediction and decision-making for mitigation and adaptation. Further, numerical models often struggle to simulate the frequency, duration, and geographic distribution of atmospheric blocking events. Here, we provide an overview of blocking-related weather extremes and impacts, as well as of our current understanding of the key physical processes. We identify knowledge gaps and current challenges and provide our perspective on potential ways forward.
