Short Summary

This study presents new metrics and evidence linking rapid Arctic warming to more frequent high-amplitude jet-stream configurations, suggesting an increase in persistent extreme weather events.

Objective

• To present new metrics and evidence supporting a linkage between rapid Arctic warming and more frequent high-amplitude (wavy) jet-stream configurations that favor persistent weather patterns.

Study Configuration

• Spatial Scale: Arctic, Northern Hemisphere mid-latitudes, regional patterns.
• Temporal Scale: Seasonal patterns.

Methodology and Data

• Models used: Not specified in the provided text.
• Data sources: Not explicitly stated, but the study relies on atmospheric data to derive new metrics and evidence.

Main Results

• Robust relationships were found among seasonal and regional patterns of weaker poleward thickness gradients, weaker zonal upper-level winds, and a more meridional flow direction.
• Rapid Arctic warming, relative to Northern Hemisphere mid-latitudes, is linked to more frequent high-amplitude (wavy) jet-stream configurations.
• These configurations favor persistent weather patterns.
• The frequency of extreme weather events caused by persistent jet-stream patterns is projected to increase as the Arctic continues to warm faster than elsewhere due to rising greenhouse-gas concentrations.

Contributions

• Presents new metrics and evidence supporting a linkage between Arctic warming and increased frequency of high-amplitude jet-stream configurations.
• Provides further evidence for the connection between Arctic amplification and persistent extreme weather events.
