Connecting Arctic Changes to Global Weather Patterns: Exploring the Interplay

Abstract

Embarking on an urgent exploration of the profound decline in Arctic sea ice, this presentation underscores its extensive impact on global weather patterns and stresses the importance of comprehending Arctic weather variability (WV) for accurate forecasting and analysis of extreme weather events. In addressing the challenge of quantifying WV and its implications amidst human-induced climate change, we introduce an innovative complexity-based approach. Our investigation reveals a robust statistical correlation between intraseasonal WV in the Arctic and the Arctic Oscillation, shedding light on the heightened daily variability in Arctic sea ice—an outcome of its accelerated decline due to global warming. Delving into the interconnected dynamics, we unveil atmospheric teleconnections influencing regional patterns, posing elevated risks to human activities and forecast predictability. The analyses unearth a positive feedback loop between Arctic and global weather instabilities, providing profound insights into the intricate ways Arctic changes resonate worldwide. This comprehensive framework bridges complexity science, Arctic WV, and the wide-reaching implications that warrant collective attention and action.
