In recent decades, we have witnessed rapid changes in the Arctic climate, with the rate of warming three to four times exceeding global averages. This mysterious "warm Arctic, cold Eurasia" climate phenomenon has profound implications and is fueling scientific curiosity about its underlying mechanisms. Arctic sea ice is declining rapidly, shrinking by about 12.2 % per decade in summer over the past 40 years. Earlier studies suggested that shrinking Arctic sea ice played a key role in driving the "Warm Arctic, Cold Eurasia" climate regime. However, limitations in available observations have raised questions about whether internal atmospheric variability may be masking the true impact of reduced sea ice.
