This analysis shows how Arctic surface air temperature (SAT) extremes have changed throughout time. Using ERA5 reanalysis, we demonstrate a pan-Arctic (>60°N) significant upward SAT trend of +0.62°C/decade since 1979. Due to this warming, the warmest days of each month in the 1980s–1990s would be considered average today, while the present coldest days would be regarded as normal in the 1980s–1990s. Over 1979–2021, there was a 2°C (or 7%) reduction of pan–Arctic SAT seasonal cycle, which resulted in warming of the cold SAT extremes by a factor of two relative to the SAT trend and dampened trends of the warm SAT extremes by roughly 25%. Since 1979, autumn has seen the strongest increasing trends in daily maximum and minimum temperatures, as well as counts of days with SAT above the 90th percentile and decreasing trends in counts of days with SAT below the 10th percentile, consistent with rapid Arctic sea ice decline and enhanced air-ocean heat fluxes. The modulated SAT seasonal signal has a significant impact on the timing of extremely strong monthly cold and warm spells. The dampening of the SAT seasonal fluctuations is likely to continue to increase as more sea ice melts and upper-ocean warming persists. As a result, the Arctic winter cold SAT extremes may continue to exhibit a faster rate of change than that of the summer warm SAT extremes as the Arctic continues to warm.}, number={8}, journal={JOURNAL OF CLIMATE}, author={Polyakov, Igor V. and Ballinger, Thomas J. and Lader, Rick and Zhang, Xiangdong}, year={2024}, month={Apr}, pages={2381–2404} }
