Fig. 9: Another alternate definition of cold extremes still shows a divergence between Arctic and cold extremes trends in the US.
From: No detectable trend in mid-latitude cold extremes during the recent period of Arctic amplification

a Similar to Fig. 4 (b, e) for the CEUS, except for DJF daily Tmin less than 1.5 standard deviations of climatological DJF Tmin for the region 1990–2023, b similar to Fig. 4 (b, e) for the CEUS, except using the DJF 10% coldest daily Tmax anomalies for the region (compared to the distribution of DJF 5-day rolling means of Tmax anomalies for each calendar day 1990–2023).
