1 Introduction Rapid Arctic warming is a robust feature of the ongoing climate change, with significant impacts on Arctic ecosystems and climate. Arctic warming rate is not homogeneous over time, with decadal-to-multidecadal variations that modulate the long-term warming trend (e.g., Bokuchava & Semenov, 2021; Chylek et al., 2014; England et al., 2021; Johannessen et al., 2004; Serreze & Barry, 2011; Serreze & Francis, 2006) and affect midlatitude climate (Dai & Deng, 2022; Wang & Chen, 2021).
