Coincidence of increasingly volatile winters in China with Arctic sea-ice loss during 1980–2018
Abstract Despite intense discussions on the recent boom of mid-latitude wintertime cold extremes, co-variations of warm and cold extremes, i.e. winter temperature volatility, has garnered substantially less attention. Apart from using temperature extremes’ frequency and intensity, we also define ‘te...
