文摘Numerous observations and simulations have revealed that climate warming is not uniform across the Earth,especially during the boreal winter[1].One striking phenomenon is Arctic amplification(AA),which shows the Arctic is warming much faster than the global mean[2,3].This is evident in the reanalysis dataset,which indicates that,as shown in Fig.1a,the trend of winter surface air temperature at 2 m(SAT)averaged around the Arctic(65°-90°N)is 0.72 K 10a^(-1)。
