Sea ice loss of the Barents-Kara Sea enhances the winter warming over the Tibetan Plateau
Abstract The Tibetan Plateau (TP) is known as one of the most sensitive regions to climate change, and it has experienced accelerated warming in recent decades. However, to what degree the TP warming amplification relates to remote forcing such as sea ice loss in the Arctic sea ice remains unclear....
