“…Firstly, for example, some evidence is apparent of an increase in moisture transported from the extratropics to polar regions during the spring, with a consequent increase in the radiative forcing of water vapor contributing to melting (Kapsch, Graversen, & Tjernström, ); secondly, there has been an apparent increase in moisture transport in winter, related to an increase in precipitation in catchments that drain into the Arctic, which subsequently produces an increase in summer discharge and contributes to Arctic Ice Melting (Zhang et al, ). The implications of moisture transport for precipitation on the Arctic SIE are diverse and difficult to quantify, because the changes in precipitation are associated with opposing mechanisms, depending on the form of precipitation (rain or snow), as well as its intensity and seasonality (Gimeno‐Sotelo, Nieto, Vázquez, & Gimeno, , ; Vihma et al, ).…”
