Abstract
This article contains a review of the transport of moisture to the Arctic and its effect on Arctic Sea Ice Extent (SIE). The review includes a synthesis of our knowledge regarding the main sources supplying moisture to the Arctic, the changes experienced over the last few decades due to variations in the transport of moisture, the factors that control interannual variability, and the inherent contrast in the mechanisms related to the effect of changes in moisture transport on SIE in the Arctic. We note that the precise identification of the moisture sources for the Arctic depends both on the definition of the Arctic region itself and on the approach used to identify the sources, with the remote regions over the extratropical Atlantic and Pacific Oceans being universally important, as are some continental areas over Siberia and North America. This review also reaffirms the absence of any clear agreement regarding the trends in atmospheric moisture transport to the Arctic, and highlights discrepancies between different data sets and approaches in the quantification of moisture transport, implying that its long‐term impact on the intensification of the hydrological cycle in the Arctic remains unclear. We confirm the influence of the major modes of climate variability, planetary circulation patterns, and the changes in cyclonic activity in the variability of moisture transport to the Arctic. We reaffirm that the effect of moisture transport on the Arctic SIE through changes in humidity, cloud cover, and precipitation over the Arctic is a complex scientific problem that requires further detailed study over the decades to come, and we propose some important challenges for future research. This article is categorized under: Paleoclimates and Current Trends > Modern Climate Change
