Summary:<!--!introduction!--> Rapid Arctic warming has altered the regional hydrological cycle through reduction in Arctic sea ice. Observational and modeling efforts provided evidence that the enhanced evaporation from the Arctic Ocean could lead to changes in hydrological cycle over high latitude terrestrial zones. However, its amount and temporal variations from seasonal to decadal timescales need further investigations with attention to the moisture source regions. This study, thus, developed atmospheric moisture transport model that is driven by reanalysis dataset as forcing, and investigated the moisture exchange across the Arctic coastal regions. Atmospheric moisture that originated from Arctic Ocean evaporation has increased significantly in autumn to early winter during 1981–2019 when substantial sea ice retreat was observed. The enhanced Arctic moisture content is found in western Siberia in September. In the Arctic region, the fraction of atmospheric moisture originated from Eurasian and North ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
