ABSTRACT:

Researches have reported important changes in water cycle components of the northern hydrology system. This presentation will review and synthesize recent progress in the hydrology research of arctic large rivers and describe an array of results, including discharge and heat flux regimes, impact of climate change and human influence, precipitation data and bias-corrections for observational errors, snow cover variation and its relationship to streamflow dynamics, and validations of remote sensing snow cover products across the northern regions/watersheds. We will identify key gaps in the northern hydrology research, and discuss the future research needs and directions. Arctic rivers are the dynamic component of the global climate system. Arctic hydrologic systems exhibit large temporal variability due to changes in large-scale atmospheric circulation and poleward moisture transport. This variation significantly influences the cross-shelf movement of water, heat, nutrients, and sediments.
