Analysis and Attribution of Changes in Siberian Hydroclimate and Implications for the Future

This work will document observed changes in the hydroclimatology of the Siberian region, attribute these changes to specific physical mechanisms in the context of climate change, and study the impact of those changes from the regional to the hemispheric weather and climate. The project will use observational analysis and modeling experiments to investigate the links between arctic sea ice trends and changes to seasonal snow cover. The autumn snow cover is of particular interest due to its persistent increases over the last two decades despite the robust warming trend and its connection to stratosphere- troposphere coupling and hemispheric variability in the subsequent winter season.

*This project is funded is through a National Science Foundation OPP-ARC grant. It is included with the CSAS projects because it has a strong seasonality focus and is closely aligned with this group of funded projects.
