H23F:
Hydrometeorological Forecasting of Atmospheric Rivers and Their Impacts: Models, Methods, and Observations I Posters

Submit an Abstract to this Session



Session ID#: 26815

Session Description:
Atmospheric rivers (ARs) are a major driver of floods, water resources and hydroclimate variability in many regions of the world, such as western North America. Reliable forecasting of precipitation, streamflow, soil moisture, snowfall and other impacts of ARs requires integrated observations and models of the coupled atmosphere, ocean and land systems. This session highlights recent developments in forecasting and observing the hydrometeorological impacts of ARs. Specific focus areas include coupled atmospheric-hydrologic modeling for streamflow prediction during ARs; impacts of ARs on modeled or observed water resources; evaluations of AR forecast skill and its impacts on operation of reservoirs and other infrastructure; near real-time data assimilation and parameter estimation techniques to improve forecasts; sensitivity of AR forecast skill to physical processes in the land-ocean-atmosphere system; comparisons of new forecasting tools with existing methods; and the use of forecasts in flood risk management and ecological and regulatory issues related to ARs.
