Coupling Climate and Hydrologic Models for Regional Hydroclimate Insights: Advances in Downscaling, Integration, and Decision-Relevant Applications
Session ID#: 249532
Session Description:
As global climate models (GCMs) improve in representing large-scale processes, their coarse resolution remains a key limitation for regional planning in hydrology, water resources, and climate risk management. Downscaling, statistical, dynamical, or hybrid, is essential to translate global projections into decision-relevant information. This session invites contributions at the climate-hydrology interface, especially those using coupled or interactive modeling at regional scales. We welcome studies that: (1) develop innovative statistical, machine learning, or hybrid techniques for spatial refinement, bias correction, and uncertainty analysis; (2) apply regional climate and hydrologic model frameworks; (3) evaluate hydroclimate dynamics and extremes in complex terrain; and (4) integrate downscaled information into decision-making, including co-produced metrics with impacted groups. This session fosters cross-disciplinary exchange, bridging the gap between large-scale projections and local information needs. We aim to highlight diverse approaches and real-world applications that improve the usability and impact of downscaled climate data for adaptation and preparedness.
