Summary: Seasonal Streamflow Forecasts for the Hydrologic Unit Code (HUC-8) Basins in
North Carolina utilizing Multimodel Climate Forecasts
Investigators: Sankarasubramanian Arumugam and Ryan Boyles (State Climate Office of NC)
Four specific objectives are encompassed in the proposed study:
Objective 1: Assemble precipitation forecasts from multiple General Circulation Models (GCMs)
and Regional Climate Models (RCMs) available from various research and national agencies and
analyze their potential ability to predict seasonal streamflow variability in HUC-8 basins.
Objective 2: Statistically downscale the precipitation forecasts available from GCMs and RCMs
and optimally combine them to develop seasonal streamflow forecasts for the HUC-8 basins.
Objective 3: Update the streamflow forecasts every month during the winter and summer seasons
using the monthly updated climate forecasts issued from national centers.
Objective 4: Disseminate both retrospective and real-time streamflow forecasts developed for the
winter and summer seasons through the NC Climate Retrieval and Observations network Of the
Southeast (NC CRONOS) database.
