Earth System Models for seasonal to centennial predictions and projections at regional to global scales.
NOAA will improve the skill of seasonal forecasts and delivery of information products (e.g., predictions, projections) for decadal to centennial time scales with quantified uncertainties. Additionally, NOAA will improve regional outlooks through downscaling approaches, high-resolution global climate model runs, multi-model ensembles, and better representation of key physical and biogeochemical processes, including ocean dynamics, with specification and quantification of uncertainties. Failing to fill the various modeling gaps in key physical and biogeochemical processes risks leaving decision makers with insufficient scientific support concerning future climate states. Improved information will enable decision makers to properly address regional and local planning for the impacts of flooding and drought, declining air quality, siting of critical infrastructure in coastal communities, and managing natural resources with changing conditions of our oceans and other ecosystems.
