The goal of this effort is to dramatically improve precipitation forecasts in terms of accuracy, extent in time, and reliability. The challenge demands investment across the value chain from basic understanding of precipitation processes and predictability limits, to enhanced observations, data assimilation, improved models, post-processing and tools for the human forecaster, culminating in understandable, actionable, and equitable services -- these services being informed by stakeholder engagement. Thus, it is a grand Research-to-Operations challenge.
An initial suite of projects have kicked off. These initial projects and early results will be highlighted. However, to address the ongoing climate crisis, a ‘all-hands-on-deck’ approach is required to build climate resilience through advanced precipitation prediction. The strategy to achieve this result will be described, with attention focused on opportunities for community involvement.
