Bill > S322

This bill aims to improve atmospheric river (AR) forecasting in the United States by establishing a comprehensive improvement program through the National Oceanic and Atmospheric Administration (NOAA). The program focuses on enhancing forecast accuracy, lead time, and communication of atmospheric rivers, which are narrow bands of concentrated moisture in the atmosphere that can cause significant precipitation and potential flooding. Key provisions include developing advanced forecast skill metrics, creating a unified forecast system with improved modeling capabilities, advancing scientific understanding of ARs, developing better tools for predicting AR landfalls, and enhancing research-to-operations transitions. The bill mandates innovative observations using various technologies like radar, aircraft, satellite measurements, and ocean buoys, and requires improved modeling for precipitation forecasts, especially in complex terrain. Additionally, the program will invest in atmospheric river reconnaissance by acquiring and sustaining crewed and uncrewed aircraft for observations, establishing observatories along the West Coast, and developing robust data management strategies. The bill also emphasizes improving hazard communication by developing methods to categorize AR intensity, creating best practices for regional communication, and exploring strategies to help the public understand the varying impacts of atmospheric rivers. Within 270 days of enactment, the Under Secretary must develop and publicly share a detailed program plan outlining research, development, and technology transfer activities.
