Former NOAA scientist Kirk Bryan, Ph.D, has been named winner of the 2023 National Academy of Science’s Alexander Agassiz Medal for his pioneering work in oceanography and climate science.
You may have heard of atmospheric rivers in the news lately due to the intense rainfall and flooding along the U.S. West Coast. These naturally occurring air currents can bring both severe disruption and great benefit through the heavy rain and mountain snows that contribute to regional water supply. NOAA studies atmospheric rivers to improve forecasting capabilities as well as to improve our understanding of atmospheric river impacts on communities and the physical environment.
