8A Extreme Precipitation II

Tuesday, 30 January 2024: 4:30 PM-6:00 PM
318/319 (The Baltimore Convention Center)
Hosts: (Joint between the 38th Conference on Hydrology; and the 37th Conference on Climate Variability and Change )
Chairs:
Kelly M. Mahoney and Sarah M. Trojniak, NOAA, College Park, MD
Cochairs:
Kenneth E. Kunkel, NCEI, Center for Weather and Climate, Asheville, NC and John W. Nielsen-Gammon, Texas A&M University, Atmospheric Sciences, College Station, TX

This session invites papers on all aspects of extreme precipitation, including atmospheric river (AR) events, convective storms, hurricanes, typhoons, extreme snowfall events, their relationship to floods, and hydrologic impacts. Possible topics include observations (e.g., rain gauge networks, ground-based radar, satellite retrievals, multi-sensor fusion, etc.), modeling, exploration of key physical processes, short-term and seasonal prediction, orographic and elevation-based relationships, climate change, and risk assessment. Papers exploring the causes and consequences of individual extreme precipitation events that cause floods or terminate droughts, details of the relationship between extreme precipitation and flooding, extreme snowfall accumulation and melt, as well as key factors that inform decisions around changing extreme precipitation and flood risk are particularly encouraged.

Submitters: Kelly M. Mahoney, Earth System Research Laboratories/ Physical Sciences Laboratory, NOAA, BOULDER, CO; Kenneth E. Kunkel, North Carolina Institute for Climate Studies, North Carolina State Univ., Asheville, NC and John W. Nielsen-Gammon, Atmospheric Sciences, Texas A&M Univ., College Station, TX
