5B Extreme Precipitation III

Tuesday, 14 January 2025: 8:30 AM-10:00 AM
210 (New Orleans Ernest N. Morial Convention Center)
Host: 39th Conference on Hydrology
Cochairs:
John W. Nielsen-Gammon, Texas A&M University, Atmospheric Sciences, College Station, TX; Sarah Marie Trojniak and Victor A. Gensini, PhD, CCM, CIMMS, Department of Earth, Atmospheric, and Planetary Sciences, Norman, OK

This session invites papers on all aspects of extreme precipitation, including atmospheric river (AR) events, convective storms, hurricanes, typhoons, and extreme snowfall events, as well as their relationship to floods and hydrologic impacts. Possible topics include observations (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; John W. Nielsen-Gammon, Atmospheric Sciences, Texas A&M Univ., College Station, TX; Sarah Marie Trojniak, Systems Research Group, NOAA/NWS/WPC/HMT, College Park, MD and Victor A. Gensini, PhD, CCM, Earth, Atmosphere, and Environment, Northern Illinois Univ., Dekalb, IL
