Climate Extremes: Patterns, Mechanisms, and Attribution II


Submit an Abstract to this Session


Session ID#: 58891

Session Description:
Extreme water cycle events such as droughts and floods represent the greatest impacts of climate variability and change on the coupled energy-water-land systems, and consequently on our environment and society. Thus, understanding and predicting single and compound extreme events related to the water cycle is critical for securing water, energy, and food supply and for effective decision-making. However, this presents significant scientific challenges due to gaps in mechanistic understanding, limitations in modeling approaches, and lack of observations. This session invites contributions that advance understanding of water cycle extremes from weather to climate timescales and/or their impacts on the coupled energy-water-land systems, including theoretical research, data analysis, numerical modeling, and/or data-model integration. This session also welcomes studies in relevant areas such as convection processes and modeling, impacts of climate variability and change on water cycle extremes, surface/subsurface water interactions, managed and unmanaged ecosystems, and environmental and societal impacts of extreme events.
