Advancing the Understanding of Changes in Precipitation Intensities at the Subdaily Time Step Posters


Submit an Abstract to this Session


Session ID#: 51256

Session Description:
Extreme precipitation events pose many questions related to flood risks, infrastructure design, agriculture sustainability, water supply for human consumption and ecosystem functioning, among others. There is strong evidence that precipitation intensities at the daily time step have been increasing in a warmer climate, and are expected to continue in the future, however the research on sub-daily observed precipitation intensities is limited or restricted to model simulations. This session seeks contributions from research, operational, and user communities that use sub-daily precipitation intensities with the aim of understanding their changes and developing new approaches to adapt and design the existing and future infrastructure under non-stationary climate conditions. In particular: 1) climate uncertainty under non-stationary conditions; 2) design storms and hydrologic risk associated with storm’s uncertainty, modelling and uncertainty analysis at sub-daily time scales; 3) design approaches to incorporate non-stationary in flood managing risk; and 4) next-generation Intensity Duration Frequency (IDF) curves.
