| Session Description | As acknowledged by the Intergovernmental Panel on Climate Change (IPCC) Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation, anthropogenic climate change is projected to cause changes in climate and hydrological extremes through changes in frequency and duration, spatial extent and the intensity of events. Regional climate modelling and downscaling can provide some answers to the types of changes expected but there are still questions as to the ability of climate models to represent the temporal and spatial patterns of observed extremes. In addition, for some processes there remain uncertainties in the analysis of observations, particularly in terms of optimum methods for explaining spatial and temporal variability. This session aims to bring together research on climate and hydrologic extremes to examine the following issues: 1) Evaluation of regional climate models and downscaling methods to reproduce observed extremes 2) Spatial and temporal models for representing extremes 3) Compound extremes, where extreme impacts are produced by several climatic extremes acting simultaneously or in close succession 4) Novel approaches for carrying out studies on adaptation or impact assessments for climate or hydrological extremes |
