The Climate and Energy Systems (CES) Statistical Analysis working group is evaluating trends and variability in long-term historical hydro-climatological timeseries, such as precipitation and streamflow, to determine if the effects of climate change are already found in these data. Comparisons are also made with expected future trends, based on simulated timeseries from climate scenarios. Patterns of large-scale atmospheric circulation and weather types, both in the past and in the future are also being studied. The emphasis in this project is on changes in the occurrence of extreme events, such as floods and droughts. An increased risk of flooding may have adverse consequences for dam safety, and these implications are also being analysed using flood frequency analysis of historical and scenario data.
