Overall,these studies highlight the diversity of research on extremes and the number o challenges faced – but also the potential rewards yielded – in bridging the gaps across the disciplines contributing to this field (e.g. statistics, climate model- ing, process-based a nalyses). They also point to the range of topics that need to be considered in meeting the WCRP Grand Challenge on Extremes and in developing our capability to interpret extreme events with confidence, ranging from the fundamental data, to analysis techniques and the framing of questions, and to the supporting process understanding. In the years to come, and building (among others) upon this collection of articles, we expect that major advances can be reached from furthering such interactions.
