Abrupt Changes and Extreme events - Assessment and Risks
Convenors
Ray Bradley, Pierre Francus, Manfred Mudelsee
Description
Abrupt changes and extreme events are recorded in many natural archives of climate. This session welcomes contributions illustrating how the intensity and the speed of abrupt changes, and the frequency and magnitude of extreme events can be recognised, dated and quantified in order to provide an assessment of their frequency and relationship to forcing factors.
Contributions using annually resolved archives are particularly relevant when their analysis yields rates of change and recurrence estimates. We also welcome contributions about statistical approaches used to define the concept of "abrupt changes" and "extreme events" in a useful way for society and stake holders.
