One of the major challenges for the current and future climate diagnostics is the occurrence of very rare, but extreme intense precipitation events. Those record-shattering events lead to the Valencia-Flood in October 2024 in Spain or the Ahr-floods in July 2021 in Germany with billions of Euro of financial losses and unfortunately significant numbers of fatalities (cf. e.g., Leckebusch & McCarthy (2026) and references therein). While the principal underlying physical mechanism of precipitation formation and the principal mechanisms of necessary precursor conditions are well understood, the exact amount of extreme precipitation and when and where those events may occur are less well understood. The same holds true for the principal rate of occurrence, which is difficult to estimate as those events may occur only once or twice per century in the current climate. Even more difficult is an assessment of those events for future climate conditions, altered by human activities. We can already diagnose that those events are more likely to occur under the influence of a warming climate, but the exact changes in those statistics of their occurrence remains a challenge. One of the reasons for this is the inability of current climate models to fully simulate those rare and extreme precipitation events in their full characteristics, from very local scale processes to the wider statistical occurrences for e.g., 30-years climatic time spans. This project will develop and test a novel approach to estimate those rare events. It will investigate whether a combination of AI- and Extreme Value Theory (EVT)-approaches can produce reliable estimates for future climate states. Thus, can AI–EVT models trained on reanalyses and large hindcast ensembles estimate regional extreme-rainfall distributions that remain reliable when transferred between global warming levels and circulation regimes? This project would best suit a student with a Computer Science background, or otherwise a numerical background for example Meteorology, Physics, or Maths, with experience coding in Python or similar (e.g. R, Matlab), and preferably with some experience in AI approaches.
