Forschungsschwerpunkt

My post-doctoral research focuses on the subseasonal clustering of European extreme precipitation events and its relationship to large-scale atmospheric drivers. Extreme precipitation events that occur in close succession can have important societal and economic repercussions. Few studies have investigated the link between large-scale atmospheric drivers and temporal clustering of extreme precipitation events on a sub-seasonal scale. In a first step, we use 40 years of reanalysis data (ERA-5) to investigate the link between possibly influential atmospheric variables and the temporal clustering of catchment-averaged extreme rainfall events in Europe. We define extreme events as exceedances above the 99th percentile where runs of consecutive days are declustered. We then explicitly model the seasonal rate of extreme occurrences using penalized cubic splines. The smoothed seasonal rate of extremes is then used to (i) infer the significance of subseasonal clustering and (ii) serves as the baseline rate for the subsequent modelling step. We use a Poisson Generalized Additive Model (GAM) to model the relationship between the temporal clustering and predictor variables, such as the North Atlantic Oscillation, the Arctic Oscillation, atmospheric blocks and the R-metric.
