Introduction
Susanna Mohr is currently working at the Institute of Meteorology and Climate Research, Karlsruhe Institute of Technology. Susanna's research is in meteorology and climatology with a focus on (1) meteorological extreme events (mainly thunderstorms, hail), (2) hazard assessment and statistical analysis of such events, (3) their interaction in the context of climate change and natural climate variability, and (4) their scale interaction with the large-scale atmospheric processes.

On March 28, 2025 at 6:20 a.m. UTC, a major earthquake with the magnitude 7.7 occurred near the capital city of Sagaing, Myanmar, at a depth of 10 kilometers. The earthquake was felt across much of Myanmar and in neighboring Bangladesh, India, China, and Thailand. It is estimated that up to 222.4 million people experienced the earthquake. While mos...

Europe frequently experiences a wide range of extreme events and natural hazards, including heatwaves, extreme precipitation, droughts, cold spells, windstorms, and storm surges. Many of these events do not occur as single extreme events but rather show a multivariate character, known as compound events. We investigate the interactions between extr...

Based on lightning measurements in western and central Europe from 2001 to 2021 (May–August), a grid-based climatology and trend analysis of thunderstorm activity has been developed. The results indicate a significant decrease in thunderstorm activity in many regions. Extending the analysis beyond a purely grid-based approach, areas with spatio-tem...
