An interdisciplinary approach to the study of extreme weather events: Large-scale atmospheric controls and insights from dynamical systems theory and statistical mechanics

The workshop on 'Large-Scale Atmospheric Controls of Extreme Weather Events and Novel Predictability Pathways' gathered speakers with a wide range of backgrounds to foster such cross-disciplinary interactions. A specific focus was on identifying novel analysis techniques to describe large-scale atmospheric flows and their links to extreme weather events. Tim Woollings analyzed the eddy-driven jet stream's variability on daily to decadal time scales. He showed a complex interplay between these time scales, with decadal variations in jet speed modulating the shorter-term variability in the jet's latitudinal location. Lynn McMurdie focused in more detail on intense precipitation events associated with extratropical cyclones.
