"Hailstorms in a changing climate" - seminar by Dr Tim Raupach
It is our great pleasure to announce the seminar "Hailstorms in a changing climate" by Dr Tim Raupach from UNSW Sydney Climate Change Research Centre, and ARC Centre of Excellence for Climate Extremes. It will take place on July 6th, 2023 in GR A1 402.
Hailstorms cause significant damage worldwide, yet their changes in a warming climate remain uncertain. In this presentation I will give a short overview of the current state of knowledge about hail and climate change, before showing results from my recent work using an improved hail proxy to look at changes in hail frequency with time. In the first study, we used the hail proxy applied to reanalysis data to examine trends in hail frequency for the last four decades across Australia, a continent with high hail damage potential in some of its most populous areas. The resulting pattern of trends was verified by comparison with radar observations. In the second study, we used the verified hail proxy applied to global simulations to examine changes in hail frequency by degree of global warming for multiple models, to provide unified global estimates of possible future changes in hail frequency.
