Scientia Senior Lecturer at UNSW Sydney Institute for Climate Risk and Response. I study severe storms, especially hail, in a changing climate ⛈️. I also take photos and climb mountains. These views are my own. https://timraupach.com
We’re coming to the end of a big week
of storm science as #ECSS2025 wraps up. Here Boris Blanc presents his work on interannual variability in hailstorms in Australian cities. Boris is doing a PhD with me at UNSW. An impressive audience present for the last session!

Had a great poster session at #ECSS2025 with plenty of fruitful discussions. Tanya Patel, who I’m supervising for a PhD, presented her work on land-ocean lightning contrast in the Australian tropics. I showed downscaling-based hail size projections for Australian cities.

I’m very happy to be in Utrecht, The Netherlands, for the 12th European Conference on Severe Storms #ECSS2025 run by @essl-ecss.bsky.social and supported by @knmi.nl and @eumetsat.int. Here, @pietergroenemeijer.bsky.social opens the conference. Lots of exciting science to discuss this week!
