🌪️ Happy to share this new paper from @mktippett.bsky.social and I. We constructed a synthetic event set for U.S. tornado outbreaks. It has 200,000+++ events, which can be boiled down to resolve localized risk, and we detect robust shifts in activity due to ENSO and trends.

A Global Ensemble Forecast System (GEFS)-based synthetic event set of U.S. tornado outbreaks
Abstract. Severe convective storms (SCS) are important drivers of global insured losses, and tornado outbreaks – when many tornadoes occur within a short time span – cause extreme and localized loss o...

I usually include NOAA NCEI billion-dollar weather/climate disaster figures in my talks. Over the last couple months, I've spent extra time highlighting who makes them and why it's so valuable, including "while we still have this data..." to convey my worry. Sadly I guess my fears were warranted.

The canceled grands are shock and awe, but the real damage will come from the long-term (massive) reductions in funding to the entire US research ecosystem and the defunding of entire fields and initiatives for training, growing, and diversifying the research workforce.
