Hurricane #Barbara has become the first hurricane of the 2025 Eastern Pacific season 🌀
Barbara is located southwest of Mexico and is moving northwest. It is near peak intensity but is expected to weaken and dissipate in the coming days.
Hot take. The government isn’t subsidizing university budgets. Universities are lending subsidized expertise to research and development that contributes to the public good. It’s called partnership.
How do a climate-scale patterns, like La Niña, influence extreme weather events, like tornado outbreaks? I break it down in this ENSO Blog post, plus discuss this hyperactive 2025 season in particular. 🌪️
New paper! 📣
More positive and less variable North Atlantic Oscillation at high CO2 forcing
led by Ivan Mitevski (Princeton), with me, Gabe Vecchi (Princeton), Clara Orbe (NASA GISS), and Lorenzo Polvani (@climate.columbia.edu)

🌧️📉 Can we predict tropical cyclone precipitation (TCP) at subseasonal scales? Our new study shows that biases in TC occurrence forecasts limit skill in TCP (and total rainfall too!)

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.
NEW: NOAA retires its widely cited billion-dollar weather and climate database amid staff cuts. Unique database had been tallying disaster costs for 45 years. www.cnn.com/2025/05/08/c...
Qué buena oscilación! (QBO)
Great to have a post up with @seasonedchaos.bsky.social.
Read about one of the less known, yet better behaved, oscillations in the climate system and how it impacts our surface conditions.
How QBO affects weather/climate patterns can be confusing, but @jorgelgf.bsky.social tries to break down the main QBO teleconnection routes in this post. As usual, we had fun with graphics... here's an animated schematic:
