Extremely excited to announce that I am the incoming chair for the AMS AI STAC Committee! Looking forward to leading our committee alongside @zhonghuazheng.bsky.social and @tropmetpie.bsky.social We are seeking new members to join the AI STAC, including both regular and student members.

I am so excited to announce that one of the radar meteorology courses that I developed with @comet-meted.bsky.social is now available! "Dual-Polarization Fundamentals" picks up where "Weather Radar Fundamentals" left off! learn.meted.ucar.edu#/online-cour... (Register on learn.meted.ucar.edu first.)

Checking my bkuesky feed this week/month/year.

I've released autumnplot-gl v4.0! New features: - Station plots - Support for globe view in Maplibre (Mapbox is in progress) - Support for mutiple colormaps on a contour fill plot (precipitation type, for example) - A few performance optimizations github.com/tsupinie/aut...

I finally read computer scientist Joseph Weizenbaum’s 1976 classic “Computer Power and Human Reason.” This book deserves a massive revival in our current age of grotesque and largely thoughtless AI creep into everything:

Numerical weather prediction models (ECMWF IFS) still outperform AI weather models in forecasting record-breaking hot and cold extremes and unseen wind extremes Preprint arxiv.org/abs/2508.15724 with Zhongwei Zhang @erichfischer.bsky.social @zscheischlerjak.bsky.social and Sebastian Engelke

5. Today I read a paper by @sabinaleonelli.bsky.social and Alexander Mussgnug that I think illustrates this point perfectly. philsci-archive.pitt.edu/24891/1/Phil...

🎤 BOOM: Federal judge just ruled to *reinstate* the suspended ~300 NSF grants at UCLA. Determines that NSF violated the previous court order by attempting to swap "termination" with "suspension". storage.courtlistener.com/recap/gov.us...

Do not get on this internet on the 20th anniversary of Katrina and rehabilitate George Bush I swear to god.

PSA: the wind components in the GFS and GEFS cube sphere tile netCDF files are already in Earth-relative coordinates. Figured this out by making this plot after two days of wondering why the transformed wind vectors wouldn't line up across tiles.

🎉🎉 SO proud of our Summer'25 REU students + Momentum Fellows who presented their research at the 2025 Summer Student Conference Poster Session in Boulder, CO! 🎉🎉

Right then... A quick review of the DOE's new 'critical review' of climate science. Whether it's worth a formal community response - I'm still not sure, but here's my first thoughts /thread/

#Breaking: Just got off the phone with a NOAA spokesperson. DOD has stated that SSMIS microwave scans will be made available to NOAA through the end of the satellites’ lifespan and until the replacement instrument’s data comes online.

After many months of work by numerous team members at NSSL and OSTI, the Warn-on-Forecast System transition to the NOAA VLab environment is now complete! Day 1 and there's potential for widespread significant severe weather in the northern Plains today. Forecasts here: cbwofs.vlab.noaa.gov/Forecast

With Tom Lehrer's passing, I suppose this is a moment to share the story of the prank he played on the National Security Agency, and how it went undiscovered for nearly 60 years.

Update on my GFS variable deep dive: I found comments in a Fortran file defining most of the variables and providing units for some of them: github.com/NOAA-EMC/fv3...

SCOOP: Two senior NOAA officials were just placed on leave. Both led ‘Sharpiegate’ inquiry www.cnn.com/2025/07/25/w...

Pinging again. So far no answers.

Do any of my NOAA colleagues know where the GFS/GEFS cube sphere variable metadata (long names, units) is documented? The netCDF files lack any metadata and the variable names are somewhat cryptic.

I woke up this morning with a map thought in my head, and here it is:

NEW: New: Trump administration to proceed with groundbreaking flash flood risk database following media covg. this week. Contracts had been under review for about a month, raising suspicions it was being held up due to climate change content. (1/2)

Great reporting from @emorwee.bsky.social open.substack.com/pub/heated/p...

The discourse surrounding precipitation changes in a warming climate (both public discussion and even scientific one at times) is complicated by widespread conflation of changes in averages vs extremes (and also actual vs *potential* evaporation/evaporative demand). [Thread]

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Moran on NASA: 'bill reflects and ambitious approach to space exploration' prioritizes Artemis, rejects termination of SLS and Orion before alternatives are available.' on NOAA: 'this bill recognizes that importance. NOAA is funded in a way that eliminates RIFs at NWS.'

Senate committee on appropriations markup meeting is starting now. They'll be discussing a lot of stuff, but in particular, science agencies like NSF & NASA. Yesterday Sen. Moran indicated funding would be 33.9 billion, preserving FY '24 numbers. www.appropriations.senate.gov/hearings/ful...

🧪 BREAKING (good news): Senate subcommittee says NO! to Trump's proposed slashes to NASA & NSF funding. Today, the subcommittee said to keep NASA + NSF funding at $33.9 billion, the same as in FY24. See 7:15 below. Full Senate appropriations committee meets tomorrow about it. 🧵 1/3

I'm quoted in NBC News giving a shoutout to MRMS and the FLASH model developed by my threatened friends at NSSL and CIWRO. www.nbcnews.com/science/envi...

Hearing today (7/9) on the 16-state AG case against NSF grant terminations & indirect rates. We may see another prelim injunction (or even final judgment) soon after. But any reinstating grants would likely be limited to plaintiffs: CA, CT, CO, DE, HI, IL, MA, MD, NJ, NV, NM, NY, OR, RI, WA, WI

I heard a rumor that AIRS on NASA Aqua is being turned off on Oct. 1. Does anyone on there know what the impact on weather forecasting? I seem to remember seeing an analysis a while back that assimilating AIRS data drove big improvements in forecasts.

I hope a journalist on the climate beat will report on this - this may be only one piece of the general awfulness that is happening to federal science, but the NOAA Climate and Global Change Fellowship has trained many of the current leaders in weather and climate: cpaess.ucar.edu/cgc/current-...

The House Science Committee postponed a hearing on “Protecting Lives and Property: Harnessing Innovative Technologies to Enhance Weather Forecasting” that was scheduled for tomorrow morning and featured the Texas State Climatologist. science.house.gov/hearings?Con...

As of today, all current NOAA Climate and Global Change postdoctoral fellows have been furloughed due to the Dept of Commerce not releasing the funding for the program. In addition no new Fellows were awarded this year. cpaess.ucar.edu/cgc

One big missing piece in the flooding discussion is what the Kerr County Sheriff's office was doing Thursday night. Why didn’t they have cops posted along the river watching for flooding or drive up and down the highway blaring their sirens and PA systems?

It's been a bit since I've done a meteorological deep dive, but the devastating flash #flood in central Texas this July 4th/5th deserve a closer look. #TXwx Yes remnants of #Barry were involved helping enhance moisture. A remnant MCV from Mexico on 3 July also played a role. Full evolution below ⤵️

The House Appropriations Committee won't take up the CJS spending bill (which includes NASA, NOAA, and NSF) next week as previously scheduled. "Due to scheduling changes, those proceedings will be rescheduled to a later date," TBD. appropriations.house.gov/news/press-r...

For those looking for the National Climate Assessments: NCA5 (2023): repository.library.noaa.gov/view/noaa/61... NCA4 vol. 1 (2017): repository.library.noaa.gov/view/noaa/19... NCA4 vol. 2 (2018): repository.library.noaa.gov/view/noaa/19... NCA3 (2014): repository.library.noaa.gov/view/noaa/19...

🧪 Science folks: There are two *separate* budget battles 1️⃣ Almost over: The Big Bullshit Bill But now faces new opposition in the House (gift NYT link below—calling your House reps *right now* matters) 2️⃣ Just starting: FY26 appropriations Next week will be a big week for NSF. 🧵 1/3

Update to 30 (cont). Here’s a recent snapshot of globalchange.gov: globalchange.govarchive.us And for kicks, here’s the earliest snapshot: web.archive.org/web/20000815...

The administration's plan for FY26 is to move forward with the President's budget request framework if a vanilla continuing resolution is passed at the end of September. We will need to encourage Congress to pass a law to prevent closures of labs and CIs or include language in the CR preventing it.

Startling conclusion here: www.smbc-comics.com/comic/humanity #smbc

The left better start figuring out how to weaponize today's decision rather than just (rightfully) criticizing it. - Go back into Judge Kaczmaryk's court to dissolve all of his nationwide orders. - Pass gun bans and insist any order applies only to plaintiffs.

Good news: A source says NOAA has renewed its cooperative institute with Princeton, which supports GFDL, its world-class weather and climate modeling center. Funding was set to expire on June 30. Following a trend, Commerce Sec Lutnick approved the renewal at the last minute.

Beyond today's annexation of the NSF building, this new budget detail in WaPo is also 🤯 and needs investigation: "So far this year, [NSF] has received only $6.5 billion of the congressionally appropriated $9 billion that it is supposed to spend on research" www.washingtonpost.com/business/202...

🧪 Russ Vought, a Project 2025 architect, is currently withholding $2.5 billion from NSF's budget for this year. This move is: -Illegally secretive -Unusual and suspect -Disrupts science -Subverts Congress It's also urgent because the *fiscal* year ends Sept 30 (call your rep). 🧵 Let's unpack...

Does anyone want to train an AI NAMulator? AI models can replicate your favorite biases and you can run it on your beefy laptop/gaming computer

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years. NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Our first paper on the CREDIT AI weather prediction framework is now published in npj Climate and Atmospheric Science! Updated paper includes comparisons with pangu and more details about the model. Check it out at www.nature.com/articles/s41...

A good summary of the latest saga on what they continue to do to us (months and months later)... 😩 www.reddit.com/r/NOAA/comme...

BREAKING: Judge denies NSF's 15% indirect rate plan. Like the DOE and NIH attempts, it too has now been rejected by courts. storage.courtlistener.com/recap/gov.us...
