Per NOAA/AOML/HRD’s Sim Aberson, the 219 kt reading will be the fastest wind ever measured by a dropsonde if it passes final quality-control checks.
This is hands down the most extraordinary dropsonde in Atlantic recon history.

ICYMI: NSF has followed through with its plan to end the lease on its Antarctic icebreaker, many years before necessary, with almost no congressional pushback. Now there's a mad scramble to fill the gap with less capable ships. @science.org's Jeff Mervis followed the story up:

This is the second part of the work we covered here, highlighting that CO2 is the dominant forcer in temperature and sea level changes during ice age cycles.
(It's also a great chance for others to cover; this has not been widely reported. There's even an old ice core now that can test this!)

Every climate model out there has a different AMOC sensitivity to the relatively freshwater introduced by the pacific water flowing in to the North Atlantic (it’s about a psu less).
But wait - how does that scale with the freshwater input by arctic rivers. (Half as important PI) -

A lot of people are being misled by that paper. They separate the continents into areas getting dryer or wetter -- but then only emphasize the dry while leaving out how the wetter areas are subtracting from SLR.

NSF won't renew the funding for an academic center squarely focused on AI for weather forecasting, located right in the heart of US weather research in Oklahoma. (Notably, AI2ES was funded and created under the first Trump administration.)
This is AI2ES, my AI institute. No way around it other than to say this is really awful. We are doing so many amazing things! We want to keep doing amazing things but without this level of funding, we will not be able to do so.
Another blow to meteorological R&D this morning, as it was confirmed that NSF is terminating funding for its main weather and earth science focused AI research institute led by the Univ. of Oklahoma. Also - a LOT of weather to talk about, especially in the West. More: https://tinyurl.com/mr2znbdb
