In a new study @NatureComms, we show that diabatic heating strengthens ridge blocks, while it dampens dipole blocks in the Northern Hemisphere. It all depends on their shape. Led by PhD student @zhaoyu_liu @PurdueEAPS. Thanks @USCLIVAR blocking workshop. nature.com/articles/s41467-0…

Blocking diversity causes distinct roles of diabatic heating in the Northern Hemisphere

Nature Communications - Atmospheric blocking patterns are often categorized into several types and diabatic heating is thought to primarily contribute positively to blocks. Here, the authors show...

Happy to be able to link deep-time paleoclimate directly to our present-day and future climates. Let's make paleoclimate more "useful"! With @PaleoOcng @leiwqg and others. eos.org/research-spotlights/…

Paleoclimate Patterns Offer Hints About Future Warming - Eos

A new study examines 10 million years of sea surface temperature data to offer predictions about how future warming may unfold.

Our recent paper on Nature Geoscience, led by my PhD student Vincent Sassard. This study reveals slab tearing along subducted oceanic plate joints, define as the intersection of oceanic plates from different spreading centers. @PurdueEAPS @PurdueScience nature.com/articles/s41561-0…

Slab tearing along a subducted oceanic plate joint beneath the Alaska Peninsula

Nature Geoscience - An oceanic plate joint, where two sets of plate fabrics intersect, may have led to weakening, tearing and a window opening in the slab subducting beneath the Alaska Peninsula,...

Can AI weather models predict out-of-distribution gray swan extremes? We report @PNASNews that the answer is NO for global gray swans, YES for regional ones: AI models can't extrapolate but can learn from similar events in other regions during training! doi.org/10.1073/pnas.2420914…

Can AI weather models predict out-of-distribution gray swan tropical cyclones? | PNAS

Predicting gray swan weather extremes, which are possible but so rare that they are absent from the training dataset, is a major concern for AI wea...

Like many university faculty, I write a lot of reference letters. Here's instructions I give to students. Students: many of these practices will make your letters better, improve your relationship with your mentors, and convey more professional behavior. drive.google.com/file/d/1Q-o…
