[Justin Cooke @JustinPCooke]

Excited to share that my work was published today in PNAS! This project, with my advisor (George I. Park) and @dougsjunkdrawer, looks to explore how the turbulent structure of an ABL changes when it encounters a roughness transition. Read about it here

Conveners: Justin Cooke (GSO), Xiao Ge (TAMU), Marco Larrañaga (FSU), and Eileen Hofmann (ODU)

Please feel free to share with colleagues that may be interested, and to reach out if you have any questions! We hope to see you in New Orleans!

Call for Abstracts!

We are excited to announce our session titled: "Understanding Gulf Ocean Systems: Advances in Improving Ocean Circulation Forecast Skill" (AGU-OS028) at this year's AGU Fall Meeting in New Orleans (Dec. 15-19).

[Justin Cooke @JustinPCooke]

The session will provide a forum for contributions that enable improved operational forecast skill of Gulf circulation with a focus on applications.

Submit your abstract by July 30, 2025

Yeah. Not good.

Every team in the @MLB uses a specific mud harvested from an undisclosed river site in New Jersey to better grip new balls. A study of the mud explores how similar materials could help tires grip muddy roads and provide insight into mudslides. In PNAS:

[Justin Cooke @JustinPCooke]

In two weeks, I will be presenting at #APSDFD a scaling for turbulent flows encountering a roughness transition. This work was born out of a question by @ArratiaPaulo during my defense, and has led to some very interesting results!

[Justin Cooke @JustinPCooke]

Together, with George Park and @dougsjunkdrawer, we use our prior LES work and two experimental datasets to show the existence of a new, robust outer-scaling for internal boundary layers which works for a wide variety of flow regimes and roughness transition types.

Had a great time at the UGOS Annual Meeting at Texas A&M! Definitely a great way to dive head first into what’s going on in oceanographic research for my new postdoc position!

[Doug Jerolmack @dougsjunkdrawer]

@pradeep_shravan publishes a breathtaking paper on understanding soft earth suspensions:https://t.co/uoy5M6kjIF with me and of course work spouse @ArratiaPaulo .
using just sand, clay and water he is able to reproduce the full range of observed debris flow rheologies!

[Justin Cooke @JustinPCooke]

The IBL influences where the longest and strongest of these motions occurs within, with implications for the transport of sediment.

[Justin Cooke @JustinPCooke]

My work with @dougsjunkdrawer showed how the internal boundary layer height is a critical length-scale in atmospheric flows, but why?

We follow this work by observing changes to the turbulence producing motions and find that the IBL height sets the largest length-scales!

[Justin Cooke @JustinPCooke]

Great write-up about our recently published work with @dougsjunkdrawer!!

[Penn Engineering @PennEngineers]

In a new paper published in @PNASNews, Penn Engineers led by Justin Cooke, a doctoral student at @MEAM_Penn, have uncovered an unexpected universal pattern in how turbulent airflows behave over natural dune fields. https://t.co/nCHSSqnyqN

[Mechanical Engineering and Applied Mechanics, Penn @MEAM_Penn]

Congratulations Dr. @JustinPCooke for successfully defending his PhD dissertation, "Computational Study on Rough Wall-Bounded Flows and their Effects at Low and Very-High Reynolds Numbers" under the advisory of MEAM Asst. Professor George Park. 🎉
