UPDATE: New MS/PhD student opportunities!

The Convective Storm Dynamics group is recruiting to fill multiple new GRA positions to begin in Fall 2024 either at M.S. or Ph.D. levels.

One GRA position focused on studying the nature and governing mechanisms of deep convective organization in the context of the Atlantic ITCZ. This position entails spending ~one month in the tropical Atlantic during the Aug-Sept 2024 PICCOLO (Process Investigation of Clouds and Convective Organization over the atLantic Ocean) field campaign.

One GRA position focused on examining tropical convective-scale dynamics. Supported by the National Science Foundation.

Two GRA positions (tied to multiple School of Meteorology research groups) to study the interaction between the tropics/poles and midlatitudes to advance our understanding of blocking events. Supported by the Department of Energy.

New publication from the CSD group! 👀

Curious about the influence of midlevel shear on supercell behavior? Look no further than this paper now out in JAS early online release, led by Andrew Muehr, junior undergraduate of our group:

Muehr, A. J., J. H. Ruppert, Jr., M. D. Flournoy, J. M. Peters, 2023: The Influence of Midlevel Shear and Horizontal Rotors on Supercell Updraft Dynamics. J. Atmos. Sci., DOI: 10.1175/JAS-D-23-0082.1

Major congratulations to Andrew on his first pub!

Fun in the sun with Coriolis

How does Coriolis deflection work? Shouldn’t projectile motion follow a straight path? If not, then how, when, and why not? Today we grappled with these questions in James’s Atmospheric Dynamics 1 (METR 3113) class by taking advantage of the phenomenal weather on a late-summer day in Norman. The idea: one volunteer moves across the human circle following a straight path (to their perception) while the surrounding people walk out the path of the circle.

The mind-bending insight: to the rotating viewers (akin to people residing on Earth, in the rotating reference frame), the path is curved, while someone standing still in or outside the circle simply sees a straight path. 🤯 🤯

Major shoutouts to 1) Jon Aurnou and the DIYnamics crew for inspiration for this activity at the Earth Educators’ Rendezvous 2023, and 2) OU student Parker Davis for volunteering to take these photos!
