Active Learning With the Thermal Wind

The thermal wind is a foundational concept in synoptic and dynamic meteorology. It couples geostrophic and hydrostatic balances into an elegant description of the relationship between horizontal temperature gradients and vertical wind shear, with direct application to the analysis of temperature advection. However, in the experience of the authors, it is also a topic that challenges students in these subjects. During a session at the 10th NAGT Earth Educators' Rendezvous in July 2024, we devised and created a physical model analog to demonstrate and explain the thermal wind using everyday office materials, including three-ring binders and the top of a coffee cup. In this presentation we will physically demonstrate this model; relate it to the thermal wind; discuss multiple extensions; and present qualitative and quantitative results of employing this model in courses at the introductory and upper-level undergraduate levels.
