General Circulation of the Atmosphere (EAPS 53600)
Hypothesis-driven graduate-level (or advanced UG) course that trains students on the basic theories governing the large-scale circulations in our atmosphere, from the jet stream to the Madden-Julian Oscillation. Students learn by testing hypotheses using theory, data, simple computer models, and rotating tank experiments. Students then develop from scratch and test their own hypothesis as part of a semester-long final project. Taught: Spring 2018, Spring 2020.
Course text: Vallis Essentials (2019), Hartmann (2017)
Course notes/materials: Spring 2020 (switched to virtual recorded lectures for Lectures 11+ due to Covid-19; links to individual videos + notes below, or full youtube playlist here. If you'd like the original powerpoint file send me an email and I can share them.)
I decided to share these publicly because a) I am so grateful when I find content that others have created before when prepping my own classes, and b) these advanced topics had almost nothing of the sort available online. So hopefully this will help someone else out.
