What effects the large scale circulation of the atmosphere? Like the antiquated heating system of a New York apartment, solar radiation unevenly warms the Earth, leading to gradients in energy in both altitude and latitude. But unlike the simple convection of air in your drafty home, the effects of rotation, stratification, and moisture lead to exotic variations in weather and climate, giving us something to chat about over morning coffee … and occasionally bringing modern life to a standstill.
The goals of this course are to describe and understand the processes that govern atmospheric fluid flow, from the Hadley cells of the tropical troposphere to the polar night jet of the extratropical stratosphere, and to prepare you for research in the climate sciences. Building on the foundation in Geophysical Fluid Dynamics, we will explore how stratification and rotation regulate the atmosphere’s response to gradients in heat and moisture. Much of our work will be to explain the zonal mean circulation of the atmosphere, but in order to accomplish this we’ll need to learn a great deal about deviations from the zonal mean: eddies and waves. It turns out that eddies and waves, planetary, synoptic (weather system size) and smaller in scale, are the primary drivers of the zonal mean circulation.
There will also be a significant numerical modeling component to the course. You will learn how to run atmospheric models on NYU’s High Performance Computing facility, and then design and conduct experiments to test the theory developed in class for a final course project. A new focus this year is to make our science reproducible, learning best practices for future research.
