AOS 201C Spring 2017 Geophysical Turbulence Jim McWilliams This is an advanced graduate dynamics course offered in Spring, 2017. Its contents are the following: Types of Atmospheric and Oceanic Turbulence Some Good Turbulence Books Turbulent Flows: General Properties 3D Homogeneous Turbulence 2D Homogeneous Turbulence Shear Turbulence Convective Turbulence Stably Stratified Turbulence Planetary Boundary Layer Turbulence Geostrophic Turbulence The format is twice weekly lectures at 12:30-2 on Tuesdays and Thursdays in Mathematical Sciences Building 7121, based on written lecture notes and other materials available at http://web.atmos.ucla.edu/~jcm/turbulence_course_notes/ (with updates made as we go along). The best way to participate is to read the lecture notes ahead of time so that the class time can focus on a combination of highlights of my choice and student questions or comments. There are no formal prerequisites although a good knowledge of fluid dynamics is necessary. The course is easy in that there is no homework or exams, although classroom alertness is expected and there is a term project with a written paper and class presentation. The course is hard in that its subject matter is the extensive, mature literature on experimental results and conceptual frameworks for what has been called the last important unsolved problem of classical physics, as well as the unclaimed Clay Millennium Prize on proof or disproof of the existence and smoothness of solutions of the Navier-Stokes equations. (This gives you a flavor of the course.) I would prefer all students who do not need a grade for this course for their graduation to take it S/U. For those who need a grade, it will be based on class participation and the term project paper and presentation.
