Oceanic Fluid Dynamics CEE/EESS 363F (Offered in Fall 2017; Spring 2012, 2011, 2009)

The fundamental dynamics of rotating stratified fluids with application to oceanic flows. Topics include inertia-gravity waves, geostrophic and cyclogeostrophic balance, vorticity and potential vorticity dynamics, quasi-geostrophic motions, planetary and topographic Rossby waves, inertial, symmetric, barotropic, and baroclinic instability, Ekman layers, and the frictional spin-down of geostrophic flows.

Advanced Topics in Geophysical Fluid Dynamics CEE/EESS 364F (Autumn 2012)

A seminar-style class covering the classic papers on the theory of the large-scale ocean circulation. Topics include: wind-driven gyres, mesoscale eddies and geostrophic turbulence, eddy-driven recirculation gyres, homogenization of potential vorticity, the ventilated thermocline, subduction, and the abyssal circulation.

Atmosphere, Ocean, and Climate Dynamics: The Atmospheric Circulation EESS 146A/246A, EARTHSYS 146A/246A, GEOPHYS 146A/246A (Winter 2017, 2016, 2015, 2014, 2013, 2011)

Introduction to the physics governing the circulation of the atmosphere and ocean and their control on climate with emphasis on the atmospheric circulation. Topics include the global energy balance, the greenhouse effect, the vertical and meridional structure of the atmosphere, dry and moist convection, the equations of motion for the atmosphere and ocean, including the effects of rotation, and the poleward transport of heat by the large-scale atmospheric circulation and storm systems.

Atmosphere, Ocean, and Climate Dynamics: The Ocean Circulation EESS 146B/246B, EARTHSYS 146B/246B, GEOPHYS 146B/246B (Offered in Spring 2018; Spring 2017, 2016, 2015, 2014, 2012, 2011, 2010)

Introduction to the physics governing the circulation of the atmosphere and ocean and their control on climate with emphasis on the large-scale ocean circulation. This course will give an overview of the structure and dynamics of the major ocean current systems that contribute to the meridional overturning circulation, the transport of heat, salt, and biogeochemical tracers, and the regulation of climate. Topics include the tropical ocean circulation, the wind-driven gyres and western boundary currents, the thermohaline circulation, the Antarctic Circumpolar Current, water mass formation, atmosphere-ocean coupling, and climate variability.

Earth System Dynamics EESS 215 (Spring 2010) Co-taught with Noah Diffenbaugh, Chris Field and Eric Lambin

An introductory graduate-level course emphasizing qualitative understanding of key components of the earth system (lithosphere, hydrosphere/oceans, biogeochemistry, biosphere, atmosphere, humans, climate change) at the regional-to-global scale, and the mass, energy, and momentum transport processes that govern dynamics with and between these system components. Governing equations will be presented but a qualitative process understanding and graduate-level Earth System literacy will be emphasized.
