This course is a quantitative discussion of the physical properties of earth materials and dynamic processes in the solid Earth. We will closely follow Geodynamics by Turcotte & Schubert, in covering topics in stress and strain, elasticity and texure, heat transfer, gravity, fluid mechanics, rock rheology, and crustal faulting as mechanisms and consequences of plate tectonics.
Volcanic eruptions are the surface expression of the transfer of mass and volatiles from the deep interior of the planet. Violent eruptions rapidly transform the landscape and impact the atmosphere on short timescales, and the integrated history of magmatism has played a central role in the production of the crust and the degassing history of the planet. The fluid dynamics of volcanoes span a vast array of phenomena from viscous magma flows to turbulent, multiphase eruptions. This course will trace the path of magmas from their ultimate source in the mantle, storage and evolution in the crust, through eruption at the surface where they interact with the landscape and atmosphere.
This course will explore the interaction of the solar wind with the Earth's magnetosphere using a combination spacecraft observations and fundamental plasma physics. Credit not allowed for both EAS 4360 and EAS 6360.
Application of fundamental principles of chemistry to understanding the critical factors controlling the levels and distributions of atmospheric trace gases and their variation in time.
Presents experimental and field methods through a focus on measurements of atmospheric gases and particulates associated with poor air quality. Experiments will involve laboratory measurements and an air quality field experiment on the order of 1-week duration.
This course is an advanced introduction to environmental data analysis and intended for first year graduate students. The goal of this class is to provide a deeper understanding of the theories and applications underlying the statistical analysis of environmental data, both in the space, time and spectral domain, and to provide the students with a hands-on experience. Ideally in the end of this class you will have developed a series of computer programming tool boxes and theoretical skills that should immediately be available for analyzing and modeling data in your own research. Although some preview knowledge of probability and statistics is required, a background review will be provided. Concepts and notation will be reintroduced as needed. In this class you will learn (a) how to combine models, which quantify statistical or dynamical relationships with observations (b) time series analysis, (c) forecasting and extrapolation, and (d) signal decomposition.
An introduction to the fundamental concepts underlying our current understanding of atmospheric fluid dynamics and its relation to mid latitude weather processes. The course includes both a theoretical component and a synoptic meteorology component focusing on meteorological data, observational analyses, large-scale weather systems, mid latitude cyclone development, and numerical weather prediction.
An introduction to the use of geophysical fluid dynamics in describing and modeling the atmosphere.
Ocean-atmosphere interaction in the tropics. The scales will range from local, through regional to global. The emphasis is on physical aspects of interaction and the modeling of these processes. Exercises will be set each week using a variety of models, ranging from one-dimensional mixed layer models to general circulation models.
EAS 4655 or EAS 6502
An introduction to the phenomenology and dynamics of large-scale atmospheric variations having time scales of a week and longer. Using papers from the recent scientific literature and real-time analyses, we will overview the basic characteristics, underlying physics, and current status of a number of large-scale atmospheric phenomena. Topics will include weather regimes, storm track variability, stratospheric polar vortex variability, El Nino-Southern Oscillation, teleconnections, monsoon circulations, the Arctic and Quasi-Biennial Oscillations, and stratosphere-troposphere coupling. The class format will include reading assignments and student presentations.
