During the past decade, the study of global climate change has emerged as one of the most pressing and important scientific disciplines of the current era. This interdisciplinary course for math and physics students is an introduction to the scientific and mathematical foundations of climate science. Topics include the green house effect, atmospheric thermodynamics, radiative transfer, and fluid dynamics. Simple mathematical models will be developed for various coupled components of the climate system, such as plane parallel models of the atmosphere and radiative transfer, onedimensional icealbedo models, models of heat transfer between ocean and atmosphere, and possibly models incorporating two horizontal dimensions. Because of the interdisciplinary nature of the course, it will be largely selfcontained; physical principles and mathematical techniques will be carefully explained. Students may enroll for this course either through Math 625 or Phys 595 CL.

Class Meetings 
Mondays & Wednesdays, 5:00 to 6:15 p.m., Chaparral Hall 5117 
Grading 
There will be two midterm exams, each worth100 points, and a final exam worth 200 points. Collected homework, cumulatively, will contribute up to 100 points. Plus grades (+) and minus grades (–) will be assigned for this course. The dates of the midterms will be announced in class. 5 bonus points may be earned for each Climate Seminar presentation attended.
Final Exam: Wednesday, May 14, 2014, 5:30 PM  7:30 PM 
Textbook 
An Introduction to Atmospheric Physics, Second Edition (2010) by David G. Andrews. This will serve primarily as a reference for the lectures. Additional references will be made available.
