METEO 470

Climate Dynamics

Climate Dynamics (METEO 470, 3 credits) 

Instructor: Michael E. Mann, Department of Meteorology, 514 Walker Building, mann@psu.edu (office hours: Wed 1:00-2:15 PM) 

TA: Yuting He, 413 Walker Building,  yzh120@psu.edu  (office hours: Mon 2:00-3:30 PM) 

Meeting Time/Place: Tu/Th 10:35-11:50 AM (214 Hammond) 

Office Hours: You are encouraged to use email for questions when possible. You are welcome to visit my office for questions during scheduled office hours (Wed 1:00-2:15 PM), or by appointment. 

Motivation:

In order to under and model the climate system, we need to understand the balance of energy within the climate system as well as the dynamics of the underlying components of the climate system, including the atmosphere and ocean, and the mechanisms by which these components may be coupled. Topics discussed will include global energy balance, including zero and one-dimensional models of radiative equilibrium, the role of the ocean circulation including the thermohaline and wind-driven components, the El Nino/Southern Oscillation (ENSO), internal and forced climate variability, and climate change. 

Prerequisites: Meteo 300, Meteo 421, and Meteo 431

You are expected to be familiar with the governing equations (momentum and energy conservation, continuity, and equation of state) of the atmosphere on a sphere.

It is also assumed that you have satisfied the statistics requirement for the Meteorology major and therefore are familiar with basic statistical concepts including linear regression. 

Webpage

We will regularly draw upon the course homepage as a resource for the course:

http://www.meteo.psu.edu/~mann/Mann/courses/METEO470SPR18/index.html

Aside from links to the course syllabus, there will be links to the readings, problem sets, slides from the lectures, and other course-related materials. 

Lectures

Attendance of all lectures is expected. You are strongly encouraged to ask questions and participate constructively in class. Copies of slides from the lectures will usually be made available electronically through the course website before or shortly following the lecture. 

Textbook

There is no required textbook. Some students might find Peixoto & Oort “Physics of Climate” a useful reference (it has been placed on reserve in the EMS library).

Supplementary readings from various sources will be posted on the course website. 

Grading

Problem Sets (50%): There will be 5 problem sets assigned that will involve applications of topics covered in class.  You may discuss the problems with each other, but the problem set you turn in should reflect your own individual effort. We will frequently make use MATLAB for assignments (MATLAB is available on the Meteorology Computer Lab Computers)

Mid-Term Exam (20%): There will be an in-class mid-term examination roughly mid-way through the semester (Feb 23).

Final Exam (30%): There will a final examination for the course at the scheduled time and date. 

Grade Scale: A: 92-100%; A-: 88-91%; B+: 84-87%; B: 80-83%; B-: 75-79%; C+: 71-74%; C: 63-70%; D: 50-62%; F: <50%
