Brief course description from University Bulletin 

This four-credit course, required of all meteorology majors, builds on the foundation laid in METEO 300, Fundamentals of Atmospheric Science, by applying the equations of motion to a variety of atmospheric phenomena. The intrinsically rotational aspects of large-scale atmospheric motions are presented through a discussion of vorticity dynamics (including both relative and planetary vorticity) and the related circulation theorems of Kelvin and Bjerknes, which culminate in potential vorticity thinking. The contrast between oscillating and unstable atmospheric systems is highlighted using the examples of gravitational, inertial, and shear instability, and the parcel and perturbation methods are introduced for studying these systems. An introduction to wave dynamics presents the concepts of phase and group velocity with applications to gravity, inertial, and Rossby waves, and to geostrophic adjustment. Finally, the general circulation, including the major zonal wind systems (e.g., the mid-latitude westerlies) and the major overturning cells (Hadley and Ferrel cells) is discussed quantitatively to provide a description of planetary-scale motions. 

Additional details on course description: We will also discuss one journal article, Johnson et al. (2014), co-authored by Steven Feldstein. The purpose for reading one journal article is to familiarize students with the method by which scientists communicate the results from their research, for students to see how journal articles are structured, and for students to know how to find journal articles.

Course Policies 

CLASS STRUCTURE: Lectures will be on Monday, Wednesday, and Friday. The recitation period will be on Thursday and will be used to work on a detailed exercise that is generally not collected or graded, though sometimes parts of it get added to the next homework assignment. 

HOMEWORK:  Homework assignments will be given every Wednesday (except during exam weeks) and due on the following Wednesday at the beginning of class. Late homework will not be accepted unless there are extenuating circumstances (e.g., illness) and prior approval has been granted. Homework assignments are equally weighted. Homework will be graded by the TA and returned on the following Monday.  

QUIZZES: There will be weekly equally weighted quizzes posted online (via Canvas) Friday to be completed by Sunday, except during exam weeks. About 10-20 multiple-choice questions will be given on the readings and some lecture material. These quizzes are open book but they must be taken alone. You will be given 45 minutes to take each quiz. If you are unable to take a quiz because of extenuating circumstances, please let me know ahead of time and we will schedule a makeup. 

EXAMS: There will be three equally weighted exams, each lasting about two hours. Exams will be closed book with no crib sheets or calculators allowed. You are expected to be able to do simple arithmetic (include manipulating powers of 10) to 1 or 2 significant figures. The first two exams are tentatively scheduled for 7:00-9:00PM, September 21 and November 2 (both Thursdays). There will be no class on the days of and days after these exams. The third exam is during finals week and is not cumulative. Details on time and location will be given to you as soon as I know them. We will also have a review session on the class period just before the exam. If you are unable to take an exam because of extenuating circumstances, please let me know ahead of time and we will schedule a makeup. 

GRADES: 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%. Weighting: 20% homework, 70% exams, 10% quizzes. 5% extra credit is based on my subjective assessment of the effort you demonstrate to me and the TA in class and during office hours. 

CURVING POLICY: For the exams, a curve will be applied if class average is below 80.

LATE PENALTY: For homework assignments, a 10% penalty will be applied for each day. 

Academic integrity statement 

Students in this class are expected to write up their problem sets individually, to work the exams on their own, and to write their papers in their own words using proper citations.  Class members may work on the problem sets in groups, but then each student must write up the answers separately.  Students are not to copy problem or exam answers from another person's paper and present them as their own; students may not plagiarize text from papers or websites written by others.  Students who present other people's work as their own will receive at least a 0 on the assignment and may well receive an F or XF in the course.  Please see: Earth and Mineral Sciences Academic Integrity Policy: http://www.ems.psu.edu/undergraduate/academic-advising/forms-and-procedures/academic-integrity, which this course adopts.
