DESCRIPTION

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 Ferrell cells) is discussed quantitatively to provide a description of planetary-scale motions.

CLASS POLICIES
Class Communications
All class announcements, readings/reading lists, homework assignments, solution sets, visuals shown in class and other materials will be posted on the class Angel website (https://cms.psu.edu/section/default.asp?id=201516FAUP___RMETEO421_001&ts=1440251304).

It is your responsibility to keep up to date with all deadlines and other class arrangements and information provided there.
Class-related emails must be sent through Angel.
All official communications from Penn State are sent to students' Penn State e-mail
accounts. Be sure to check your Penn State account regularly, or forward your Penn
State e-mail to your preferred e-mail account, so you don't miss any important
information.
Cell Phone Policy: Please silence your cell phone in the classroom or office hours and
do not use it.
Academic Integrity
Academic honesty is required and expected of everyone in this class.
This course adopts the EMS Academic Integrity Policy
http://www.ems.psu.edu/current_undergrad_students/academics/integrity_policy.
I expect all submitted work to be your own. Feel free to discuss homework assignments
with others, but never, ever (I really mean it) copy another’s work. Homework is not a
collaborative project. Students in this class are expected to complete all of their
homework and quizzes individually, to complete the exams on their own, and to write
their papers in their own words using proper citations. Students must not copy exam
answers from another person's paper and present them as their own; students must not
plagiarize text from papers written by others.
If it appears that there is copying on any of the formal class assessments (homework, quiz, exam,
paper), I will begin the formal Disciplinary Action Procedure as outlined by our college
(http://www.ems.psu.edu/current_undergrad_students/academics/integrity_policy).
Students presenting other people's work as their own will (at minimum) earn zero on
the assignment or exam. Academic dishonesty may result in an F or XF in the course.
I derive no joy from this process; it protects the integrity of your grades, and ultimately,
of your degree. Thankfully, the need for its use is very rare in our department.
If you are unclear on any aspect of this policy, consult me immediately.

Accommodations for students with disabilities
Penn State and your course leaders welcome students with disabilities. The Office for
Disability Services (ODS, http://equity.psu.edu/ods) website has contact information
for every Penn State campus: (http://equity.psu.edu/ods/dcl).
In order to receive consideration for reasonable accommodations, you must contact the
University Park disability services office, participate in an intake interview, and provide
appropriate documentation (http://equity.psu.edu/ods/guidelines). If this assessment
supports your request for reasonable accommodations, the disability services office will
provide you with an accommodation letter.
Please make an appointment as quickly as possible to share this letter with your instructor and
TAs and to discuss the recommended accommodations with us.
You must follow this process for every semester that you request accommodations.

Students who become ill or sustain an injury should use their best judgment on whether
or not they are well enough to attend class. According to the university Illness
Verification Policy: http://studentaffairs.psu.edu/health/welcome/illnessVerification/,
students with minor illness or injury (less than a week absent from class) are not
required to secure the signature of medical personnel, however a student may be asked
to produce a medical certificate for absences that persist for more than a week.
Students encountering serious family, health, or personal situations that result in
extended absences should contact the Office of Student and Family Services for help:
http://studentaffairs.psu.edu/familyservices/.
Whenever possible, students participating in University-approved activities should
submit to the instructor a Class Absence Form available from the Registrar's Office:
http://www.registrar.psu.edu/student_forms/, at least one week prior to the activity.
Military Personnel
Veterans and currently serving military personnel and/or spouses with unique
circumstances (e.g., upcoming deployments, drill/duty requirements, disabilities, VA
appointments, etc.) are welcome and encouraged to communicate these, in advance if
possible, to the instructor if any special arrangements for class need to be made.
Campus emergencies (including weather delays) and personal safety alerts
Campus emergencies and personal safety alerts, including weather delays, are
announced on Penn State News: http:/news.psu.edu/ and communicated to cellphones,
email, the Penn State Facebook page, and Twitter via PSUAlert. If you have not already
done so, consider signing up for PSUAlert at https://psualert.psu.edu/psualert/.
REQUIRED TEXTBOOK:
Holton, J. R. and G. J. Hakim, 2013. An Introduction to Dynamic Meteorology, 5th
Edition, Elsevier Academic Press, 532 pp., ISBN 978-0-12-384866.
The text is on reserve in the EMS library, but you are encouraged to purchase this or
another Dynamic Meteorology textbook. I am happy to talk with you about other
options.
There are a few additional required readings from other sources; these will be made
available to you via the class Angel site.
Readings are assigned for each topic as shown in the detailed class schedule. Finish the
week’s readings by the end of the day each Friday so that you can complete an online
quiz (see below) on time.
Recent research has demonstrated that taking notes and working through derivations
using pencil/pen and paper will help you retain the material in the readings most
effectively.

such as e-mail and bulletin board postings. Netiquette covers not only rules to maintain
civility in discussions, but also special guidelines unique to the electronic nature of
forum messages. Please review Virginia Shea's "The Core Rules of Netiquette"
(http://www.albion.com/netiquette/corerules.html) for general guidelines that should
be followed when communicating in this course.
ASSESSMENT
Your overall class grade will be calculated from all of the assessment materials (see
below) using the following weighting: 20% homework, 65% exams, 10% quizzes, 5%
based upon my subjective assessment of the effort you demonstrate to me and to the
TAs in class and during office hours.
Quizzes
Weekly quizzes will be given online (via Angel); no quizzes will be given during exam
weeks. Quizzes will be available no later than Thursday and must be completed by Friday.
Each quiz will comprise about 10-20 multiple-choice questions based on the readings and
some lecture material. These quizzes are open book but they must be taken alone and must
represent solely your own work. You will be given 45 minutes to take each quiz.
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 by me. Homework assignments are equally weighted. Homework will
be graded by one of the TAs and returned on the following Monday.

Exams
There will be two equally weighted midterm exams [20%, 20%] and a final [25%];
75 minutes is allocated to each exam, but the exams are designed to take less than 1 hour.
Exams will be closed book; no notes, books, crib sheets or calculators are 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 September 24 and November 5 (both
Thursdays). There will be no class on the day after these exams. All exams are
cumulative, although typically they will emphasize the materials covered since the
previous exam. I will provide you details on time and location for the final exam as
soon as I know them.
Any makeup exams will be administered as oral exams.
TAs will not be expected to hold additional office hours leading up to exams – they are
students too.
Final Grades
Your final grade will be the rounded sum of all of the assessments described [none of
these will be “dropped”]. Once the numeric grade has been calculated, letter grades will
be assigned as follows
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%.
Deferred Grades
If you are prevented from completing this course within the prescribed amount of time,
it is possible to have the grade deferred with the concurrence of the instructor. To seek a
deferred grade, you must submit a written request (by e-mail or U.S. post) to your
instructor describing the reason(s) for the request. It is up to your instructor to
determine whether or not you will be permitted to receive a deferred grade. If, for any
reason, the course work for the deferred grade is not complete by the assigned time, a
grade of "F" will be automatically entered on your transcript.
Disclaimer Statement
Please note that the specifics of this Course Syllabus can be changed at any time, and
you will be responsible for abiding by any such changes. Changes will be posted to the
course discussion forum.
