Brief course description from University Bulletin: This course is designed for graduate students interested in numerical weather prediction.  The objective of this course is to provide the student with an overview of the assumptions used in the parameterization of sub-grid scale processes and how these assumptions may influence numerical forecasts of the weather.  Various well-known parameterization schemes will be reviewed and discussed in class. 

Prerequisites and concurrent courses: None 

Required textbook: Parameterization Schemes: Keys to Understanding Numerical Weather Prediction Models by David Stensrud.  A copy of the textbook is on reserve in the College of Earth and Mineral Sciences Library.

  • Students can identify the most common approaches to physical process parameterization and recognize strengths and weaknesses to these approaches.

Course Outcomes:

  • Students can read the parameterization literature effectively, having a strong foundation in how these schemes operate and common assumptions.
  • Students can compare physical process parameterization schemes and understand similarities and differences.
  • Students can select schemes for use in numerical weather prediction and climate models wisely.

Grading: The grading scheme for this course is: 45% problem sets, 15% mid-term exam, 15% final exam, 15% paper review and presentation, and 10% class participation.  Assuming 100 points total, students with 90 and above will get an A, 80 and above will get a B, and 70 and above will get a C.  See the instructor at least a week ahead of time if you have a conflict with an exam. 

Grading Policy: All assignments are due at the end of the class period on the day assigned. No credit will be given for late assignments.  Exceptions may be given for emergency situations after consultation with the instructor. 

Problem Sets: There will be a total of 9 problem sets assigned during the semester. Each problem set has been developed to expand upon topics covered in class and several of them will require the students to write computer programs. Since the instructor is familiar with the FORTRAN programming language, using this language in your programming assignments is encouraged, but not required. Assistance in writing code in other programming languages is not available.

Paper Review: Each student will choose a paper related to numerical weather prediction and/or parameterization and write a formal review of the paper. The journal article must be approved by the instructor in advance by 8 September. The written review should be no more than 2 pages in length. The student will also present a summary of the paper, including their overall evaluation of the quality of the paper, to the class.  These presentations will be conference style, so the student will have 12 minutes to summarize the work and 3 minutes for questions.  Presentations should be prepared using Microsoft Powerpoint and either email to Dr. Stensrud ahead of time or brought to class on a memory stick. 

Mid-term examination: A mid-term examination is scheduled for 19 October and will cover material presented during the lectures, reading assignments, and homework from the beginning of the semester through the material in Chapter 5. 

Final examination: A final examination is scheduled during finals week, and will cover all the material presented during the semester, although weighted towards materials covered since the mid-term. 

Class participation: Each student is expected to participate in class by attending lectures on time, asking questions, and answering questions from the instructor.

You must follow this process for every semester that you request accommodations.

Attendance: This course abides by the Penn State Attendance Policy E-11:, and Conflict Exam Policy 44-35: Please also see Illness Verification Policy:, and Religious Observance Policy: Students who miss class for legitimate reasons will be given a reasonable opportunity to make up missed work, including exams and quizzes.  Students are not required to secure the signature of medical personnel in the case of illness or injury and should use their best judgment on whether they are well enough to attend class or not; the University Health Center will not provide medical verification for minor illnesses or injuries. Other legitimate reasons for missing class include religious observance, military service, family emergencies, regularly scheduled university-approved curricular or extracurricular activities, and post-graduate, career-related interviews when there is no opportunity for students to re-schedule these opportunities (such as employment and graduate school final interviews).  Students who encounter serious family, health, or personal situations that result in extended absences should contact the Office of Student and Family Services for help:  Whenever possible, students participating in University-approved activities should submit to the instructor a Class Absence Form available from the Registrar's Office:, at least one week prior to the activity.

Weather Delays: Campus emergencies, including weather delays, are announced on Penn State News and communicated to cell phones, email, the Penn State Facebook page, and Twitter via PSUAlert (Sign up at:

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.

Penn State E-mail Accounts: 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.

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 Angel and discussed in class.
