Enrollment policy. 

Students who do not meet the prerequisites may be dis-enrolled during the first 10-day free add-drop period after being informed in writing by the instructor (see:  If you have not completed the listed prerequisites, then consult with the instructor.  Students who re-enroll after being dis-enrolled according to this policy are in violation of the Student Code of Conduct (

  1. Required: A set of color pencils
  2. Optional Texts (on reserve in the EMS library):
  • Midlatitude Synoptic Meteorology: Dynamics, Analysis, and Forecasting, by Gary Lackmann (American Meteorological Society, 2011)
  • Mid-latitude Weather Systems, by Toby Carlson

Course Objectives:

  1. To demonstrate skills for the analysis of synoptic-scale surface and upper-air observations of the atmosphere.
  2. To demonstrate familiarity with the principles underlying the structure, development, and evolution of synoptic-scale weather systems.

Course Outcomes:

  1. To demonstrate knowledge of the Norwegian cyclone model and its use as a conceptual framework for the analysis of atmospheric structure at the synoptic scale.

  2. To demonstrate knowledge of the methods for determining vertical motion in the atmosphere qualitatively.

  3. To demonstrate knowledge of the role of the upper-level flow (e.g., the jet stream) in the development of extratropical cyclones.

  4. To demonstrate the ability to apply quasi-geostrophic theory to the development and evolution of fronts and extratropical cyclones

Class Notes & Web:

I often place lecture materials on ANGEL prior to class. Printing these materials before class will greatly facilitate your note-taking. Lecture notes will be the main resource for this course, along with information gleaned from laboratory exercises and map discussions.  I will frequently use  and, of course, the Penn State e-wall

Assessment Tools:

There will be a quiz in lab on Fridays except the weeks of the exams. There will be no make-up quizzes, but I’ll drop your lowest quiz grade. The exams will be given in class on Thursday February 20 and Thursday April 10.  The final exam will be scheduled by the university during finals week.

Also, there will be numerous laboratory assignments (on the order of one per week) and you will always have at least two days to complete a lab. There will be an immediate 25% penalty for any lab handed in late, a 50% penalty after six hours, and no credit will be given for labs handed in more than 24 hours late.  Neatness, organization, technical soundness, spelling and grammar are important!  You may work together on the labs, but the work you submit must be uniquely your own (see Academic Integrity policy).

You will also be required to participate in two weather briefings during the semester and do at least one online module (details to come).  The weather briefings will be worth (cumulatively) 8% of your final grade, while each online tutorial will count as one lab.


The weighting of the components of your course grade is as follows:

  • 14%  Exam 1
  • 14%  Exam 2
  • 24%  Final Exam
  • 10%  Quizzes
  • 25%  Labs
  • 8%  Weather Briefings   
  •  5%  Participation/Attendance**

**Active, thoughtful contributions to class discussions (both in lecture and lab) are expected and will be translated into a contribution of between 0 and 5% to your overall course grade. This course abides by the Penn State Class Attendance policy given at  Basically, I assume you’re in class unless you have a really good excuse to miss, and you’re responsible for all that you miss.

Academic integrity.  For information about the EMS Integrity Policy, which this course adopts, see:

Here’s a brief interpretation of that integrity policy, as it applies specifically to this course:  You may never copy answers from another person and present them as your own.  This applies to quizzes, exams, and problem sets.  You are allowed to discuss the problem sets with other students, but the work you turn in must be your own, in your own words.  Suspicion of copying on problem sets will result in an immediate 50% reduction for the first offense, and an F for the course on the second offense.  Cheating on exams or quizzes will result in an immediate F for the course.

Instructor’s Philosophy:

This course is intended to provide a solid foundation for you to apply to forecasting.  As an outlet for aspiring forecasters, there will be an optional forecasting contest beginning mid-semester.  Top finishers will be awarded points on their final grade (details forthcoming).  Also, if you are interested in forecasting, you should participate in WxChallenge, the National Forecasting Contest (which PSU won last year)

Regardless of your interest in forecasting, we will talk about the day-to-day weather in this class.  Therefore, I recommend you spend a few minutes each day at the electronic map wall, immersing yourself in the weather – past, present, and future.

“The principle task of any meteorological institution of education and research must be to bridge the gap between the mathematician and the practical man, that is, to make the weather man realize the value of a modest theoretical education and induce the theoretical man to take an occasional glance at the weather map.” Carl Gustav Rossby 1934
