Course Description:

Techniques for understanding and analyzing synoptic-scale weather situations, with an introduction to weather forecasting.
Required Materials: A set of colored pencils
Required textbooks: None
Recommended textbook (on reserve in the EMS library):
Midlatitude Synoptic Meteorology: Dynamics, Analysis, and Forecasting, by Gary Lackmann (American Meteorological Society, 2011)
Internet materials and links: ANGEL

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


Meteorology Prerequisite: Meteo 101 or Meteo 201 or Meteo 200A/B
Mathematics Prerequisite: Math 230 or Math 231 (Vector Calculus)
Prerequisite or Concurrent: Meteo 421 (Dynamics), Meteo 431 (Thermodynamics)

Note: Meteo 411 is a required course for all undergraduate Meteorology majors.

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. 


“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

Synoptic meteorology is the essential link between dynamical meteorology and weather forecasting, theory and applications, mathematics and weather maps.  It is foundational for interpreting weather observations and numerical weather prediction model output. It provides the fundamental conceptual insights to the structure and evolution of mid-latitude weather systems, which are linked to nearly all other aspects of atmospheric science at all scales. 

Students should expect to immerse themselves in following the day-to-day weather.  A great resource for this is the Penn State E-Wall (
Aspiring forecasters may wish to participate in WxChallenge, the National Forecasting Contest.

Assessment Tools:

Required written/oral assignments

There will be numerous synoptic laboratory assignments, which will typically be given out during the first half of the week, and will be due at the end of the lab session on Friday (11 am).  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 after the start of the next class.  Professor maintains the right to decline acceptance of a late assignment beyond a certain time.  Neatness, organization, technical soundness, spelling and grammar are important.  While students may consult with their classmates on these assignments, the final product should represent the student’s own work.

Each student (either individually, or as a team) will be required to orally present a weather briefing / forecast discussion to the class.  These are around 10-15 minutes in length, and will describe recent weather events and forecasts through the context of the concepts learned in class.  The faculty will provide examples of these during the early part of the semester.

Examination Policy

Weekly quizzes will be given each Friday (except during exam weeks) during the lab session. These will cover topics recently covered in class lectures or the laboratory exercises, and are good practice for the exams.  There will be no make-up quizzes, although the lowest quiz grade will be dropped.

Two midterms and one final exam will be given.  These will be closed-book, individual written assessments.

Grading Policy

  • Exam 1 - 20%
  • Exam 2 - 20%
  • Final Exam - 25%
  • Quizzes - 10%

  • Attendance / Participation - 5%

Attendance and Participation: Students are required to attend class (both lectures and labs) and participate in all exercises.  Active, thoughtful contributions to class discussions are encouraged.

Lecture notes will often be placed on ANGEL (, although students are ultimately responsible for their own note-taking.  It is reasonable that material covered during lectures, through laboratory exercises, and in forecast discussions may appear on quizzes and tests.  Reading the corresponding sections in the optional Lackmann textbook may aid understanding of the course material.

Attendance 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. Other legitimate reasons for missing class include religious observance, family emergencies, and regularly scheduled university-approved curricular or extracurricular activities.  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:  This course abides by the Penn State Class Attendance Policy 42-27:, Attendance Policy E-11:, and Illness Verification Policy:

Academic Integrity Statement:

Academic integrity is fundamental not only to one’s experience at the university, but remains essential throughout one’s career.  Students are not to receive unauthorized assistance on any course quizzes or individual assessments.  Students are not to misrepresent the work of others as their own.  Serious offenses may warrant a zero on the assignment or assessment.

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:, which this course adopts.

If in doubt about how the academic integrity policy applies to a specific situation, students are encouraged to consult with the professor or TA.

Weather Delays and Campus Emergencies:

Campus emergencies, including weather delays, are announced on Penn State News (http:/ and communicated to cellphones, email, the Penn State Facebook page, and Twitter via PSUTXT (to sign up, please see  Students will not be required to attend class if campus is closed during any part of the scheduled class time.

Accommodations for students with disabilities:

Penn State welcomes students with disabilities into the University's educational programs. Every Penn State campus has an office for students with disabilities. The Office for Disability Services (ODS) Web site provides contact information for every Penn State campus: For further information, please visit the Office for Disability Services Web site:
In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation: If the documentation supports your request for reasonable accommodations, your campus’s disability services office will provide you with an accommodation letter.
