GEO4900 – Atmosphere-Ocean Dynamics
Changes in the course due to coronavirus
Autumn 2020 we plan for teaching and examinations to be conducted as described in the course description and on semester pages. However, changes may occur due to the corona situation. You will receive notifications about any changes at the semester page and/or in Canvas.
Spring 2020: Teaching and examinations was digitilized. See changes and common guidelines for exams at the MN faculty spring 2020.
The course deals with the fluid dynamics of large scale motion on Earth, with application to the atmosphere and ocean. Motion at such scales, including storms, the Jet Stream and Gulf Stream, is profoundly influenced by the Earth´s rotation. Key aspects of the motion can be captured with simplified dynamics, as shown in the course.
The student will obtain a fundamental knowledge of:
- the equations of motion for a rotating system
- the geostrophic and hydrostatic balances, and the thermal wind relation
- gravity and planetary waves
- turbulent boundary layers and the energy cascade
- barotropic and baroclinic instability
- simplified models of the atmospheric and oceanic circulation
Admission to the course
Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.
Nordic citizens and applicants residing in the Nordic countries may apply to take this course as a single course student.
If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.
Recommended previous knowledge
- 10 credits overlap with GEO3900 – Atmosphere Ocean Dynamics (discontinued).
- 10 credits overlap with GEF3450 – Geophysical Fluid Dynamics (continued).
- 10 credits overlap with GEF4450 – Geophysical Fluid Dynamics (continued).
2 x 2 hours of lectures and up to 2 hours exercises per week. 6 obligatory problem sets, which must be passed prior to the final exam.
Attendance at the first lecture is compulsory. Students who fail to meet, are considered to have withdrawn from the course unless they have previously given notice to the Student administration (email@example.com).
We reserve the right to change the teaching form and examination of the course in semesters where 5 or fewer students have been admitted.
- Six written submissions which count for 40% of the final grade, and which have to be passed before you can take the final exam.
- Final written examination (3 hours) counts for 60%.
- Both the written submission and the final written examination must be passed individually in order to pass the course.
It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.
It will also be counted as one of the three attempts to sit the exam for this course if you sit the exam for one of the following courses:
- GEF3450 – Geophysical Fluid Dynamics (continued)
- GEF4450 – Geophysical Fluid Dynamics (continued)
- GEO3900 – Atmosphere Ocean Dynamics (discontinued)
Examination support material
- Approved calculator and Rottmann´s mathematical formula collection.
Language of examination
The examination text is given in English. You may submit your response in Norwegian, Swedish, Danish or English.
Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.
Resit an examination
Students who can document a valid reason for absence from the regular examination are offered a postponed examination at the beginning of the next semester.
Re-scheduled examinations are not offered to students who withdraw during, or did not pass the original examination.
