Objectives and Content

Objectives:

The course provides the fundamentals of the atmosphere and ocean dynamics, and thus sets an important part for understanding climate dynamics. The starting point is conservation of mass and momentum and the equations that can be derived thereof, expressed in both non-rotating and rotating coordinate systems. Physical interpretations of the equations are presented and simplified expressions are used to explain, understand and compute large-scale and free movements in the atmosphere and the oceans.

Content:

Derivation of the primitive equations from first principles in a non-rotating and a rotating coordinate system. Derivation and discussion of simplified balance equations (geostrophy, thermal wind, effect of friction, etc.) that are commonly used to describe and analyse large-scale movements in the atmosphere and the oceans. Review and discussions of the basic momentum and energy budgets of the atmosphere. Equation-based analysis of the ocean circulation caused by thermohaline and surface wind forcings. Review of the Ekman and Sverdrup dynamics. Review of fundamental waves in the atmosphere and oceans, including analysis of Kelvin and Rossby waves.

Learning Outcomes

On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student

Access to the Course

Access to the course requires admission to a programme of study at The Faculty of Mathematics and Natural Sciences

Teaching and learning methods

The teaching is given as lectures and exercises

Lectures 4 hours each week/13 weeks

Exercises 2 hours each week/ 12 weeks

Forms of Assessment

Midway exam, written, 2 hours: counts 20% on the final grade and is valid for two semesters (the semester is has been attended and the following semester.) Final exam, written, 4 hours: counts 80% on the final grade and must be passed. It is mandatory to have attended the midway exam in order to take the final exam. If less than 10 candidates, the exam might be oral. Information regarding the form of the exam will be given early in the semester.

Examination Support Material

Non-programmable calculator, according to the faculty regulation

Grading Scale

The grading scale used is A to F. Grade A is the highest passing grade in the grading scale, grade F is a fail.

Assessment Semester

Examination both spring semester and autumn semester. In semesters without teaching the examination will be arranged at the beginning of the semester.

Reading List

The reading list will be available within June 1st for the autumn semester and January 1st for the spring semester

Course Evaluation

The course will be evaluated by the students in accordance with the quality assurance system at UiB and the department.

Programme Committee

The Programme Committee is responsible for the content, structure and quality of the study programme and courses.
