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.
On completion of the course the student should have the following learning outcomes defined in terms of knowledge, skills and general competence:
- understands how the movements in air and water are formed on a rotating planet with warming at low latitudes and cooling at high latitudes
- has broad knowledge about how to formulate the equations that describe the large-scale wind and current systems
- has knowledge about the historical development of the field that dealing with the dynamics of the atmosphere and the oceans
- is able to derive the fundamental equations describing the large-scale movements in the atmosphere and the ocean
- is able to compute the movements in the atmosphere and ocean based on various choices of coordinate systems
- is able to derive, apply and interpret the equations for geostrophic flow and the thermal wind, and can use variations of these to large-scale and synoptic systems in the atmosphere and the oceans
- is able to read up on advanced studies of atmosphere, ocean and climate dynamics
- is able to calculate and interpreted the basic effects of friction on the atmosphere and ocean dynamics
- is able to apply fundamental physical principles to explain the large-scale, atmospheric and oceanic circulation
- is able to derive and apply basic expressions of the Ekman and Sverdrup dynamics in the ocean
- can explain mathematical concepts and apply mathematical formalism on a series of geophysical problems
- can convey and discuss the physical basis for the understanding of large-scale movements in the atmosphere and the ocean
- is familiar with and can utilise an extensive set of formulas used to analyse and interpret movements in the atmosphere and the ocean
- can reflect on central, ethical and scientific issues in the field

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.
Due to the measures taken to avoid the spread of SARS-CoV-2, UiB has recuedcapacity for physical teaching and assessment. As a consequence, the following changes is made to assessment spring semester 2021:
- Written home examination instead of written examination, the duration of the exams will be as described above.
Examination Support Material
Non-programmable calculator, according to the faculty regulation
The grading scale used is A to F. Grade A is the highest passing grade in the grading scale, grade F is a fail.
Examination both spring semester and autumn semester. In semesters without teaching the examination will be arranged at the beginning of the semester.
The reading list will be available within June 1st for the autumn semester and January 1st for the spring semester
The course will be evaluated by the students in accordance with the quality assurance system at UiB and the department.
The Programme Committee is responsible for the content, structure and quality of the study programme and courses.
