GEF4510 - Atmosphere and Oceans on Computers: Fundamentals
Course content
Governing equations, hyperbolic, elliptic and parabolic systems, finite difference methods, truncation errors, orthogonal functions, numerical stability, explicit and implicit methods, elliptic solvers, numerical dispersion, diffusion and dissipation, unphysical modes, solutions to diffusion and advection problems and their combinations, solutions to the shallow water equations, higher order schemes, generalized vertical coordinates, open boundary conditions.
Learning outcome
You will gain an appreciation of and a knowledge about the fundamental numerical methods used to solve atmospheric and oceanographic problems. These methods are at the core in numerical weather prediction models and the similar numerical prediction models used to predict ocean variables. You will also learn about parameterization of som key processes in the atmosphere and ocean, in particular about the so called subgrid scale (SGS) parameterizations.
Admission
Students at UiO must apply for courses in StudentWeb.
International applicants, if you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.
The examination in this course is not available for external candidates. Only students admitted to the course may sit for the examination.
Overlapping courses
7 credits overlap with GEF4230 - Numerical models of the atmosphere (discontinued) and 7 credits overlap with GEF4620 - Numerical solutions of oceanographic problems (discontinued).Teaching
2 times 2 hours per week throughout the fall semester. Lectures and evaluation of compulsory exercises. The compulsory exercises must be approved (no letter grades) before the student may take the final exam
Examination
Oral, final exam (counts 100%).
Grading scale
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.
External auditor: Inger Hanssen-Bauer
Explanations and appeals
You may request an explanation of your grades, and you may also appeal against your grades or make a complaint about formal examination errors. Read more about explanations and appeals.
Resit an examination
You can usually resit an exam, but the conditions depend on whether you had a valid reason for absence from the regular exam. Read more about resitting an exam.
Withdrawal from an examination
A student may sit this exam up to 3 times. If a student wishes to withdraw from the exam, s/he must do so in StudentWeb at least two weeks prior to the first day of the exam. Failure to do so will be counted as one of the three opportunities to sit the exam.
Special examination arrangements
If you have a disability or a health problem that entails significant inconvenience in an examination situation, you may be considered for special examination arrangements. Mothers who are breastfeeding may apply for extra time to complete the exam.
