Dynamics II course 2024
Gerrit Lohmann, Monica Ionita
Summer 2024, University of Bremen
Lecture/Reading: Monday, 14-16; Prof. Dr. Gerrit Lohmann, Dr. Monica Ionita (start 14:15) Room: N3310
Tutorial: Monday, 16-17; in the same room
Hanna Knahl, Alexander Thorneloe (start 16:00)
Description
The focus of the course is to identify the underlying dynamics of the
atmosphere-ocean system. The fundamental concepts of atmosphere-ocean flow, energetics,
vorticity, and wave motion are described. These phenomena are described
using dynamical equations, climate data, as well as basic physical and
mathematical concepts. Exercises complement the lessons.
Key words
Fluid dynamics, ocean circulation, wind-driven and thermohaline circulation; atmosphere dynamics, dynamical system theory, non-dimensional parameters, bifurcations and instabilities; Gravity, Rossby, and Kelvin waves; Conceptual models, Analytical and Programming techniques; Time series analysis
Learning outcome
Advanced dynamics of the ocean and atmosphere, applications in the fields of climate dynamics and fluid mechanics. Programming skills and usage of the climate data operators. Theoretical concepts in physics of climate, temporal and spatial scales of climate dynamics.

Course and examination performance
There are two parts: Course achievements and examination achievements (Studienleistungen und Prüfungsleistungen)
Course achievements:
50% of the points of the exercise sheets are required. Furthermore, we require active participation with at least one time showing a solution.
Working in study groups is encouraged, but each student is responsible for his/her own solution. If the solution is typewritten (e.g. with LaTex, Rmarkdown, or word), we allow up to 3 persons to be listed on a solution sheet. Send in your solutions in form of a PDF to our email addresses (one PDF per group!).
Examination achievements:
You have to pass the written exam xxx Room yyy
The exam is based on the exercises and the general content of the lecture. The procedure follows the rules of pep.
