9. Course learning outcomes
In this course you get an observationally based view on the large-scale behavior of the Earth’s atmosphere and learn how this behavior can be understood theoretically using thermodynamic and hydrodynamic principles. In particular, you gain a detailed understanding of the atmospheric energy and angular momentum budgets and the role of different atmospheric circulation systems in transporting energy and angular momentum.
10. Course completion methods
The course has weekly lectures and exercises. Attendance is not obligatory but recommended.
To complete the course, you need to get a sufficient total number of points from the exams and exercises.
Thermodynamic and hydrodynamic laws governing the behavior of the atmosphere and their basic applications (e.g. from the BSc level courses FYS2032 Atmospheric thermodynamics and FYS2033 Introduction to Atmospheric flow dynamics). Overview of the heat budget of the surface and the atmosphere (e.g. from FYS2035 Physical Climatology). Derivation and integration. Common vector operations. Fourier series.
12. Recommended optional studies
Participation to the courses ATM348 and ATM349 (Dynamics of atmospheric flow structures I-II) before this course is recommended.
13. Course content
Observed time mean conditions and variability in the free atmosphere
Temporal filtering of time series
General balance conditions for time mean variables in the atmosphere
Zonal angular momentum budget in the atmosphere
Different forms of energy in atmosphere
Budget of atmospheric dry and moist heat and potential energy
Budget of kinetic energy and available potential energy
Theory of the formation of the zonally averaged time mean flow, including in particular the interaction between the mean flow and eddies and the maintenance of the Ferrel cells.
Stationary waves in the atmosphere and their maintenance mechanisms. Propagation of stationary Rossby waves.
Low-frequency atmospheric variability and its causes, with a focus on the ENSO (including its teleconnections) and NAO phenomena.,
Numerical simulation of climate with coupled atmosphere-ocean climate models, the main feedback mechanisms and the parameterization problem.
14. Recommended and required literature
Lecture compendium "Ilmakehän yleinen kiertoliike I"
15. Activities and teaching methods in support of learning
Weekly lectures and exercises. Individual work. Total hours 135.
16. Assessment practices and criteria, grading scale
Grading is based on the exam (75%) and exercises (25%). 45% of total maximum points is required for grade 1/5. 85% of total maximum points is required for grade 5/5.
