Description

Master’s Programme in Atmospheric Sciences is responsible for the course.

Module where the course belongs to:

  • ATM300 Advanced Studies in Atmospheric Sciences
    Compulsory for:
    1. Study Track in Meteorology

The course is available to students from other degree programmes.

This course is direct continuation to ATM348 Dynamics of Atmospheric Flow Structures I.

A more detailed treatment of tropical dynamics is given in ATM356 Convective weather systems and climate.

The course gives you a theoretical understanding of baroclinic instability and an overview of the dynamics of the tropical atmosphere.

First year of MSc studies, after ATM348 Dynamics of Atmospheric Flow Structures I. Each year in period II.

  • Concept of hydrodynamic instability and methods for assessing the instability of an atmospheric flow situation
  • Conditions for baroclinic instability, as inferred from the quasi-geostrophic two-layer model
  • Energy cycle of baroclinic waves
  • Barotropic instability
  • Consequences of non-linear processes on the energy spectrum of atmospheric waves (Fjørtoft's theorem)
  • Basic characteristics of the tropical atmosphere and the differences from higher latitudes, as inferred from observations and scale analysis.
  • The most important flow structures and circulation systems in the tropical atmosphere.

Lecture notes

  • J. R. Holton & G. Hakim, 2012: An Introduction to Dynamic Meteorology, 5th edition. Chapters 7 and 11.
  • Lecture Compendium "Dynamics of Atmospheric Flow Structures: Supplement to the Text Book of Holton and Hakim (2012)"

Weekly lectures and exercises (individual work). Total hours 135.

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.

The course includes 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.
