Earth and Climate physics

Course content

The purpose of the course is to provide an overview of the Earth and its climate system and the underlying physical processes, and to develop simple numerical models of phenomena related to the Earth and its climate.

The course provides a basic understanding of the various components of the Earth’s climate system and their interactions. The course introduces the fundamental physics principles and observations needed to understand the present and past climate, and the basic processes that shape the Earth and influence climate evolution on a planetary scale. The physics principles involve thermodynamics, radiation physics, heat transfer, celestial mechanics, fluid mechanics, and various other processes. Simple numerical models are developed as an integrated part of the course to investigate Earth system phenomena. The numerical modelling will involve solving simple partial differential equations.

Themes:

  • The surface energy balance and heat transport
  • Large scale ocean circulation
  • Glacial cycles and ice sheet dynamics
  • Orbital parameters and variation of temperature with season and latitude
  • Atmospheric composition and evolution of climate
  • Interactions between the major elements in the climate system: the atmosphere, the ocean, the ice sheets, the solid earth and the biogeochemical system.

The course contains lectures, exercises and computer exercises where students work with simple models. The students form groups of 2-3 students and choose an exam modelling project (which will contribute with 50% to the evaluation). The groups will work on their projects during the remaining exercises of the course. We recommend that the programming language MATLAB be used for the modelling.

Skills
After completing this course, the student will be able to:

  • Understand the role of the atmosphere, the ocean the ice sheets and the solid Earth in the climate system.
  • Describe the climate evolution of the Earth (snowball Earth, greenhouse Earth, glacial cycle, global warming) and the key physical processes.
  • Use simple numerical models to describe the interaction between the atmosphere, the ocean, the ice sheets and the solid Earth.
  • Develop a numerical model in Matlab (or an equivalent language).
  • Present and discuss the results of the numerical model in a written report.
  •  

Knowledge
During the course, simple models of the Earth's climate system will be presented. Emphasis will be placed upon physical interactions and feedbacks between the atmosphere, the oceans, and the ice sheet components of this system. Some subjects that will be covered will be energy balance and heat transport, large scale ocean circulation, glacial cycles and ice sheet dynamics, orbital parameters and variations of temperature with season and latitude.

Competences
Through this course, the students will see how the fundamental physics principles governing the components of the Earth and its climate system result in complex behavior when interacting on a planetary scale. They will further see how simple numerical models can be used to obtain understanding about a complex topic such as the Earth’s climate. The student will be competent in using and extrapolation knowledge from these models. Development of numerical models has applications in a wide range of fields within physics.
