Aim of the course: To provide a rigorous introduction into the processes that are crucial in shaping climate; to introduce students to the art and science of constructing simplified models that help to obtain conceptual understanding

Concepts and models are introduced that help us to understand fundamental aspects of the Earth’s climate, such as global mean temperature, global-scale temperature differences, and what might cause these to vary on timescales of decades and longer. Particular emphasis will be placed on oceanic and coupled ocean-atmosphere processes. While we cover observed elements of the climate system and a hierarchy of models ranging from the simplest ones to general circulation models, the focus will be on conceptual understanding throughout. Discussing what is not understood, and hence identifying areas of current and future research, will be a crucial element.

Method of assessment: 50% homework assignments, 50% course project report.
