Climate System as a Part of Environment
The physical science of the climate system, which consists of the atmosphere and the hydrosphere, is presented. Based on such physical laws as conservation of mass and of energy, an overview of the energy and water cycles in the climate system is shown, with emphasis on the atmosphere. Climate change, in particular, global warming due to increase of carbon dioxide in the atmosphere, is discussed from the viewpoint of changes in energy and water cycles.
The students will understand and the principal physical variables concerning the stocks and flows of energy and water in the climate system, as well as the mutual relationships, and will manipulate numerical variables representing them. They will be able to calculate rough numerical values concerning possible changes in the energy and water cycles of the climate system when forcing is given.
Fifteen lectures will be given, once a week. Short assignments will be given, roughly once in 3 lectures, to calculate some physical quantities related to mass and energy. The lectures will cover following subjects. The relationship between subjects and lectures is not straightforward and difficult to fix beforehand, but will be shown in the web pages linked from the page indicated in the "Related URL" section of this syllabus, and will be frequently updated.
No formal course achievements are required. Knowledge of physics, chemistry and mathematics which are covered by first-year mandatory classes of the School of Agriculture may be presumed. The assignment of calculation in the end-of-term report may presume some capability to use computers comparable to the first-year classes of information processing. (The short assignments will be easy enough so that hand calculation may suffice.) The instructor will explain procedures of calculation, but will not teach how to use computers.
No textbooks will be specified. The course materials, including introduction to reference publications, will be posted on a page linked from the "Related URL".
More will be introduced on a web page linked from the "Reference URL".
Small assignments, 4 times (evaluation focus: responding in-time), 10 points each. End-of-term report (Explanation of some concept and calculation of some quantity. Evaluation focus: understanding of course materials and ability to handle numerical quantities), 60 points.
We should recognize nature in diverse qualities. We should also recognize nature in physical quantities. Both are important, and I expect you to develop both abilities.
