METO451 - Atmospheric and Oceanic modelling
Prerequisites: Math 246 or equivalent.  The processes that regulate the earth's climate are too complicated to be represented in a laboratory.  Instead, the physical and chamical principles can be used to construct computer models of the natural system, which then serves as a base from which to conduct experiments.  In this course we introduce the student to key physical and chemical processes in the atmosphere and ocean and use these to address the important problem of short term climate variability.
