This course is an introductory physical geography course that investigates processes in the atmosphere that determines climate and weather. There are three broad areas of study: 1) processes in the atmosphere, which determine temperature, precipitation, etc.; 2) atmosphere in motion, which determines the actual weather; and 3) environmental challenges such as air pollution and climate change. First we examine the structure of our planet’s atmosphere, and then we add movement to the system before we delve into topics of global concern such as air pollution and climate change.
