This module is designed to give a general introduction to meteorology and its relation to climate and climate change, concentrating on the physical processes in the atmosphere and how these influence our weather. The course contains both descriptions and mathematical treatments of meteorological topics and the assessment is designed to allow those with either mathematical or descriptive abilities to do well; however, a reasonable mathematical competence is essential, especially in rearranging equations, and a familiarity with basic calculus is helpful. Co-taught with ENV-2A23. TO TAKE THIS MODULE YOU CANNOT HAVE PREVIOUSLY TAKEN ENV-2A23 OR EQUIVALENT
