ATMO 441a/551a Syllabus

Topics and their presentation order are subject to reasonable change. There is insufficient time to cover every topic, so some will be skipped or treated lightly. What appears in red is the plan. Material from Holton chapters 1-4 will be covered initially. An overview of chapter 5 and most of chapters 6 and 7 will likely follow.  Tidbits from chapters 8 and 12 could follow, time permitting. Any other material is highly unlikely.
