Course Description
Extreme weather eventsareinvestigated with much attention again to the larger scale atmosphericsystems (e.g. wave cyclones, squall lines, supercell thunderstorms) that support their development and sustenance. Theingredients and recipes responsible for their production of extreme weather eventsare explored. The ingredients refer to the suite of physical conditions that are brought togetherin space-time by the systemto produce the extreme weather. The recipes, in turn, describe the different ways in which the ingredients can be brought together in space and time to spawn the extreme weather.
- In the first two quarters of the course, the processes and atmospheric patterns that produce extreme weather are described along with the conceptual model of weather entities as living systems. These are applied to weather entities that produce extreme cold air outbreaks, ice storms, snowstorms and high winds. The processes and patterns in the cool seasonextra-tropicalatmosphere are described first, followed by an examination of the cyclonic and anti-cyclonic systems that bring together the ingredients for extreme weather.
- In the third quarter of the course, severe thunderstorms, very heavy rainfall, and tornadoes are examined with a focus on the supporting meso-scale patterns and processes. Particular attention is given to meso-scale convective systems and how larger scale cyclonic systems assemble the ingredients to produce and maintain these entities.
- In the last quarter of the course, heat waves and drought are examined and tied to larger scale,persistent anticyclonic systems that support their development. Tropical cyclonic systems (i.e. hurricanes) areinvestigated as well with a focus on the factors that control their strength and movement.
- Climatologies of each event type aredescribed, specifically when and how frequently they occur. Also, changes in the frequencies of these extreme events are related toglobal climate change.
- The first 5 to 10 minutes of class are used to describe what is going on with the weather both locally and nationally. A wide variety of web-based weather products (e.g. weather observations & maps, satellite imagery) are described and used to provide a spatial perspective on how the ingredients come together to produce extreme weather.
This wide breath of material in this course is treated in a largely conceptual manner with a minimal amount of time devoted to the underlying mathematics. A diagrammatical-spatial approach will be used in lecture whereby processes and their interactions in the atmosphere will be described using numerous maps and conceptual diagrams. Because of the breath and complexity of the lecture material you will need to spend time outside class learning the nomenclature, coming to grips with concepts, and linking these concepts together to build conceptual models of the atmosphere. Although attendance will not be taken, you are expected to show up for class prepared to discuss to the lecture material. Finally you are expected to observe the weather during the semester and participate in discussions.
Weather Quizzes
A weather quiz will be posted on Sakai most Wednesdays of the week (beginning on 1/23). The quiz will consist of 20- 30 questions that address key concepts and weather patterns revealed from various maps and charts. This is an open book quiz that you will be able to take two times. You will receive online feedback re: the questions you missed upon completing it the first time. The quiz must be taken between Wednesday and midnight on the following Sunday.
Weather Notebook.
Details will be provided.
Course Materials
Lectures will be the primary source of material for the course. Lecture outlines with maps & figures (PDF and Power Point format) will be made available in the Resources folder in Sakai. Please note that these are merely outlines; you will need to come to class and write the lecture notes.
There is no required text for this course; however, web links to supplementarylecture material will be provided. In addition various material will be made available on Sakai.
While the background material for this course is largely provided in geog 110 and 111, it will be helpful to reference an introductory level textbook regarding basic atmospheric concepts and first principles. Power Point lecture outlines will be provided on Sakai.

Attendance Policy: Students are expected to attend all class meetings and participate in all activities in lecture and studio meetings. Excused absences can be granted only by the lead instructor or the studio coordinator, one of whom must be informed in advance of the date of the absence except in cases of sudden illness or other emergency.
Honor Code Policy: The Honor code and the Campus Code, embodying the ideals of academic honesty, integrity and responsible citizenship, have for over 100 years governed the performance of all academic work and student conduct at the University. Acceptance by a student of enrollment in the University presupposes a commitment to the principles embodied in these codes and a respect for this significant University tradition. Your participation in this course is with the expectation that your work will be completed in full observance of the Honor Code.
Academic dishonesty in any form is unacceptable, because any breach in academic integrity, however small, strikes destructively at the University's life and work. If you have any questions about the Honor Code, please consult with someone in the Office of the Student Attorney General or the Office of the Dean of Students.
Students are expected to abide by the Honor Code in all classroom activities. Collaboration is explicitly allowed on assignments that are designated as group submissions. Discussion with other students prior to submitting an individual answer is also permitted on personal response activities in lecture and on homework exercises, as described above. All other graded assignments (warm-ups, individual studio assignments, quizzes and exams) must be submitted without any aid not explicitly authorized by the instructors.
