E-Mail:

    All students in 101 need to provide an email address for important messages.  Email will serve as an important conduit of information between the instructor and students.  It is expect that students will check their emails regularly (at least once a week).  To get on the class email list, use your browser to go to

and fill in the required information (name and email).  Make "subscribe" is darkened and then hit "next"

Textbook: Essentials of Meteorology: An Invitation to the Atmosphere, by C. Donald Ahrens, 2001 , 3rd Edition. (a copy is on 6-h reserve at the undergraduate library)

Homework:

There will be five homework assignments--the lowest grade will be dropped. Homework will be handed out Wednesday and is due Tuesday of the next week at the beginning of class. No late homework will be accepted.

Enhancement Sections:

    For those students who want to learn more, we will be having some extra sessions during the quarter.  Times will vary to fit with varying schedules.  One session will include a visit to the department map room and to view the sensors on the atmospheric sciences roof.  Others will give more background on the forecasting process, weather radar, and weather satellites.

Exam Schedule

First Mid-Term Exam:  25 January (this day may change)
Second Mid-Term Exam: 22 February (this day may change)
Final Exam:  12 March, 8:30 AM-10:20 AM

Grading:

2 midterms, 50%; Homework/Labs, 20%; Final exam, 30%. Extra credit available for those in the forecast competition (maximum of 15 points additional points on the final, depending on your performance).
