Office hours (Fall term 2005): Tues and Thurs: 3:00-4:00 pm or by appointment

 

Course Description and Objectives:

This course provides an introduction to the physical processes underlying weather and climate on time and space scales ranging upwards from the local to the global, with a particular emphasis on the formation of mid-latitude cyclones.  This course is a prerequisite to GEOG 308 (Micrometeorology) and GEOG 331 (Human Impacts on Weather and Climate).  Laboratories include use of meteorological data, maps, charts, simple instrumentation, graphical tools and numerical computation. 

 

Format:

Instruction is through two lecture hours and two laboratory hours per week.

 

Evaluation:

The material covered in lectures and labs will be evaluated in a quiz and a final exam.  Selected laboratory assignments and questions will be marked.  In accordance with university policy, missed exams cannot be made up except on written medical grounds and notification prior to exam date. 

 

Marked Laboratory Assignments           35 % 1 

Quiz                                                    15 %

Final exam                                           50 %

Notes:

1.       No late labs will be accepted after the due date.  Exceptions can be made for documented medical and other significant reasons beyond your control.  Arrangements must be made, if possible, with your teaching assistant BEFORE the due date.

 

Course Texts and Laboratory Manual:

There are many suitable textbooks for this course.  None are perfect.  None are “bad”. 

The course text for this year is:

Ackerman and Knox. 2003. Meteorology: Understanding the Atmosphere, Thomson Brooks/Cole, Pacific Grove, CA.

This is a new text to Geography 208a this year.  This book should provide a readable text for students of all backgrounds in the course.  I would like your feedback on this textbook.

Students may also continue to use earlier versions of the course text (Aguado, E. and Burt, J.E. 2004. Understanding Weather and Climate 3rd Edition; or earlier editions) or other related texts (e.g. Meteorology Today Ahrens, C.D.).  I will retain reading references to Aguado and Burt (2004) for this year; students who wish to use other texts should consult with the instructor on relevant readings. 

 

The laboratory manual contains the laboratory exercises and additional reading material.  It is required and is available for purchase from the bookstore. 

 

Course Prerequisites:

The official course prerequisite is GEOG 020E or an 020-089 level Applied Mathematics, Mathematics or Physics course.  You are responsible for ensuring that you have successfully completed all course prerequisites, and that you have not taken an antirequisite course. 

 

Prior Assumed Knowledge:

There are several areas in the course where I will assume you have some prior knowledge (covered in Geog 020E).  These topics are covered in the course text for those who need a refresher or who have not taken Geog 020E.  The topics are:

Solar Radiation and the Seasons: Chp. 2: 44-47.

Global Atmospheric Circulation:  Chp. 7 188-199.

 

Reserve Texts (Available in Weldon Library):

Danielson, E.W., J. Levin, and E. Abrams. 2003. Meteorology 2nd edition WCB/McGraw-Hill, Boston.

Stull, R.B. 2000. Meteorology for Scientists and Engineers 2nd edition. Brooks/Cole Pacific Grove CA.
