ATMO 170A1:  Introduction to Weather & Climate

Fall 2017 - Online
Sections 104 & 105

Course Description

An introduction to the science of weather and climate. Topics are selected from atmospheric composition, energy balance, wind systems, genesis of fronts and cyclones, precipitation processes, clouds, severe weather, weather and climate forecasting, climate and optical phenomena. Emphasis is placed on the illustrating the fundamental importance of physics, chemistry, mathematics and biological processes to the atmospheric sciences. The first part of the course concentrates on fundamental concepts (e.g. energy conservation, heat transfer, phase changes of water, force and momentum) that are needed to understand the structure and behavior of the atmosphere. The second half deals with specific meteorological phenomena. Emphasis is given to phenomena that have strong impacts on human welfare and economic livelihood such as winter storms, heat waves, drought, floods, severe thunderstorms, hurricanes, air-sea interactions (El Nino/La Nina events), climate change (natural and anthropogenic), ozone depletion and regional air pollution.

Learning Goals and Student Outcomes

By the end of this course, you should:
1)    Understand how the warming of the earth by the sun and energy transfer through the atmosphere drive weather and climate change.
2)    Appreciate the impact that weather and climate has on life, and that life has on the atmosphere.
3)    Be in a position to evaluate the soundness of ''weather/climate science'' that appears in the mainstream media and to make informed decisions on what to do about projected anthropogenic changes in extreme weather events and climate.

Textbooks:


Required Textbook
C. Donald Ahrens and Robert Hanson
Essentials of Meteorology: An Invitation to the Atmosphere, 8th Ed.
An eBook version of the textbook is automatically included as part of the course at an additional cost of $80.00. The cost includes access to the eBook though the semester. You will be charged $80.00 by the Bursar's Office unless you cancel the subscription before the end of the online add/drop period. Access to eBook is via D2L. The Inclusive Access Program with D2L access is the cheapest available eBook version of the text.

If you would rather have a hard copy of the textbook instead of an eBook, the ISBN is 978-1-305-62845-8 for the bound book and 978-337-27610-8 for the loose-leaf version. Hard copies are available special order from the ASUA Bookstore or from several online vendors. I do not know the prices, but their costs are greater than $80.00 price of the Inclusive Access Program and do not include access to some animations and videos that the eBook includes. If you purchase a physical copy of the book, be certain to cancel the Inclusive Access Program within the first two weeks of the term to avoid being billed.

Although I do not recommend using an earlier edition of the textbook, I can report that some students in prior sections used cheaper copies of the 7th edition (and even the 6th edition) and successfully passed the course. If you decide to use an earlier edition of the textbook, you are 100% responsible for aligning similar subject matter in an older edition so that matches the material in the reading assignments that are posted below.

There may be mandatory readings from sources other than the textbook. They would be announced and posted on D2L.

Other Course Materials:

Syllabus and email policy (both mandatory readings), auxiliary readings, homework assignments and term project, and online exams are only accessible on D2L.

Class List Serve:

Use the class list serve for issues and questions of general interest to the entire class.
