MET 2010: INTRODUCTORY METEOROLOGY
Meteorology is the scientific study of the structure of the atmosphere and the processes
involved in creating weather. Weather's effects on the earth have always been a major
determining factor in the distribution and survival of land-based species. Humans uniquely
have developed the ability to understand and manipulate atmospheric processes. Our
increasing knowledge of the atmosphere and our expanding technology that can affect it
must be accompanied by a responsibility as to its maintenance. A more thorough
understanding of the delicate balance between our activities and the dynamics of the
atmosphere will hopefully encourage a greater respect for this most vital (and fascinating!) of
natural environments.
Major Objectives:
1. To develop an understanding of the meteorological environment and the physical laws
governing it.
2. To develop an awareness of how the interactions between solar energy, air, land, and
water form weather.
3. To apply knowledge of the physical laws that control weather with data of current
weather conditions to forecast future weather.
4. To better understand how humankind’s activities can affect the quality of the
atmosphere.
Grading policy: The course will be organized into four units, outlined in the attached
objectives. An exam will be administered upon completion of each unit; dates will be
announced at least one week in advance. Exams will be composed of short answer and fillin-the-blank type questions. All exam material will be covered in lecture. Each exam will
count for 20% of the final grade. An end-of-the-semester forecasting exercise will count for
15% of the final grade. The remaining 5% will come from periodic exercises, which are
designed to help prepare you for the exams.
You are expected to be present for every exam! If you miss an exam, essay make-ups will be
available for one week after the original exam. No make-up is available for the final exam.
If, for reasons of scholarship eligibility, academic probation, or simple pride, you feel you
must earn a specific grade during the semester and are not reaching that level, options are
available. A maximum of 20 extra credit points (to be added on to the lowest test score) can
be earned through a combination of the following: presenting the daily forecast to the class,
attending AMS meetings, submitting short papers on assigned weather questions or
reviewing television/online weather specials. The weather questions will be given at the end
of class and posed in the form of more detailed questions concerning material just covered in
class. Acceptable TV/online specials will be posted on your class calendar and your review
should describe the contents of the show in some detail and end with a brief paragraph
expressing your opinion of the show you viewed. Both the questions and the summary
should run at between 500-750 words and can be submitted to me online.
To rescue oneself from a truly abysmal test grade, two options may be considered:
1) Anyone who fails an exam may take the essay exam. Your two scores on the exam will
then be averaged for a final score. No retakes will be available for the final exam.
2) You may write a 1200-1500 word term paper to replace ONE test score. (A paper cannot
be written in place of taking the test.) I must approve the subject in advance. The paper
must follow basic term paper style and include three to five sources, excluding encyclopedias
(online and hard copy) and textbooks.
The grade on this paper will automatically replace the test score. The paper is due the class
period before the final exam. No term papers can be substituted for the final exam.
All work for the course must be in by the day of the final exam - no exceptions!
Final grades for the semester will be calculated as follows:
A
B
C
D
F
90-100
80-89.5
70-79.5
60-69.5
Below 60
Attendance policy: The college-wide attendance policy is included in the Syllabus
Addendum http://www.spcollege.edu/addendum . The policy notes that each instructor is
to exercise professional judgment and define “active participation” in class (and therefore
“attendance”), and publish that definition in each syllabus. For this class, attendance is
defined as: each student is expected to be present and on time for every class, and to stay for
the entire class period. Attendance is taken during every class. Regular attendance is vital
for anyone wishing to pass the course and is used as a determining factor in borderline grade
cases. In the event an unforeseen situation occurs in which you will miss several classes,
contact me as soon as possible to arrange to make up any missed work. You are responsible
for all missed class material.
Withdrawal: Any student who is a “no show” for the first two weeks will be automatically
withdrawn. The official withdrawal date is March 23. If you wish to withdraw, it is your
responsibility to do so by this date. The college assigns a “WF” to any student withdrawing
after that date. Students who are not actively participating in class (more than three
absences) will be reported to the Administration during the week following the last date to
withdraw with a “W”. Any student failing to show up for the final exam will be assigned an
“F”. Particularly if you are receiving financial aid, you need to know the consequences of
withdrawal: http://www.spcollege.edu/withdrawal/
Classroom policy: All mobile devices must be turned off while in class. Use of any
device or texting during class is a violation of college policy and subject to disciplinary
action. In addition, college policy mandates that absolutely no food or drink (other
than bottled water) be brought into the classroom.
Academic Honesty/Classroom Behavior: http://www.spcollege.edu/academichonesty/
Students receiving Veteran Benefits: SPC rules require that administration be notified at
any point during the semester if a student receiving veteran benefits is absent for two
consecutive class periods. Please refer to:
http://www.spcollege.edu/pages/veterans.aspx?id=1649
Students with Disabilities: If you need special accommodations as a student with a
documented disability, please contact Jeff Ziegler, the campus Learning Specialist, at 7912710, particularly if you need assistance during a possible emergency evacuation. Please
see: http://www.spcollege.edu/dr/
Recommended Textbook: The Atmosphere (13th edition) by Frederick Lutgens and Edward
Tarbuck. You can get an online copy for considerably less than a hard copy at this website:
www.mypearsonstore.com/bookstore. Enter the last names of the authors (upper right) and
then select this text – you’ll have several digital options on the right, including eTextbook.
Instructor: Ms. N. Duncan Tabb. We will be meeting every Tuesday and Thursday from
12:30-1:45 in NM 226, Clearwater Campus. You can reach me in my office, NM 106, two
hours after class each day. If I am not in my office during those hours, check NM 226. If
you want or need to reach me at any other time, you can either call or text me at 492-8708,
or e-mail me through our D2L site or at duncantabb.neva@spcollege.edu. You can also leave
me a message with our science department: 791-5955. You can access my webpage at:
