Lab manual:                  Your Instructor will provide you with lab exercises each week.

 

Course Description:

 

This course is designed to provide students with an understanding of the dynamic processes at play within the Earth’s fluid atmosphere and an appreciation of the role of these processes in producing weather. Topics covered on the course include: the origin and evolution of the Earth’s atmosphere, the structure and characteristics of the atmosphere, the Earth/Sun relationships and their influence on the seasons, solar and terrestrial radiation, the hydrologic cycle, the gas laws, global circulation, weather systems and fronts, storms and analysis of weather maps. Weekly laboratory exercises have been designed to complement the topics covered in lecture.

 

Grading:

 

Students’ grades for this course will be determined at the end of the semester based on the results of quizzes taken during the term, a final exam, and an evaluation of each student’s daily class and laboratory work completed during the semester. Quizzes will be given weekly during the semester and their average at the end of the semester will constitute 50% of the grade for the course  The final exam counts 30% and the student’s labs and daily work counts 20%. The daily work and labs of students will be evaluated on the basis of accuracy, completeness, neatness and timeliness in completing the assignments.  Note: there are no make-ups for any tests that you miss during the term. Your score on the final exam will replace that of any test you have missed. The final exam is cumulative.

 

A letter grade will be given to each student at the end of the semester based on their numerical average as follows:

           

100 - 93 = A

86 - 83 = B

76 - 73 = C

66 - 63 = D

  92 - 90 = A-

82 - 80 = B-

72 - 70 = C-

62 - 60 = D-

  89 - 87 = B+

79 - 77 = C+

69 - 67 = D

59 or less = F

 

Attendance:

 

Attendance at lectures and laboratory exercises is essential if students are to be successful in this course. The college policy is to allow students a number of cuts from class, without suffering an academic penalty,  which is equal to the number of credits for that course. This works out to be equal to the equivalent of one week of class. If your absences from class (for whatever reason) exceed this number, which in this case is 4, you are in serious danger of not being able to successfully complete the course.

Absence from class does not absolve one from responsibility for the material covered in class or  assignments given while they were absent.

 

Teaching Procedures:

 

Classes are conducted in an informal lecture/discussion format in which students are expected to actively participate. The instructor will ask for questions and answers during the discussions and students should be prepared to participate. Frequent use of audio/visual materials is made to help enhance student understanding of the scientific concepts covered in class. In addition, there is a weekly laboratory exercise.

 

Using Your Text Effectively:

 

Learning meteorology, like acquiring any knew knowledge or skill, requires work. In my on-going, personal process of continuing education, I’ve found the following steps to be very effective in the educational process.  Most importantly, be realistic, while some concepts can be understood easily and almost immediately, understanding other concepts may come more slowly and require a great deal more effort on your part. All of us will have this experience so be patient with yourself. The important thing is to set aside time each day for study and/or review in all your subjects.

 

In reading any assignment, begin by reading the introductory paragraph and by looking at the pictures in order to get a general sense of the subject matter. Turn the pages of the chapter and familiarize yourself with what the objects you will be reading about look like. Pictures can be worth a thousand words. Next, turn to the summary at the end of the chapter. Finally, start again and read the assigned material. Depending on the length of the assignment, you may not be able to complete this task in one sitting. If not, read the assignment by section so that you don’t end in the middle of a topic. This way, when you are refreshed, you can come back to the assignment at a logical beginning point. As you read, make notes of things you don’t understand. You should ask your instructor for help in understanding these questions. I would urge you not to rely on highlighting as you read. It will be much more effective for you to get into the habit of writing down short notes and constructing a simple outline of what you have read.

 

Look carefully at the pictures and diagrams. If the caption of a figure poses a question, try to answer it. Make your own diagrams, without referring to the one in the text, to be sure you understand what they represent.

 

As you encounter words or terms in the text that you aren’t familiar with, look them up in the index or glossary at the back of the book. It is a waste of your time to be reading a description of an object or concept without having an understanding of the terms used in describing it. You should seek help from your professor and/or assistants in the academic resource center whenever that assistance is needed. Don’t be shy about asking questions. This is how we get to an understanding of new ideas.

 

 

Students with Disabilities:

 

Students with disabilities who believe that they may need accommodations in the classroom are encouraged to contact the Learning Disability Coordinator, Nancy Sullivan at extension 1082, or Disability Councilor, Stan Oliver at extension 1464, as soon as possible, in order to ensure that such accomodations are implemented in a timely fashion.
