Student Objectives: Become acquainted with the fundamentals of meteorology, including historical considerations, basic physical laws, elements of weather, meso and global scale processes, and observation and forecasting of the weather, develop a greater understanding and appreciation of the behavior of the atmosphere. Develop the ability to synthesize information, concepts, and laws relating to meteorology toward the goal of solving problems or assessing given situations in a critical and scientifically sound manner.

Attendance: Class attendance is required for all quizzes, exams and class presentations.

 Course Grade Total Points A 360 or above A- 347 – 359 B+ 333 – 346 B 320 – 333 B- 307 – 319 C+ 293 – 306 C 280 – 292 D 240 – 279 F less than 240

Course Structure

This course in introductory meteorology is built around the idea of progressing from information and concepts to synthesis to understanding.

[ information + concepts ] --> synthesis --> understanding

The course will consist of three major parts each occupying four weeks. During those four weeks class time will be partly devoted to lecture on specific topics, lab exercise, and question/answer and discussion sessions. The lectures will focus on details of important topics; however the bulk of background information must be obtained from readings in the textbook and other sources. As a stimulus for discussion periodic homework assignments will be made. Class time, lab work, and homework are designed to prepare the student to bring the concepts and information together and develop a logical and scientifically tenable presentation in the form of a synthesis report. The synthesis report will be based on projects carried out in the lab portion of the course. The report should demonstrate an understanding of concepts and show the ability to apply them in a creative manner. The report should use the concepts and factual information in a way that demonstrates understanding.
