Welcome to class!

Weather engulfs us. Its influence can be both dramatic and subtle. Weather tempers how we dress, how we live, the music we play, and the art we create. It can destroy our homes and threaten our lives. It affects our daily activities, leisure, holidays, transportation, commerce, agriculture, and nearly every aspect of our lives. Our fascination with the weather has led to 24-hour weather networks, feature-length motion pictures, and an explosion of detailed weather data over the Internet. Weather and its ever-changing nature has always drawn the attention of people and at times altered their lives. 

Mark Twain said "everyone talks about the weather, but nobody does anything about it". You may not be able to change the weather, but you can discover the processes that determine weather. Learning about meteorology can and should be both enjoyable and relevant to your everyday life. Knowledge gained from this class can help you better understand nightly television weather reports and interpret news articles on impending climate change, greenhouse warming, the depletion of the ozone layer, the causes and effects of El Niņo, and severe weather. You will experience and be influenced by these events throughout your lifetime and this class will help you to grasp the fundamentals and gain an appreciation of the complexities involved with these issues.

PRE-CLASS Assessment will not be availalble until the second week of class. Check-your grade will not be available until after the add/drop period.

Reading Assignments
