Climate System and Weather Climatology Lesson 1 Weather Weather refers to: The state of the atmosphere in a particular place and time. Weather occurs over short time periods. The weather predictions usually cover days or weeks. Types of Weather • What terms do you associate with weather? What Causes Weather? • Weather is an expression of the climate system. • The climate system is the interaction of the atmosphere, biosphere, and other parts of the Earth that determine weather at a time or place The Biosphere The Atmosphere The Oceans Temperature Difference From Normal (°C) Studying Climate Involves Long-term Trends http://data.giss.nasa.gov/gistemp/graphs/ Relating Climate and Weather -What do the thick red and thick blue lines represent? -What do the fluctuating red and blue lines represent? Why is the Climate System Important? • The climate system determines the weather. The weather affects many of our daily decisions. • Climate affects long-term decisions by humans. • Climate affects long-term trends in plants and animals. What do you think? • The following video talks about weather, climate, and climate change. • While watching the video, think about whether the terms weather and climate are used appropriately given the definitions. Click Here for Video Link Video Discussion • What was the viewpoint of Stephen Colbert in this video clip? • In what ways were the terms weather, climate and climate system referred to improperly? • Discuss the main evidence for support of climate change in spite of heavy snowfall. Weather or Climate? • With your group, watch each of the following video clips and decide if they are examples of weather, climate or could they be both? Be prepared to defend your group’s response. • • • • • Tornado: http://www.youtube.com/watch?v=oJlfAGC8G8w&feature=relmfu Drought: http://www.youtube.com/watch?v=u9s_A0G7oUU&feature=related Rainstorm: https://www.youtube.com/watch?v=ugK4AsMEVsg Blizzard: https://www.youtube.com/watch?v=gqi0K1CaWXI&feature=related Wildfire: http://www.youtube.com/watch?v=yujOhGio_BE
