So I want to offer you a pretty simple resource- different ways to visualize weather in graphical forms.
Firstly, our weather maps, presented by your local news station or weather.com are absolutely graphs! They show information both numerically and by color scales. Below are examples of Average Normal Temperature maps for the continental United States.
Right away we're illustrating the second point, that climate is varied in different parts of the world and when you add in different months, we're illustrating the first, that weather changes seasonally in one area. How could your class transfer the twelve or twenty four maps into graphs? Rather than distilling by month, you can distill by latitude, state or month.
A second resource for weather visualizations in weatherspark.com. This website is tremendously useful because you can find both maps and graphs for a wide variety of weather variables in locations all over the world.
Both weather.com and Weather Spark have maps and charts with temperature and precipitation, but weather spark also offers data about probability of precipitation, snow fall, daylight hours, wind speed, wind direction, relative humidity and more. There are lots of variables to chose from, clear information about where the data comes from and a diversity of locations. Explore the options and let us know what you think.
