1. First we need to learn about air masses. Visit this link: http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/af/arms/home.rxml to discover the definition of an air mass.
2. Now we need to learn the types of air masses, where they form, and the characteristics of the air in each. Visit this link: http://www.usatoday.com/weather/tg/wamsorce/wamsorce.htm to achieve this objective and learn which air masses affect us in the U.S.
3. Now that you know the types of air masses, click on this link: http://www.wunderground.com/ and see if you can identify the types of air masses that are present in the U.S. today by clicking on Temperature and Humidity next to the map and comparing the two views. Use a pencil and try to draw these air masses on the map provided to you.
4. Ok, now that we made it this far it is time to learn about fronts. Click on this link: http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/af/frnts/home.rxml to find the definition of a front.
5. Now click on the following links to learn about the types of fronts, their symbols, and the weather they bring.
6. Now click on this link to see a nifty animation and learn why cold fronts bring the weather they do: http://apollo.lsc.vsc.edu/classes/met130/notes/chapter11/graphics/59_Cold_Front/59.html
7. Click on this link to see a nifty animation and learn why warm fronts bring the weather they do: http://apollo.lsc.vsc.edu/classes/met130/notes/chapter11/graphics/58_Warm_Front/58.html
8. Now revisit this site: http://www.wunderground.com/ and click on fronts. Is there a correlation between where you placed the air masses on your map and where the fronts are located? Draw the fronts on your map.
9. Looking at the same map, what will the weather be like in the next 24-48 hours. It may help if you click on animate under the map. Write down your prediction.
10. As a final project, you are to write a 5 paragraph essay describing the impact of air masses and fronts on our weather. The paper should be at least 1 1/2 pages in length and if typed (preferred) should be in 12 pt. Times New Roman font and double spaced. See the rubric under EVALUATION for information on grading.
