    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

DIRECTIONS:

This activity can be done either of two ways: by having students work with printouts from materials on the Web, or by directly accessing Web pages on the Internet.

Directions for completing the activity by having students access Web pages on the Internet

Getting Started:
  1. Go to the Windows to the Universe website at www.windows2universe.org
  2. Select Our Planet.
  3. Select Atmosphere. Be sure to select "Advanced" from the reading level options. (Blue button bar near top center of page)
  4. Click on the link to the layers of Earth's atmosphere.
  5. Complete the student worksheet as directed in the following procedures.
Completing the Assignment:
  1. To complete Data Table 1, click and read each of the following sections. After reading each section, use your web browser's “Back” button to return to the "Layers of the Earth's Atmosphere" page.
    1. Troposphere
      1. Click on the image to view the enlarged version of the "Average Temperature Profile of Earth's Atmosphere" graph.
    2. Stratosphere
      1. Ozone in the Stratosphere
    3. Mesosphere
    4. Thermosphere
      1. Ionosphere
      2. Regions of the Ionosphere
      3. The Sun's Effect on the Ionosphere
    5. Exosphere
  2. To complete Data Table 2, view the image The Average Temperature Profile of the Earth's Atmosphere. Be careful when reading the graph - you are asked for the maximum temperature in each layer, which will be a position farthest right. Also, you need to remember to read the image from the bottom up as the image starts with an altitude (y-axis) of 0 (ground level) and continues up. To complete the 'Ionosphere' part of Data Table 2, you will need to read Different Regions of the Ionosphere. Find the altitudes between which the ionosphere exists, calculate the thickness then go to The Average Temperature Profile of the Earth's Atmosphere to determine the maximum temperature of the ionosphere.
  3. To complete Data Table 3, continue to refer to The Average Temperature Profile of the Earth's Atmosphere. Pay close attention to what is happening to the temperature as you travel from the bottom of a layer to the top of the same layer.
  4. To complete the Analysis Questions, click on related reading topics.
    1. Question 1: The Average Temperature Profile of the Earth's Atmosphere
    2. Question 2: Stratosphere
    3. Questions 3 & 4 Ozone in the Stratosphere
    4. Question 5: Thermosphere
    5. Question 6: Ionosphere
    6. Questions 7 & 8: Regions of the Ionosphere
    7. Questions 9 & 10: The Sun's Effect on the Ionosphere
