Atmosphere

Part A. The atmosphere is comprised chiefly of nitrogen, oxygen and several trace gases. Discuss fully its gasses with an emphasis on why these gases are important. To what extent does Earth’s gravity compress these gases?

Part B. The atmosphere is also divided into four layers based on an oscillation between the normal and inverted lapse rates. Define a normal and inverted lapse rate. Then describe the four layers noting their altitudes and their importance

Atmosphere

How are the instruments below used to understand atmosphere and weather information?
http://climate.ncsu.edu/edu/Instruments

a) Models of atmospheric structure-(http://celebrating200years.noaa.gov/magazine/modeling_101/welcome.html

b) Research balloons- https://www.weather.gov/bmx/kidscorner_weatherballoons
https://scied.ucar.edu/weather-balloons

c) Ozone and absorption of radiation- https://ozonewatch.gsfc.nasa.gov/facts/ozone_SH.html

B. AKQ1b: Why is it important to understand characteristics of the atmosphere?

  1. How does radiation coming in and going out interact within the troposphere and stratosphere? http://www.windows2universe.org/earth/Atmosphere/earth_atmosph_radiation_budget.html
  2. Explain the Earth’s energy budget (We will do this in a separate activity)
  3. The importance of the troposphere for weather and human activity.

C. AKQ2a: What is the pattern of air movement in the troposphere? (How do the following affect tropospheric air movement?) This link can cover many of the items below.

  1. Global insolation- View and take notes on this Bitesize guide, take the test and record your score: https://www.bbc.co.uk/bitesize/guides/z24rr82/revision/1#:~:text=Insolation%20is%20solar%20radiation%20received,by%20particles%20in%20the%20air.
  2. High and low pressure. (Temperature and pressure distribution/seasonal variation)
  3. Global and local winds-
  4. Effect of land, relief and ocean currents on air movement.
