3 Regional Gliding School The Atmosphere From the standpoint of weather, water vapour is the most important component of the air. COMPOSITION: Made up of invisible gases. These gases are: a)Nitrogen78% b)Oxygen21% c)Other 1% (Argon, carbon Dioxide, water vapour, etc.)

4 Regional Gliding School Properties of the atmosphere A)Mobility B)Compression C)Expansion The most important property of the atmosphere is expansion. These in combination are the cause of almost all atmospheric weather phenomena.

6 Regional Gliding School A B C D 21 62 78 1 Let's try a few review questions on Meteorology: Question #1 - What percentage of nitrogen makes up the atmosphere? Meteorology Properties of the Atmosphere

16 Regional Gliding School  Temperature and pressure decrease with height.  Lowest layer of the atmosphere.  Most weather occurs here!  Top layer is known as Tropopause. Here the temperature stops dropping. Troposphere Divisions of the Atmosphere

17 Regional Gliding School  Pressure still decreases but temperature continues to increase gradually to zero degrees Celsius.  Water vapour and air currents are almost non-existent.  Top layer is called Stratopause. Stratosphere Divisions of the Atmosphere

18 Regional Gliding School  Marked increase in temperature that reaches 10°C. This is due to presence of the ozone layer (the ozone layer absorbs radiation from the sun).  Top layer is called Mesopause.  Temperature drops rapidly to -100 °C at the Mesopause. Mesosphere Divisions of the Atmosphere

19 Regional Gliding School  Thermosphere is the highest layer of the atmosphere.  Temperature continues to rise in the thermosphere.  The Ionosphere is located within the thermosphere and reflects low and medium frequency waves affecting radio communications. Thermosphere Divisions of the Atmosphere

20 Regional Gliding School  Layer wherein the pressure drops to little more than a vacuum  The spectacular auroras (Northern Lights) form in this region  Bottom is undefined and is located at 500 km above the surface of the earth. Exosphere Divisions of the Atmosphere

21 Regional Gliding School  Very difficult to define because of density  The temperature can rise as high as 3,000 degrees Celsius at 600 kilometers Space Divisions of the Atmosphere

22 EQUATOR N S 55,000’ - 65,000’ 25-30,000’ TROPOSPHERE STRATOSPHERE MESOSPHERE THERMOSPHERE DIVISIONS OF ATMOSPHERE The divisions are primarily based on the temperature of each layer

34 Regional Gliding School Congratulations!! You have now completed the Properties of the Atmosphere lesson of the Meteorology Module. Of course, this lesson is always available to you for future reference if required. You are now ready to move along to the next Meteorology lesson you have not completed or to any other module you wish. You can advance to the Self Test Module if you feel ready to challenge the final exam. Good Luck! Meteorology Properties of the Atmosphere
