  1. 1. By: Ben King
  2. 2.  When air is heated it becomes less dense as a result lighter  It rises upward above the cool air  Air expands because there’s less amount of pressure higher up in the atmospherehttps://www.meted.ucar.edu/sign_in.php?go_back_to=http%253A%252F%252Fwww.meted.ucar.edu%252Ffire%252Fs290%252Funit6%252Fprint.htm
  3. 3.  It means a topographic uplift and forced land lifting When this type of lifting happens the land forces the air to move to a higher elevation The temperature of the air cools as is it is lifted up higher in the atmospher http://www.waterencyclopedia.com/Ce-Cr/Climate-Moderator-Water-as- a.html
  4. 4.  When warm air and cool air collide Warm air is less dense then cooler air so it’s wedged upward. This ends up causing fronts that usually means rain.
  5. 5.  Whenever air in the lower atmosphere flows together, lifting results Air flows in different directions, it has to go somewhere so it goes up It can lead to adiabatic cooling and cloud formationhttp://10.85.0.4:8080/ibreports/ibp/bp.html?fn=Students&fp=1&ip=10.182.1.49&ibip=10.85.0.4&ldu=0&re=0&bu=www.islandnet.com/~see/weather/elements/whatgoesup3.htm&bc
  6. 6.  Unequal heating of the Earth’s surface may cause pockets of air to be warmed more than the surrounding air The pockets of air that get warmed more will become less dense than the surrounding air will move upward These clouds might produce rain
  7. 7.  Stable air resists vertical movement It won’t get warm, expand, and less dense and rise. But it also won’t cool and become more dense and sink http://ocw.usu.edu/Forest__Range__an d_Wildlife_Sciences/Wildland_Fire_Man agement_and_Planning/Unit_7__Atmos pheric_Stability_and_Instability_1.html
  8. 8.  It happens when water vapor in the air changes to a liquid  This may result in dew, fog and clouds  But for any of those above to happen the air has to be saturated, it occurs when air is cooled to a dew point. Less often when water vapor is added to the airhttp://shoalwater.nsw.gov.au/Education/condensation.htm
  9. 9.  Clouds are classified based on their form and height Cirrus- the clouds are high, white and thin Cumulus- clouds are rounded individual cloud masses Stratus- best described as sheets of paper that cover much of the skyhttp://www.enchantedlearning.com/subjects/astronomy/planets/earth/clouds/
  10. 10.  The types of clouds in this category are cirrus, cirrostratus, and cirrocumulus  Cirrocumulus clouds are fluffy masses and cirrostratus are thin white layers  If a cirrus cloud are fallowed by a cirrocumulus or cirrostratus cloud they may warn of stormy weatherhttp://www.srh.noaa.gov/key/?n=high_clouds
  11. 11.  They range from 2000 to 6000 meters in the air  Altocumulus clouds are rounded masses but Cirrocumulus clouds are larger and denser  Covers the sky may mean a light snow or drizzle may comehttp://www.beijinghikers.com/v2/resources/news/hiking-photos-switchback-great-wall-2009-12-16/
  12. 12.  Consists of stratus, stratocumulus, and nimbostratus clouds  It is a fog like cloud that covers most of the sky and occasionally might show light precipitation  Nimbostratus clouds form the most precipitation and form from air being forced upwardhttp://chr.wikipedia.org/wiki/File:Low_clouds.jpg
  13. 13.  Some clouds do not fit in the three categories  some clouds have bases in the low height range but often extend into the middle or high range  Cumulus clouds with air flowing upward would develop rapidlyhttp://www.uwgb.edu/dutchs/EarthSC102Notes/102Clouds.htm
  14. 14.  Clouds and fog are basically the same except the place formation fogs just a lot lower  Cause by Cooling- a blanket of fog is produced with warm moist air  Caused by Evaporation- when cool air moves over warm water it often evaporates and makes foghttp://www.brainharmonycenter.com/brain-fog.html
  15. 15.  Bergeron process relies on to physical processes: super cooling and super saturation  The temperature in the air needs to be sometimes -40 degrees Celsius but under 0 degrees Celsius is considered super cooled  It would have to be 100% relative humidity but supersaturated is more than 100% humidityhttp://nanopatentsandinnovations.blogspot.com/2010/06/amount-of-dust-pollen-matters-for-cloud.html
  16. 16.  The mechanism for this is collision- coalescence process Some water absorbing-particles can remove water vapor and form drops that are large As they move through the cloud they collide and join together with smaller slower dropletshttp://rst.gsfc.nasa.gov/Sect14/Sect14_1d.html
  17. 17.  Rain means drops of water that fall from a cloud and have a diameter of at least .5 mm. When the temperature is above 4 degrees Celsius the snowflakes continue decent as rain At temperatures are above -5 degrees Celsius they clump together and make snow flakes http://itunes.apple.com/us/app/snow /id287063264?mt=8
  18. 18.  Sleet is the fall of small particles of clear-to- translucent ice Hail is produced in cumulonimbus clouds they begin as small ice pellets Each trip through a super cooled cloud just adds a layer of ice
