Clouds and precipitation project

  1. 1. By: Erinne FinlaysonCLOUDS AND PRECIPITATIONPROJECT
  2. 2. Adiabatic Temperature Changeand Expansion and Cooling When air expands it cools but when air is compressed it warms. The dry adiabatic rate is when cooling and heating only affect unsaturated air. Farther off the earths surface the less pressure. http://www.kidsgeo.com/geography-for-kids/0070-adiabatic-temperature-changes.php
  3. 3. Orographic Lifting Mountains act like walls to air flow causing Orographic lifting. Windward side of mountain will be rainy. Leeward side will be dryer. http://www.examiner.com/outdoorsman-in-salt-lake-city/understanding-why-utah-has-the- greatest-snow-on-earth-part-1-orographic-lifting
  4. 4. Frontal Wedging Cool and warm air collide producing fronts. Cooler air is more dense than warm air. Cool air asks like a wall against warmer air. http://www.harding.edu/lmurray/113_files/HTML/d2_Earth%20Revised/sld0 46.htm
  5. 5. Convergence The different air masses force air to rise. Convergence is when the lower atmosphere mix together. Florida peninsula is a good example. http://keithrogershome.com/Chap8Clds.html
  6. 6. Localized Convective Lifting Warmed air Warm parcles of air rise and form condensation clouds. May cause rain showers. http://rst.gsfc.nasa.gov/Sect14/Sect14_1c.html
  7. 7. Stability  Unstable air moves up  Stable air dose not  Unstable air= Thunderstorms maybe even tornadoshttp://www.richhoffmanclass.com/chapter4.html
  8. 8. Condensation Water vapor changes to liquid. (Gas to liquid) Air must be saturated Results in dew, fog, or clouds. http://www.scottslumber.com/services/window- condensation-are-my-windows-defective/
  9. 9. Types of Clouds Clouds are formed by form and height. Types  Cirrus (curl of hair) is seen as a white cloud.  Cumulus (a pile) is seen as rounded separate cloud masses. Cauliflower structure.  Stratus (a layer) seen as sheets or layers that cover most or all of the sky. http://ed101.bu.edu/StudentDoc/c urrent/ED101fa10/jenmks/
  10. 10. High Clouds Found over 6,000 meters off of earths surface. Cirrus and Cirrostratus are two possible clouds found as a high cloud. Warning of stormy weather coming. http://www.zastavki.com/eng/Nature/Clouds/wallpaper-14253.htm
  11. 11. Middle Clouds Found around 2,000-6,000 meters off of earths surface. These clouds are white or gray. They warn of a little snow or drizzle. http://acrosstheuniverse.forummotion.com/t862-i-ve-looked-at-clouds-from-both-sides-now
  12. 12. Low Clouds Seen as rainy clouds Located below 2,000 meters from the Earth’s surface. Created when air is forced up. Stratus and Stratocumulus are some clouds that can be found here. http://bmvgallery.com/tag/clouds/
  13. 13. Clouds and Vertical Development Made up of unstable air These clouds cause showers and thunderstorm. A upward movement is strong enough to give many clouds a great vertical rang form. http://www.uwgb.edu/dutchs/EarthSC102Notes/102Clou ds.htm
  14. 14. Fog Fog and clouds are the same thing, they are just created in different place. Fog is the cooling or movement over something cold. Fog is found very close to the ground. http://helicopterblog.com/?p=276
  15. 15. Cold Cloud Precipitation It the ground is 0 degrees Celsius it must be at least -40 degrees Celsius in the clouds to create snow, hail, ext. When ice crystals contact cloud drops they cause them to freeze. Supper cold water will freeze if it impacts the ground. http://nasasport.wordpres s.com/2011/08/26/amsr-e- maps-rain-associated- with-irene/
  16. 16. Warm Cloud Precipitation When water absorbing partials remove water vapor from air at relative humidity. Salt can remove water vapor from the air. Tropics is an example of warm cloud Precipitation http://hdwallpapersdesktop.com/wallpapers/2011/08/wallpaper-ocean-tropics-clouds-boat-island-yacht- photo/wallpaper-ocean-tropics-clouds-boat-island-yacht-photo-2/
  17. 17. Rain and Snow Rain- drops of water that falls from clouds. Must be a least .5mm. Snow- made up of separate 6-sided crystals. Warmer that -5 degrees Celsius, ice crystaly join in large clumps. http://totallycoolpix.com/2011/01/us-east-coast-snow-storms/
  18. 18. Sleet, Glaze and Hail Sleet-small particles of clear-to-translucent ice. Glaze- Freezing rain that was freezing before hitting objects. Hail- cumulonimbus clouds ice pellets. http://www.erh.noaa.gov/cle/wx_events/2008/2008end.php
