Clouds and precipitation

  1. 1. Clouds and Precipitation By: Nic Gildner
  2. 2. Adiabatic Temperatures changes• Adiabatic is referring to any process that occurs without heat transfer.• This is also a concept used in many areas of engineering and physics.
  3. 3. Orographic Lifting• The vertical movement of air.• Happens on the windward side of a mountain.• Forcing the air to ascend, or move upward. m815/Cases/HCR/HCR.html
  4. 4. Frontal Wedging• Boundary of colliding masses of cold and warm air.• Also a process occurs in the front that is cold dense air.• Warmer less dense air rises. back_to=http%253A%252F%252Fwww.meted. %252Fprint.htm
  5. 5. Convergence• Lifting of air• Results of the air in the lower atmosphere• With they both flow together• mtr/cld/dvlp/cnvrg.rxml
  6. 6. Localize Convective Lifting• Occurs when there is unequal Heating on the Earth.• Warms a pocket of air more then surrounding air.• Lowering the air density.
  7. 7. Stability ( Density Differences & Stability and Daily Weather• Happens when air temperature increases with height.• Called temperature inversion l
  8. 8. Condensation• Gas to liquid• Warm air can hold more moisture then cold air• Condensation can damage a car. http://www. istockphoto. com/stock- photo- 56605-cold- glass-of- water-with- condensatio n.php
  9. 9. Types of Clouds• Cirrus clouds are high, white and thin clouds• Cumulus consist of rounded individual cloud masses• They have flat bases and appearance over domes or stadiums 04/different-types-of-clouds.html
  10. 10. High Clouds • The bases are usually dark • High Clouds are called cirrus • High Clouds usually don’t produce precipitation
  11. 11. Middle Clouds• Made of ice crystals‘ and water droplets.• Middle Clouds can go up to 2000 to 8000m http://braindancei sawayoflife.blogsp oudspotters- guide.html
  12. 12. Low Clouds• Stratus up to6500• Lower clouds have puffy layers• And they are very common around the world http://braindanceisaw 2009/04/cloudspotter s-guide.html
  13. 13. Clouds of Vertical Development• Consist of different cloud types.• This occurs when warm air rises• They also have patterns to them. http://www.teachengine hp?url=http://www.teac ion/cub_/activities/cub_ air/cub_air_lesson04_ac tivity4.xml
  14. 14. Fog (by cooling an evaporating)• A collection of liquid water droplets and ice crystals that form on the earth surface.• A form a cloud that is very close to the ground.
  15. 15. Cold Cloud Precipitation ( Bergeron process)• Also known as the cold rain ice crystals process.• When is crystals form in higher clouds then usual..• Water goes from liquid to vaper g/EastCoastWeather/archive.html?y ear=2005&month=12
  16. 16. Warm Cloud Precipitation• Is when air rises• Also the warm air would go above the colder air.
  17. 17. Rain and Snow• Snow only occurs when it is blow frezzing• Rain occurs when the clouds are closer to the ground then further away. /snow-showers-possible-in-highest-elevations- late-thursday-night/
  18. 18. Sleet, Glaze and Hail• Sleet is frozen rain. 1/zuppa-toscana.html• Glaze is a thin coding of ice.• Hail is form of huge blocks of ice
