### Moisture,clouds,and precipitation

1. 1. Christian Dumberth

3. 3. Orographic lifting is when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. It is when air is forced to go with the terrain http://www.waterencyclopedia.com/Ce- Cr/Climate-Moderator-Water-as-a.html http://en.wikipedia.org/wiki/File:Orogra phic_lifting_of_the_air_-_NOAA.jpg
4. 4. Front A front is a boundary between a cooling body mass of hot air and cold air. A frontal wedging is ware the cold air is in the fronthttp://www.windows2universe.org/earth/Atmospher e/tstorm/occl_front.html http://keithrogershome.com/Chap11Fronts.html
5. 5.  Convergence is the natural heating and culling of the surface. Hot air rises cold air sinks Hot air rises because it is less dens Cold air sinks because it is more dens http://clem.mscd.edu/~wagnerri/CloudDevel opment.htm
6. 6.  Localized convection is when hot air rises in a pocket of les dens air and snicks as more dens cold airhttp://en.wikipedia.org/wiki/Convection
7. 7. Stable air stays in its original position, wile unstable air rises the most stable conditions for the air is when air temperature actually increases with height it Is called a temperature inversion. http://www.airphotona.com/image.asp?imag eid=14226&catnum=0&keyword=&country= &state=&pagenum=556 http://www.targetarea.net/var05.html
8. 8. For condensation to happen the air must be saturated to make dew, fog, or clouds When air is saturated the water vapor condensates on to dust witch is called condensation nucli.http://decorating.visitacasas.com/how-to- combat-condensation/
9. 9. Clouds are classified on the basis of there form and height. Cirrus clouds are high White and thin. They can happen as patches or look like fluffy blankets in the sky. Cumulus clouds are single round cloud masses with a flat base and a appearance that seams like it is rising. Stratus clouds are the clouds that cover the sky completely with small or no brakes in it. With no individual cloud in it http://en.wikipedia.org/wiki/File:CirrusField-color.jpg http://www.usatoday.com/weather/wcumulus.htm http://urbanext.illinois.edu/kalani/18.cfm
10. 10.  The high clouds are called cirrocumulus cloud and there are three clouds that make up the high cloud they are the cirrus, cirrocumulus, and cirrostratus clouds. It is 6000m in the air All high clouds are thin and white and often made of ice crystals http://eo.ucar.edu/kids/sky/clouds3.htm
11. 11.  The middle clouds also known as the altocumulus cloud they can change there form in different conditions They are 2000, 6000 meters in the air They can be a Wight or gray with an infrequent light snow or drizzle mar accompany the cloudshttp://www.bigbranch.net/middle%20clouds.htm
12. 12.  There is three types of low clouds stratus, stratocumulus, and nimbostratus. The stratus cloud is a fog like layer that always cover the sky. When the cloud gets uneven it becomes an a stratocumulus cloud A nimbostratus cloud is the clouds that produce precipitation http://ed101.bu.edu/StudentDoc/current/ED101fa10/j enmks/stratus.html http://www.tariqweb.com/2011/03/04/stratocumulus- clouds/ http://en.wikipedia.org/wiki/File:June_2005_dark_clo ud.jpg
13. 13.  Clouds that don’t fit in the three height categories The clouds with vertical development are filed with unstable air and all of them are related to another. They can also produce rain http://www.wbsg.org/weather/weather_clou ds.asp
14. 14.  It starts when the earth cools off rapidly bye radiationhttp://www.scoutingny.com/?m=201008
15. 15.  When the temperature is 4c snowflakes usually melt and continuo as rain drops When the temperature is -5c ice crystals join into larger clumps and form a snow flake. http://www.shutterstock.com/pic- 47930068/stock-vector--glossy-icons- representing-different-weather-symbol-sun- clouds-rain-storm-snow-night.html
16. 16.  Sleet is the fall of small particles of clear transparent ice. Glaze also known as freezing rain it happens when rain becomes 0c and when it hits a surface I turns into ice. Hail is produced in a cumulonimbus cloud it starts as a small ice pellets that grow by collecting super cooling water as they fall.
