Clouds and precipitation

  1. 1. Clouds and Precipitation By: Cullen Williamson
  2. 2. Adiabatic Temperature Changes and Expansion and Cooling adiabatic-temperature-changes.php • It is when temperatures change even though no heat is added or taken away • When air expands it cools and when it gets compressed it
  3. 3. Orographic Lifting temperature-changes.php • When mountains block air flow and the air goes up the mountain slope and adiabatic cooling makes clouds and precipitation
  4. 4. Frontal Wedging m.stability/frontal_wedging.htm • When colder and denser air makes warmer and less denser air rise
  5. 5. Convergence ouds.htm • Whenever air in the lower atmosphere goes together and results in lifting
  6. 6. Localized Convective Lifting • Unequal heating of the Earth causes air pockets to be warmed more than the air surrounding it. The pockets are called thermals and the process that produces them is called localized convective lifting
  7. 7. Stability nces/Wildland_Fire_Management_and_Planning/Unit_ 7__Atmospheric_Stability_and_Instability_1.html • Stable air remains in the same spot it is in and unstable air rises
  8. 8. Condensation port/condensation%20page%20for%20unit.html • For condensation to happen, the air has to be saturated first
  9. 9. Types of Clouds u_sch_stacey_ksg_3/em/ch9.html • Clouds are named on what they look like and how big they are • Cirrus, cumulus, stratus
  10. 10. High Clouds s/cw/au_sch_stacey_ksg_3/em/ch9.html • Cirrus, cirrostratus, cirrocumulus • They are thin and white and often made of ice crystals
  11. 11. Middle Clouds hools/cw/au_sch_stacey_ksg_3/em/ch 9.html • Have “alto” in front of the name • Infrequent light snow or drizzle might be with them
  12. 12. Low Clouds hools/cw/au_sch_stacey_ksg_3/em/ch 9.html • Stratus, stratocumulus, nimbostratus • Fog-like layer that covers a lot of the sky • The might produce light precipitation
  13. 13. Clouds of Vertical Development b-yt.html • Low height range but can extend upward into middle or high altitudes • Cumulonimbus create rain showers or thunder storms
  14. 14. Fog 0/11/fog-at-flatwoods-pt-i.html • Defined as a cloud with its base at the ground • When cool air moves over warm air, moisture will evaporate and produce saturation as the rising water vapor meets the cool air and it condenses and looks like steam
  15. 15. Cold Cloud Precipitation 1/12/sandbox-comments-summit-county- citizens_08.html • Supercooled and supersaturated • Supercooled water will readily freeze if it hits the ground
  16. 16. Warm Cloud Precipitation 04_03_lecture_files/frame.htm • Collision-coalescence process is the thing that make rain drops • Water absorbing particles remove water vapor from the air at relative humanities less than 100% forming drops that are big.
  17. 17. Rain and Snow on-of-a-raindrop/ • Raindrops have a diameter of at least .5 mm • At temperatures warmer than -5 degrees C, ice crystals join together into large packs and have high moisture
  18. 18. Sleet, Glaze, and Hail • Sleet is ice that is clear or translucent • Glaze is when rain becomes supercooled and turn to ice when impacting the ground • Hail is small pieces that grow when supercooled water droplets join it
