  1. 1. Lauren Dreghorn-carver Meteorology Mrs.Joseph/mrs.Neisen
  2. 2. Adiabatic temperature changes and expansion and cooling Air expand-it cools and air compressed-it warms. Rate of adiabatic cooling or heating in unsaturated air is the dry adiabatic rate. When it is saturated air its called wet adiabatic rate and that drys slower then the dry 06/
  3. 3. Orographic lifting /?n=weather It occurs when elevated terrains Mountains act as a barriers air flow that is forcing air to ascend
  4. 4. Frontal wedging /wc.notes/4.moisture.atm.stability/fro ntal_wedging.htm It’s a boundary between colliding masses of warm and cold air It occurs at a front in which cold dense air acts as a barrier
  5. 5. convergence uides/mtr/cld/dvlp/cnvrg.rxml Its lifting of air Results from air in the lower atmosphere That makes it flow together
  6. 6. Localizedconvection lifting•Lifting occurs when unequalheating of earths surface  Link•It warms a pocket or air more the surrounding air .html•Lowering the pocket of airdensity
  7. 7. Stability (density differences andstability and daily weather ation/hanoi/weather-by- month/hanoi-weather-in-august.html Tend to remain the original position when unstable air rises Its most stable condition Is when air temp. increase When that happens it is called temperature inversion
  8. 8. Condensation port/condensation%20page%20for%20unit. html For it to form it needs to have dew,fog,or clouds and the air must be saturated Air above ground turn into tiny particulars matter that is called condensation nuclei It serves as a surface for a water vapor
  9. 9. Types of clouds er/cloud3.html They are classified how they are classified is their shape and height They are cirrus and cumulus and stratus Cirrus –white high thin .cumulus-round individual ,stratus-sheets
  10. 10. High clouds louds3.htm Three family clouds make up the high clouds cirrus and cirrostratus and cirrocumulus All high clouds are thin and white and are often made up of ice crystals They are not considered precipitation makers
  11. 11. Middle clouds ddle%20clouds.htm They are larger and denser. They are part of the altocumulus Light snow or drizzle will accompany them
  12. 12. Low clouds louds1.htm 3 members –stratus and stratocumulus and nimbostratus Fog like layer of clouds Nimbostratus are the stable conditations
  13. 13. Clouds of vertical development Principles.html Some of the clouds do not fit into the height categories They have their bases The clouds are related to each other
  14. 14. Fog (by cooling and byevaporation) vection-fog-in-new-hampshire.html Physically there is no difference between fog and a clound Fog can form on cool clear and calm nights When cool air moves across warm water it may evaporate
  15. 15. Cold cloud precipitation(bergeronprocess) http://nanopatentsandinnovations.blfacts pollen-matters-for-cloud.html Bergeron process is a theory It relates to precipitation Super cooled and freezing nuclei and the different saturation levels of ice and liquid water
  16. 16. Warm cloudFact html Air saturated with respect to water it is super saturated with respect to ice Collision coalescence is a theory of raindrop formation in warm clouds Large clouds collide and join together with smalle droplets to form raindroplets
  17. 17. Rain and snow ke-rain-and-snow-darryl-kravitz.html Light fluffy snow makes individual 6 sided crystals Temps warmer then -5 ice crystals go into large clumps Snowfalls of the snowflakes are heavy ,are high moisture contents
  18. 18. Sleet glaze and hail sciences/the-mysteries-of-earth- science-rain-snow-and-hail/ Sleet-small particles of clear to translucent Glaze-also knew as freezing rain it happens when super cooled raindrops Hail- produce cumulonimbus cloud hailstones are small ice pellets but they get larger s they collect super cooled water cooled
