    Clouds and precipitation project Clouds and precipitation project Presentation Transcript

    • By: Taylor Bauman
    • Adiabatic Temperature Changes Happens when air is compresses or expanded. When it expands it cools and when it compresses it warms. As you travel up in the atmosphere the atmosphere pressure decreases because there are fewer and fewer gas molecules.http://www.kidsgeo.com/geography-for-kids/0070- adiabatic-temperature-changes.php
    • Orographic Lifting When elevated terrains act like barriers for air to flow. If air descends, it warms adiabatically, then it makes condensation and precipitation even less likely.http://www.nc-climate.ncsu.edu/edu/k12/.LiftingMechanisms
    • Frontal Wedging  Associated with specific storms called middle-latitude cyclones.  Cooler, denser air acts as a barrier over the warmer, less dense air that rises.http://www.wou.edu/las/physci/taylor/gs106/atm2_precip_files/frame.htm#slide0004.htm
    • Convergence  Air in lower atmosphere flows together.  Florida experiences the greatest number of mid- afternoon thunderstorms.http://certik.github.com/femhub.org/
    • Localized Convective Lifting  On warm summer days, unequal heating of the Earth’s surface may cause pockets of air be warmed more than the surrounding air.https://www.meted.ucar.edu/sign_in.php?go_back_to=http%253A%252F%252Fwww.meted.ucar.edu%252Fdot%252Fprint.htm
    • Stability Stable air tends to remain in its original position, while unstable air tends to rise. Measured by the temperature of the atmosphere at various heights. http://serc.carleton.edu/introgeo/models/E qStBOT.html
    • Condensation Air must be saturated. Water vapor in air turns to liquid. Occurs at dew point.http://decorating.visitacasas.com/how-to-combat-condensation/
    • Types of Clouds  Classified by their form and height.  3 types: Cirrus, Cirromulus, Cirrostratus.http://www.usatoday.com/weather/wcirrus.htm
    • High Clouds Cirromulus consist of fluffy mass. Cirrostratus clouds are flat layers. http://cloudjournal.blogspot.com/2007/11/c ross-winds.html
    • Middle Clouds  Altocumulus clouds consist of a rounded mass, larger and denser.http://www.ifimages.com/public/image/139051/view.html
    • http://www.colby.edu/cpse/equipment2/higLow Clouds hclouds/high.html 3 members: Stratus, Stratocumulus, and Nimbostratus. Uniform, fog-like layer.
    • Clouds of Vertical Development Bases are in low height range but extend upward. They are all related and have unstable air. http://www.pilotfriend.com/av_weather/me teo/clouds.htm
    • Fog ( by cooling and by evaporation)  Fog is a cloud with its base at or very near ground.  Fog can form on cool, calm, clear nights.http://www.physicalgeography.net/fundamentals/8f.html
    • http://ocw.usu.edu/Forest__Range__and_W ildlife_Sciences/Wildland_Fire_Managemen t_and_Planning/Unit_4__Temperature- Moisture_Relationship_7.htmlCold Cloud Precipitation Bergeron process relies on two physical processes: supercooling and supersaturated. Liquid below 0 degrees Celsius is said to be supercooling.
    • Warm Cloud Precipitation The thing that forms raindrops is called the collision- coalescence process. As the raindrops move they join together with smaller, slower droplets. http://www.srh.noaa.gov/fwd/?n=warmrain paper
    • Rain and Snow The term rain means droplets that fall from a cloud and a diameter of at least 0.5 mm. (smaller droplets are called drizzle) At very low temperatures light, fluffy snow made up of 6 sided ice crystals. http://www.its.caltech.edu/~atomic/snowcr ystals/photos/photos.htm
    • Sleet, Glaze and Hail  Sleet is the fall of small particles of clear ice.  Glaze also known as freezing rain happens when raindrops become supercooled.http://www.alabamawx.com/?tag=sleet
