  • 1. Clouds: the basics
  • 2. Formation
    • Three requirements for clouds to form
  • 3. Moisture
    • There must be sufficient water vapor in the air to build a cloud.
    • In the Cloud in a jar experiment this was provided by the boiling water
  • 4. Cooling Air
    • The air temperature must decrease enough for water vapor to condense.
    • (You see snow on mountain tops because it is cooler at high altitudes…. Clouds form high in the sky because the air is cooler up there)
    • The ice and the cold jar accomplished this in our experiment
  • 5. Condensation nuclei
    • Simpler than it sounds
    • Tiny particles, invisible to the human eye, such as dust, dirt, and pollutants, provide surfaces on which water molecules can gather and condense into water droplets.
    • The smoke provided the tiny particles in the Experiment
  • 6. Types of Clouds
    • Many different classification
    • Altitude
      • Cirrus – High
      • Alto – Mid
      • Stratus - Low
    • Nimbus/Nimbo: associated with precipitation
    • Cumulus fluffy
  • 7. Stratus
    • Also means layered clouds (flat)
  • 8. Cumulus
    • Clumpy puffy clouds
  • 9. Cirrus
    • composed of ice crystals
    • Thin and wisplike strands
  • 10. Cumulonimbus Clouds
    • much larger and more vertically developed than fair weather cumulus
    • Are associated with powerful thunderstorms
  • 11. Many more
    • alto-cumulus - Middle-level, medium-sized puffy clouds. alto-stratus - Middle-level, layered clouds. cirro-cumulus - High-altitude, small, wispy, patchy, puffy clouds. cirro-stratus - High-altitude, thin, wispy clouds in layers. cirrus - High-altitude, thin, wispy clouds. cumulo-nimbus - Large, dense, towering clouds that cause thunderstorms. cumulus - Low, puffy clouds. fog - Ground-hugging clouds. nimbo-stratus - Low, dark, rain cloud. stratus - Low, layered, horizontal, wispy clouds with a flat base. strato-cumulus - Low clouds, broad and flat on the bottom, puffy on top (higher than cumulus and lower than altocumulus).
