  1. Clouds • Form because air becomes saturated • Warm air rises and cools resulting in condensation and cloud formation • Composed of an aggregation of moisture droplets • When enough droplets are accumulated it can rain • Clouds will only form at or above the condensation level

  2. Cloud types • Defined by altitude and shape • Stratiform • Horizontal flat clouds • Cumuliform • Puffy clouds • Cirroform • Wispy

  3. Cirrus – high thin cloudsMADE OF ICE CRYSTALS WHAT SEASON USUALLY? AND WHAT PRESSURE???

  4. High Clouds (Cirrus) Ice only > 6 km

  5. Cumulus – fair weather clouds

  6. Middle clouds (Altocumulus) Ice and water 2 to 6 km

  10. Odd clouds LENTICULAR CLOUD (or spaceship?)

  11. Odd clouds PILEUS
