Cloud formation - How clouds form and different types of clouds

  1. 1. Cloud formation
  2. 2. Rising Air • Imagine a block of air, or air parcel, rising upward through the atmosphere. • The air parcel expands as it rises and this expansion and causes the temperature of the air parcel to decrease.
  3. 3. Condensation • As the parcel rises the air is cooler. • Cold air holds less water than hot air, therefore, the water vapor gets closer together, and cloud droplets begin forming. CONDENSATION Water vapor combing to make water droplets
  4. 4. Formation… • This can happen through many different ways – Convection Currents – Lifting – Frontal Activity
  5. 5. Convection Currents
  6. 6. Lifting (help of mountains)
  7. 7. Frontal Activity (Warm & Cold)
  8. 8. • There are many different types of clouds. They are classified as: • High Altitude • Middle Altitude • Low
  9. 9. • HIGH ALTITUDE CLOUDS: • Cirrocumulus – Puffy, patchy look with spaces • Cirrostratus – light gray or white, thin, covers most of the sky. • Cirrus – thin wispy and feathery appearance
  10. 10. • MIDDLE ATLTITUDE CLOUDS: • Altocumulus – puffy, patchy look with spaces • Altostratus – light gray and uniform in appearance. Covers most of the sky.
  11. 11. • LOW ATITUDE CLOUDS: • Cumulus – puffy, looks like cotton balls/popcorn • Stratus – light/dark gray and uniform. Fog! • Stratocumulus – irregular masses, rolling or puffy with spaces. • Nimbostratus – dark gray with precipitation falling from them. Bases are hard to see b/c of rain. • Cumulonimbus – large clouds w/ dark bases and tall billowing towers. Also known as “Thunder Clouds”
