  1. Today’s Objective: How Are Clouds And Precipitation Related? Do Now: Describe what condensation and precipitation are

  2. **When air expands, it cools, and when air is compressed, it warms.**

  3. Orographic lifting: occurs when mountains act as barriers to the flow of air, forcing the air to ascend. Air is pushed over the mountain, is cooled and then condenses into a cloud.

  4. Orographic lifting: Leeward Warm & Dry Windward Cool & Wet

  5. Formation of Clouds 1. Form when air rises in the atmosphere and is cooled to the Dew Point Temp. 2. Liquid water condenses around small solid particles (floating dust or salt) called condensation nuclei. 3. Tiny droplets then float in the air.

  6. Cloud Types: Cumulus clouds, fly puffy and whiteSome look like cottonballs, fluffy and light

  7. The Nimbus clouds fly dark and lowWhen you see them, it means rain or snow.

  8. Cirrus clouds are feathery and whiteThey’re made of ice and fly at a great height

  9. Stratus clouds have a layered lookstacking clouds like a book.

  10. Fog is the lowest cloud you can seeMaybe a cloud that got caught in a tree.

  11. FOG • Is a cloud in contact with the ground. • Most types of fog form when the relative humidity reaches 100% at ground-level.

  12. Precipitation: - occurs when cloud droplets or ice crystals grow heavy and fall to the Earth.

  13. Types of Precipitation: Rain: all liquid water. Sleet: ice crystals partly melt while falling. Snow: vapor changes directly into ice crystals. Glaze: rain or sleet freezes when touching the cold ground. Hail: rain drops are blown up by wind freezing into ice pellets.
