1. Aim: How is precipitation related to relative humidity? Topic: Unit 6 Meteorology Main Idea: Moisture

3. 1) Define absolute humidity? This is the exact amount of water vapor in the air.

4. 2) Define relative humidity? This is the comparison between capacity (how much it can hold) and absolute humidity. It is how full the air is.

5. 3) a) Label the capacity and absolute humidity for the following diagram:

6. 3) b) What is the relative humidity? 50 mL/ 100 mL X 100 0.5 X 100 50% relative humidity

7. 4a) Absolute Humidity The higher the absolute humidity, the higher the relative humidity.

8. 4b) Capacity of the air The greater the capacity, the lower the relative humidity.

9. How does temperature affect capacity?

10. 4c) Temperature If the temperature is high the air can hold more water so it is not as full= lower relative humidity.

12. 4d) Dewpoint Temperature Direct relationship. If the air is full the molecules are so close together that a cloud can form at warm (high) temperatures.

13. Changing Air Temperature

14. Changing Absolute Humidity

15. Summary: Graph the three relationships

16. Changing Air Temperature

17. Which of these two station models represent the current weather in Elmont, NY? Give two reasons. Diva Dollar Question: If it is foggy outside and there is dew everywhere, if the sun comes out why doesn’t it rain? (Use all terms we learned yesterday)
