Unit 6

Upon completion of this unit, students will be able to:

1. Describe the relationship among atmospheric pressure, temperature, density, and volume.

2. Describe temperature lapse rate and stability, and the different lapse rates used to determine the stability of the atmosphere.

3. Describe the effects of atmospheric stability on wildland fire behavior.

4. Name four types of temperature inversions and describe their influence on wildland fire behavior, including the thermal belt.

5. Name and describe the four lifting processes that can produce thunderstorms.

6. Describe the elements of a thunderstorm and its three stages of development.

7. Use visual indicators to describe the stability of the atmosphere.

8. Describe the four principle cloud groups, and identify the six clouds most often associated with critical wildland fire behavior.
