S-290 Unit 6: Atmospheric Stability
  1. Explain the relationship between atmospheric pressure, temperature, density, and volume using air parcels.
  2. Describe environmental lapse rate and stability, and the different lapse rates used to determine the stability of the atmosphere.
  3. Differentiate between dry and moist adiabatic rates
  4. Describe the effects of atmospheric stability on wildland fire behavior.
  5. Identify four types of temperature inversions and describe their influence on wildland fire behavior, including the role of the thermal belt.
  6. Name and describe the four lifting processes that can produce thunderstorms.
  7. Describe the elements of a thunderstorm and its three stages of development.
  8. Use visual indicators to determine the stability of the atmosphere.
  9. Describe the four principal cloud groups, and identify the six clouds most often associated with critical wildland fire behavior.
