Understanding Atmospheric Equilibrium and Stability: A Comprehensive Guide

Explore the concepts of stable, unstable, and neutral equilibrium in the atmosphere, with a focus on adiabatic cooling and warming processes. Learn about the behavior of unsaturated and saturated air, as well as the effects of subsidence inversion and convective instability on atmospheric stability. Gain insights into how temperature changes affect air stability and discover strategies to make the air more stable or unstable. This guide provides valuable information for understanding atmospheric dynamics and predicting weather patterns accurately.

  1. Stable Equilibrium Unstable

  2. Neutral Equilibrium

  3. ?_________ ? Equilibrium

  4. ? ______ ? Equilibrium

  5. Unsaturated Air Adiabatic cooling Adiabatic warming

  6. Saturated Air (on the way up) Adiabatic cooling 18 oC 18 oC Adiabatic warming 24 oC 28 oC 30 oC 38 oC

  7. Stable Atmosphere Dry air Lifted, unsaturated air at each level is colder and heavier than the air around it. If given the chance the parcel would return to its original position

  8. Stable Atmosphere Moist air

  9. Unstable Atmosphere Dry air

  10. Unstable Atmosphere Moist Air air

  11. Stable Atmosphere Dry air

  12. Unstable Atmosphere Moist air

  13. Making the air more stable Do Both Warm the air above Cool the air below

  14. Making the air more unstable Do Both cool the air above warm the air below

  15. Subsidence Inversion (creating a stable environment through sinking air) +4.6 km = + 46 °C +4.2 km = + 42 °C

  16. More or Less Stable?

  17. Convective instability (creating an unstable environment through rising air)
