3 cards from this section. Quick, good the night before a test.
What is the adiabatic lapse rate?
Think about how temperature changes with height.
Define mixing height.
Consider where stabilization occurs for pollutant dispersion.
What is the dry adiabatic lapse rate?
Remember the rule of thumb for temperature decrease with altitude.
True or False: The mixing height is the highest point where pollutants disperse effectively.
Think of mixing height as the effective boundary for dispersion.
A pollutant source emits gases at 10 meters height. If the surrounding atmospheric lapse rate is -0.006 °C/m, calculate the mixing height and discuss the implications for dispersion.
Recall how the mixing height is defined when lapse rates intersect.
Discuss how changing environmental conditions (temperature inversion) might alter expected plume behavior for a factory emitting pollutants on a warm day.
Visualize the inversions as a lid restricting upward air movement.
