2 cards from this section. Quick, good the night before a test.
What is the adiabatic lapse rate?
Think about how temperature changes as air rises.
Define looping in plume behavior.
Remember, vertical movement occurs when the air is unstable.
What happens to a pollutant plume in unstable atmospheric conditions?
Think about the behavior of hot air.
Is fanning associated with high or low dispersion?
Recall the description of fanning conditions.
Given a scenario of urban pollution during summer, where the environmental lapse rate is observed at -4 °C/km, analyze and predict the dispersion shape. Discuss the factors influencing your prediction.
Focus on the relationships between the lapse rates.
Calculate the mixing height when the environmental lapse rate is reported as -6 °C/km and the adiabatic lapse rate is -9.8 °C/km. Describe the implications for pollution transport.
Analyze how the difference in lapse rates affects the mixing height.
