Lecture 14. Meteorological considerations on transport and dispersion of air pollutants Lesson
Key issues:
- Affected: winds & temperatures profiles, cloud, humidity
- Large‐scale system: high & low pressure
- Small‐scale system: temperatures, moisture
- Forces: acting on air, combination to form winds
- Winds: global, regional, and local circulations
- Effects on air pollution: stability, mixing, build‐up, clean‐out
- Effects on local air pollution: heating, topography, turbulence
- Specific issues of urban heat island, street canyon, breeze cells
