Explore atmospheric dynamics in this 45-minute lecture from Yale University's course on The Atmosphere, the Ocean and Environmental Change. Delve into concepts like the lapse rate, atmospheric stability, and temperature inversions. Understand how these factors influence air movement and pollutant trapping in the boundary layer. Examine the diurnal cycle of the adiabatic lapse rate and its effects. Investigate elevated inversions and their impact on pollution. Learn about moisture in the atmosphere and various air saturation processes. This comprehensive lecture covers essential topics in atmospheric science, providing a solid foundation for understanding environmental changes.
