CHEM 302 Chapter Notes - Chapter 4: Vertical Draft, Tropopause, Molecular Diffusion
Document Summary
Problems: 1 dilution of power plant plumes. Match each power plant plume (1-4) to the corresponding atmospheric lapse rate (a-d, solid lines; the dashed line is the adiabatic lapse rate g ). 70: 2 short questions on atmospheric transport, pollutants emitted in the united states tend to be ventilated by vertical transport in summer and by horizontal transport in winter. Explain this seasonal difference: solar heating of the earth"s surface facilitates not only the upward but also the downward transport of air pollutants. Explain: a monitoring station measures the vertical concentration profiles of a pollutant emitted at a constant and uniform rate at the surface. The profiles measured on two successive days are shown below: z. How would you explain the other profile: a power plant in a city discharges a pollutant continuously from a 200-m tall stack. In a conditionally unstable atmosphere (-dt/dz < g w), is a cloudy air parcel. 71: 3 seasonal motion of the itcz.
