10. What accompanies horizontal divergence near the earth's surface? What effect is this
likely to have on the thermal stability of this layer?
11. At what time of day and under what meteorological conditions is maximum ground-level
pollution likely to occur at locations several kilometers inland from a shoreline industrial
complex whose pollutants are released primarily from stacks of moderate height (about
40-130 m)?
12. When the regional winds are light, at what time of day and what location might high
ground-level concentrations of pollutants occur from the low-level sources (less than
20 m) of a town in a north-south-oriented valley whose floor slopes down to the north?
Can you answer this question for sources releasing in the range 50-70 m aboveground?
