QUESTIONS
1
1. In a situation under stable conditions with a wind speed of 4 m s" and a a = 0.12 radians,
the wind is blowing directly toward a receptor 1 km from the source. How much must
the wind shift, in degrees, to reduce the concentration to 10% of its previous value? (At
2.15(r from the peak, the Gaussian distribution is 0.1 of the value at the peak.)
2. If the variation in wind speed with height is well approximated with a power law wind
profile having an exponent equal to 0.15, how much stronger is the wind at 100 m above
ground than at 10 m?
