These are the types of questions that will be asked. Please answer all of the questions in the document.
The following temperatures and elevations are measured by a weather balloon. The ambient lapse rate is depicted in the diagram below.
Thermometer (oC)
Adiabatic Rate of Adiabatic Lapse (km)
Lapse Rate in the Environment (km)
(5pts) Fill in the dry adiabatic lapse rate values in the table for a parcel of air on the ground (at 0km altitude and 30oC) if you were to raise the parcel until it cooled to 0oC.
(5pts) What is the mixing depth of the atmosphere under these conditions based on this diagram?
(10pts) What is the ventilation coefficient (Vc) if the average wind speed is 2 m/s? Is there a significant risk of pollution?
(10pts) At what heights does the atmosphere remain stable? What altitudes does the atmosphere become unstable? (Hint: compare the dry adiabatic lapse rate to the ambient slopes.)
(Second) (20pts) A campfire generates CO at a rate of 20g/s on a clear night with winds of 2m/s. Assume the fire’s effective stack height is 6 meters. 400m immediately downwind, what would you estimate the CO ground-level concentration to be?
3.)(25pts) On a clear fall day, a line of burning agricultural trash generates 0.3 g/m*s of PM10, with the wind blowing at 3 m/s perpendicular to the burning line. What do you think the ground-level PM10 concentration will be 900 meters downwind?
(No. 4) (25pts) Consider a metropolis with a 100,000m airshed on each side and a mixing depth of 1,200m. Estimate the steady-state SO2 concentration in the airshed assuming clean air enters at a speed of 4 m/s and SO2 is emitted at a rate of 20 kg/s within the airshed. Assume that SO2 is low. (Hint: use the conservation of mass concepts to set this up like our box models from lesson 2.) Include a schematic of the model if possible.
