      Chung, Y-S. (American Meteorological Society, 1977)
      Photochemical air pollution was studied in the lower Great Lakes region of southern Ontario, Canada, using O3 data for 1973?76 inclusive. High O3 concentrations in the boundary layer are correlated primarily with the several ...
    • Ozone Depletion by Chlorofluoromethanes? Yet Another Look 

      Parry, H. Dean (American Meteorological Society, 1977)
      A number of predictions of stratospheric ozone depletion caused by release of chlorofluoromethanes (Freons 11 and 12) into the atmosphere are described and the wide variation of predicted depletion noted. By using techniques ...
    • Preliminary Tests of a Cumulus Cloud Seeding Technique 

      Isaac, G. A.; Schemenauer, R. S.; Crozier, C. L.; Chisholm, A. J.; MacPherson, J. I.; Bobbitt, N. R.; MacHattie, L. B. (American Meteorological Society, 1977)
      A cloud seeding technique is proposed which has the objective of stimulating rainfall from cumulus clouds drifting over forest fires. Preliminary tests of the ice crystal production capability of the cloud seeding technique ...
    • A Comparison of Oceanic Precipitation as Measured by Gage and Assessed from Weather Reports 

      Reed, R. K.; Elliott, W. P. (American Meteorological Society, 1977)
      The problems of using raingages on ships are discussed, and methods of estimating rainfall from weather reports at sea are reviewed, with emphasis on discussion of efforts to verify the assessments derived by Tucker (1961). ...
    • Thermal Plumes Detected by an Acoustic Echo Sounder 

      Nater, Werner; Richner, Hans (American Meteorological Society, 1977)
      As noted elsewhere, in temperature profiles obtained by a tethered balloon, thermal plumes can be distinguished from true stratification by the simultaneous operation of an acoustic echo sounder. Rising thermals observed ...
    • An Analysis of a Possible Crop Response to Hail Suppression Seeding: The Nelspruit Hail Suppression Project 

      Mather, Graeme K. (American Meteorological Society, 1977)
      A commercial hail suppression program has been in operation at Nelspruit, South Africa (25°S, 31°E) since December 1971. The seeding technique employed has been the ?on-top? method, which consists of dropping silver iodide ...
    • An Improved Method for Determining Measurement System Noise Spectra 

      Goerss, James S. (American Meteorological Society, 1977)
      A simultaneous equations solution technique is developed to estimate the noise variance density spectra of three or more independent measurement systems observing the same input. Using dew-point data collected during a ...
