      Spittlehouse, D. L.; Black, T. A. (American Meteorological Society, 1979)
      Rates of evapotranspiration from a 14 m high Douglas fir forest on the southwest coast of British Columbia were obtained using the energy balance/Bowen ratio method and an energy balance/eddy correlation method. In the ...
    • An Areal and Temporal Analysis of Precipitation in the Northeastern United States 

      Scott, Cynthia M.; Shulman, Mark D. (American Meteorological Society, 1979)
      Harmonic analysis, an objective method of analyzing precipitation seasonality, is applied to 1941?70 monthly precipitation normals for nearly 200 stations in the northeastern United States. Our analysis presents distribution ...
    • Raindrop Sizes and Related Parameters for GATE 

      Austin, Pauline M.; Geotis, Spiros G. (American Meteorological Society, 1979)
      Several sets of drop size measurements were made on ships and aircraft during GATE. The data were taken primarily as support for the radar measurements and have been analyzed to provide relations between radar reflectivity ...
    • Path-Averaged Measurements of Rain Rate and Raindrop Size Distribution Using a Fast-Response Optical Sensor 

      Wang, Ting-I.; Earnshaw, K. B.; Lawrence, R. S. (American Meteorological Society, 1979)
      Path-averaged terminal velocity distribution of raindrops is determined from the temporal covariance function of signals from two vertically spaced linear optical detectors that respond to raindrop-induced amplitude ...
    • Thunderstorm Intensity as Determined from Satellite Data 

      Adler, Robert F.; Fenn, Douglas D. (American Meteorological Society, 1979)
      Digital infrared data from a geosynchronous satellite (SMS 2) on 6 May 1975 are used to study thunderstorm vertical growth rates and cloud top structure in relation to the occurrence of severe weather (tornadoes, hail and ...
    • A Diagnostic Examination of a Complementary Relationship between Actual and Potential Evapotranspiration 

      LeDrew, Ellsworth F. (American Meteorological Society, 1979)
      Morton (1969, 1975) proposed that the actual and potential evapotranspiration may behave in a complementary fashion about some definable constant as the regional surface dries from an initial saturated condition. He supported ...
    • A Phase-Locked Loop Continuous Wave Sonic Anemometer-Thermometer 

      Larsen, S. E.; Weller, F. W.; Businger, J. A. (American Meteorological Society, 1979)
      A continuous wave sonic anemometer-thermometer has been developed for simultaneous measurements of vertical velocity and temperature. The phase angle fluctuations are detected by means of a monolithic integrated phase-locked ...
    • Some Statistics of Lagrangian and Eulerian Wind Fluctuations 

      Hanna, Steven R. (American Meteorological Society, 1979)
      The linear relationship u?(t + τ) = u?(t)R(τ) + u?(t) is shown to be approximately valid for Lagrangian and Eulerian wind speed observations in the planetary boundary layer, where t represents any time and t + τ is some ...
