Generation and Sampling of Helium Clouds for Studying Mass Diffusion
(American Meteorological Society, 1972)An experimental technique to study diffusion of helium gas from an instantaneous point source within a neutral turbulent boundary layer is described. Concentrations from a simulated point source, located at a fixed height ... -
Estimating the Extreme-Value 1-Minute Ranifall
(American Meteorological Society, 1972)This paper is concerned with the problem of estimating the probabilities of extreme-value 1-minute rainfalls when series of annual maxima for this duration are unavailable. A relationship between 1- and 5-min values from ... -
Analysis of the Structure of Precipitation Patterns in New England
(American Meteorological Society, 1972)The studies presented here were undertaken to provide a specific and quantitative description of the precipitation patterns in New England storms. Basic data were quantitative radar observations and detailed raingage ... -
Probability Distribution of Vertical Longitudinal Shear Fluctuations
(American Meteorological Society, 1972)In order to properly design aerospace systems (conventional airplanes, V/STOL vehicles, space vehicles, etc.) the engineer must consider the vertical structure of the horizontal wind during the launch and landing phases ... -
Satellite-Observed Southern Hemisphere Cloud Vortices in Relation to Conventional Observations
(American Meteorological Society, 1972)A classification scheme for cloud vortices recorded on hemispheric digital mosaics southward of 20S during a period of some 550 days is used to construct models based on observations of associated atmospheric structure. ... -
Automated Streamline Analysis Utilizing “Optimum Interpolation”
(American Meteorological Society, 1972)A program for automated streamline analysis is described based an ?optimum interpolation? techniques. Streamlines may be directly interpolated from irregularly timed and spaced wind observations. Smoothing of the wind ... -
Empirical Orthogonal Representation of Time Series in the Frequency Domain. Part II: Application to the Study of Tropical Wave Disturbances
(American Meteorological Society, 1972)Rawinsonde data from the western Pacific region for the summer of 1967 are expanded in terms of complex empirical orthogonal functions and the results are compared with those of previous investigations based on the same ... -
Empirical Orthogonal Representation of Time Series in the Frequency Domain. Part I: Theoretical Considerations
(American Meteorological Society, 1972)Difficulties in using conventional cross-spectrum analysis to explore atmospheric wave disturbances have indicated the need for some extension of the usual technique. It is suggested here that the eigenvectors of the ... -

Comments on Corrections to Betasonde Density Data Obtained at High Altitudes
(American Meteorological Society, 1972)tract -
Terminal Fallspeeds of Raindrops
(American Meteorological Society, 1972)For the relationship of terminal fallspeed to size in the raindrop-size range 0.1≤d≤5.8 mm, a two-domain regression scheme is presented. The third-degree regression divided at d= reproduces the basic data from Gunn and ... -
Estimates of Fog Element Length
(American Meteorological Society, 1972)The size of horizontal transmittance discontinuities must be known in order to optimize time and spatial representativeness of automated transmittance measurements. Results of computations using observed parameters are ... -
A Note on the Albedo of Surfaces
(American Meteorological Society, 1972)The albedo of a variety of surfaces was measured for a total of approximately 400 hr with Middleton solari-albedometers whose outputs were recorded by a computer-controlled data acquisition system. The albedo for each ... -
The Effect of Changing, CO2 Concentration on Radiative Heating Rates: Further Comments
(American Meteorological Society, 1972)Changes in radiative heating and cooling rates due to both the near Infrared and 15?bands of CO2 are computed for changes in CO2 concentration from 320 to 600 and 1000 ppmv. An increase in CO2 concentration leads to a ... -
Dobson Ozone Spectrometer Modification
(American Meteorological Society, 1972)Several antiquated electronic design features of the Dobson ozone spectrophotometers have been replaced with revised circuitry, resulting in instruments with improved performance characteristics. -
Wind Tunnel Investigation of Shapes of Balloon Shelters
(American Meteorological Society, 1972)In support of a balloon shelter development program a series of wind tunnel tests were performed. The study concerned the scaling criteria for such a simulation; velocity, turbulence and frequency spectra downwind of four ... -
Cup Anemometer Response to Fluctuating Wind Speeds
(American Meteorological Society, 1972)An investigation is made into cup anemometer response to fluctuating wind speeds. The anemometer overruns under these conditions and the percentage overrun depends on the wind speed, and the frequency and amplitude of the ... -
Climatological Assessment of Urban Effects on Precipitation at St. Louis
(American Meteorological Society, 1972)An investigation was made of urban effects on precipitation in and downwind of St. Louis through use of long-term climatic records within a radius of 50?75 mi of the city. Based upon radar climatological studies, two ... -
Computer Model Determination of Convective Cloud Seeded Growth Using Project Whitetop Data
(American Meteorological Society, 1972)The one-dimensional cumulus dynamics model of Simpson and Wiggert has been applied to a large set of southern plains summer soundings to determine the seeding potential in terms of cloud growth and tower precipitation ...
