Laser Sensing of Cloud Composition: A Backscattered Depolarization Technique
(American Meteorological Society, 1974)Theoretical analyses reveal that the backscattered radiation from spherical water droplets retains the polarization of the incident energy, whereas radiation backscattered from non-spherical ice crystals is partially ... -
Concurrent FM-CW Radar and Lidar Observations of the Boundary Layer
(American Meteorological Society, 1974)Boundary layer probing by multiple remote sensors can greatly improve the understanding of processes in this complex region. For this purpose one needs to know the unique information each individual sensor can provide. Two ... -
Study of Divergence in the Boundary Layer Using Optical Propagation Techniques
(American Meteorological Society, 1974)A wind-measuring system using three separate optical systems, each consisting of a 3 mW He-Ne 1aser and two photodiode receivers, forming an equilateral triangle 300 m on a side, has successfully measured the divergence ... -
Statistical Properties of Vertical Shear of Lateral Velocity
(American Meteorological Society, 1974)The statistical properties of two-point differences, ?v?, along the vertical of the lateral component of turbulence (horizontal component perpendicular to mean wind vector) in the first 150 m of the unstable atmospheric ... -
Lysimetric Calibration of the Bowen Ratio-Energy Balance Method for Evapotranspiration Estimation in the Central Great Plains
(American Meteorological Society, 1974)Most reports show good agreement between evapotranspiration (ET) rates estimated by the Bowen Ratio-Energy Balance (BREB) method and rates measured with lysimeters, although underestimation by the BREB model has occasionally ... -
Spectral Representation of Horizontal Wind in Numerical Models of the Atmosphere
(American Meteorological Society, 1974)Use of the primitive equations in spectral models of the atmosphere raises certain questions about the representation of the horizontal components of velocity therein. A barotropic model is constructed and integrated using ... -
Prediction of Precipitation Probability Based on 500-Mb Flow Types
(American Meteorological Society, 1974)Regression techniques are applied on stratified and non-stratified data to obtain prediction equations for the probability of precipitation over the western continental United States. The stratification is based on 500-mb ... -
Synoptic Climatology of 500-mb Winter Flow Types
(American Meteorological Society, 1974)An objective correlation method is used to obtain seven typical 500-mb winter flow Patterns Over the western United States and eastern Pacific Ocean. The frequency of occurrence of each type is presented. The atmospheric ... -
Comments on “A General Description of the Hail Problem in the Po Valley of Northern Italy”

Apparent Periodicities in Rainfall at Fortaleza, Ceará, Brazil
(American Meteorological Society, 1974)Fortaleza's rainfall contains long-term variations that from autocorrelation analysis appear to be of periodic or quasi-periodic form. -
Effect of Moisture on the Hydrostatic Pressure
(American Meteorological Society, 1974)This Note describes a method of deriving a modified form of the hydrostatic equation by making allowance for the presence of moisture in an atmospheric column. -

The Limitations of Wind Measurement Accuracy for Balloon Systems
(American Meteorological Society, 1974)The error in horizontal wind field measurements as computed from the trajectory of balloons with linear and quadratic rise rates (as functions of altitude) has been derived. Balloon trajectories through light, moderate and ... -
Analysis of the Research Flight Facility Gust Probe System
(American Meteorological Society, 1974)Analysis of the frequency response of the input parameters of a gust probe system, which measures the turbulent flow of air, is presented. The results show that the system is very sensitive to noise created by aircraft ... -
Response Characteristics of Two Automatic Ice Particle Counters
(American Meteorological Society, 1974)Two automatic ice particle counters, one operating in the visible and the other in the infrared spectrum, were tested. The operation of both units is based upon the cross-polarization technique for discriminating between ... -
The Measurement of Charge and Size of Raindrops: Part II. Results and Analysis at Ground Level
(American Meteorological Society, 1974)Measurements of the size and charge on precipitation particles obtained using the apparatus described in Part I are given. Size data are found most frequencly to fit a log-normal distribution, and charge data a normal ... -
The Measurement of Charge and Size of Raindrops: Part I. The Disdrometer
(American Meteorological Society, 1974)An apparatus is described which enables reliable measurement of precipitation charge and size to be made. Design criteria are thoroughly treated and general solutions are provided to all aspects of the problem. The theories ... -
Equations for Calculating the Terminal Velocities of Water Drops
(American Meteorological Society, 1974)The experimental data of Gunn and Kinzer, Beard and Pruppacher, and Davies are used to curve-fit a polynomial for Re in terms of CdRe2. The resulting equations predict very accurately all known experimental data for drop ... -
Observations of Aerosols over Southern California Coastal Waters
(American Meteorological Society, 1974)To characterize the background aerosol in air off the California coast, observations of suspended particles were made in the summer and fall of 1970 on San Nicolas Island (SNI), located about 130 km west-south-west of Los ...
