A Method of Measuring Drop Size Distributions in Laboratory Clouds
(American Meteorological Society, 1972)A method of measuring drop size distribution in clouds, especially adapted for wind tunnels and other cloud chambers in which the cloud is carried in an air stream, is presented. It consists of photographing the cloud ... -
A Case Study of Persistent, Intense, Cleat Air Turbulence in an Upper Level Frontal Zone
(American Meteorological Society, 1972)Widespread and persistent clear air turbulence (CAT) occurred over the Eastern Seaboard of the United States between New York and South Carolina on 18 March 1969. The major synoptic features and a qualitative discussion ... -
Calibration Techniques and Testing of Hygrometers for Horizontal Soundings of the Troposphere and Lower Stratosphere
(American Meteorological Society, 1972)The measurement of the water vapor content of the atmosphere from a constant level balloon imposes new requirements, involving very long term stability for several months of flight, and light weight. In the first plan, a ... -
Application of Computed Global Radiation for Areas of High Relief
(American Meteorological Society, 1972)The variation over uneven terrain of the daily total of incident shortwave (global) radiation under cloudless conditions may be estimated by existing methods for calculating direct and diffuse solar radiation on a slope. ... -
The Angular Transmittance Properties of Clouds
(American Meteorological Society, 1972)A series of experimental measurements of the visible light angular transmittance profiles of clouds is described. The results for single-layer overcast clouds were found to correlate well with standard hemispheric and ... -
Areal Coverage of Precipitation in Northwestern Utah
(American Meteorological Society, 1972)Areal coverage of precipitation over a subsynoptic-scale and a mesoscale network of stations in north-western Utah for the four seasons is discussed. As would he expected, 100% areal coverage is rare in summer, but, ... -
Comparative Liquid Water Content Measurements of Conventional Instruments with an Optical Array Spectrometer
(American Meteorological Society, 1972)A comparison study is made of liquid water content measurements using conventional devices with those integrated from optically measured drop size distributions. In clouds of low to medium droplet size (<30 ? diameter) the ... -
Measurement of Snowfall by Radar
(American Meteorological Society, 1972)Using a CPS-9 radar (wavelength 3.2 cm, beamwidth 1°) in dry snow, radar returns from a layer at an average height of 5000 ft were converted to snowfall rates (taking Z?R2.0) and summed over 36 hr to obtain a map of snowfall ... -
Another “Time Lag” in the Activation of Atmospheric Ice Nuclei
(American Meteorological Society, 1972)If most atmospheric ice nuclei activate by contacting or immersing themselves inside a water droplet, then ice nucleus cloud chambers may seriously underestimate the concentration of these particles. Ice nuclei diffuse ... -
Determination of Aerosol Height Distributions by Lidar
(American Meteorological Society, 1972)A new analytic solution to the lidar equation is presented, which realistically considers the scattering properties of the aerosols and the molecular atmosphere individually. With this solution, it is shown, in turbid ... -
Aerodynamic Properties of Spherical Balloon Wind Sensors
(American Meteorological Society, 1972)A first-order theory of the fluctuating lift and drag coefficients associated with the aerodynamically induced motions of rising and falling spherical wind sensors is developed. The equations of motion of a sensor are ... -
Three-Dimensional Air Trajectories Determined from Tetroon Flights in the Planetary Boundary Layer of the Los Angeles Basin
(American Meteorological Society, 1972)Between 9 September and 2 October 1969, 105 constant-volume balloons (tetroons) were released from various sites in the Los Angeles Basin for the purpose of obtaining three-dimensional air trajectories in the planetary ... -
The Measurement of Turbulence in a City Environment
(American Meteorological Society, 1972)The increasing requirement for data about turbulence in a city environment, particularly in relation to building design and the imminent operation of aircraft from this environment, has prompted the measurement of the ... -
Moisture and Temperature Limits of the Equilibrium Evapotranspiration Model
(American Meteorological Society, 1972)Energy balance measurements of evapotranspiration from a developing corn crop are compared with daily equilibrium evapotranspiration estimates to examine the accuracy of the model and the environmental conditions under ... -
Minimum-Time Routing as an N-Stage Decision Process
(American Meteorological Society, 1972)In this paper the problem of determining minimum-time ship routes is expressed as a discrete decision process in stochastic conditions, and is solved by dynamic programming. Some models of such processes are considered. ... -
Objective Analysis of Sea-Level Winds and Pressures Derived from Simulated Observations of a Satellite Radar-Radiometer and Actual Conventional Data
(American Meteorological Society, 1972)A computer-based procedure is developed that combines a field of simulated satellite-derived wind speeds with a limited amount of conventional surface data so as to recover the surface pressure field and the vector wind ... -
An Improved Automatic Cloud Condensation Nucleus Counter
(American Meteorological Society, 1972)The original automatic cloud condensation nucleus counter developed by Radke and Hobbs has been improved by reducing the size and weight of the instrument and increasing the sampling rate. In comparison tests with four ... -
