Bulk Parameterization of the Snow Field in a Cloud Model
(American Meteorological Society, 1983)A two-dimensional, time-dependent cloud model has been used to simulate a moderate intensity thunderstorm for the High Plains region. Six forms of water substance (water vapor, cloud water, cloud ice, rain, snow and hail, ... -
A Surface-Corrected Gaussian Model for Elevated Sources
(American Meteorological Society, 1983)A Gaussian model for continuous elevated sources is developed which uses a continuous distribution of ground-level sources to replace the use of the image source. For the case of Fickian diffusion with uniform wind, this ... -
The Relationship Between the Surface Wind Field and Convective Precipitation over the St. Louis Area
(American Meteorological Society, 1983)Rainfall, wind and temperature data at the surface for a mesoscale area surrounding St. Louis, Missouri for seven summer days in 1975 were used to determine qualitative and quantitative relationships between divergence, ... -
Visual Cloud Histories Related to First Radar Echo Formation in Northeast Colorado Cumulus
(American Meteorological Society, 1983)Using quantitative analysis of time-lapse motion pictures from aircraft and a sensitive meteorological radar, the cloud top history is related to the early radar echo development in 12 vigorous, summer, convective cloud ... -
Specification of Monthly Precipitation in the Western United States from Monthly Mean Circulation
(American Meteorological Society, 1983)The ability to specify monthly precipitation at 36 stations in Washington, Oregon and California by various indices of monthly mean circulation has been investigated. Most of the circulation indices were derived from ... -
Hailstone Growth Trajectories in the Dynamic Evolution of a Moderate Hailstorm
(American Meteorological Society, 1983)For the purpose of studying the growth environment of hailstones in a moderate storm, more than 200 hailstones, collected at several points along the storm path, were investigated by crystallographic and isotopic analysis. ... -
Improvements in Cloud Photogrammetry Using Airborne, Side-Looking, Time-Lapse Cameras
(American Meteorological Society, 1983)An airborne photographic system, in which the cameras are coupled with an inertial navigation system, was developed and used in a 1978 convective cloud study, Photogrammetric analysis from such a system is enhanced: ... -
Diurnal Radiance Patterns of Finite and Semi-Infinite Clouds in Observations of Cloud Fields
(American Meteorological Society, 1983)One of the important radiative effects of cloud Shape is to modify diurnal radiance patterns observed from satellites. Theory predicts a diurnal radiance pattern nearly symmetric about local noon for both semi-infinite and ... -
Heavy Thunderstorms Observed Over Land by the Nimbus 7 Scanning Multichannel Microwave Radiometer
(American Meteorological Society, 1983)In an examination of microwave data from the Nimbus 7 satellite, brightness temperatures were found that were much lower than those expected for the radiation emanating from rain-producing clouds. Every case of very cold ... -
Some Singularities and Irregularities in the Seasonal Progression of the 700 mb Height Field
(American Meteorological Society, 1983)A climatological investigation of singularities in the seasonal progression of 5-day means of 700 mb height was undertaken for the region 30?90°N, from 160°E eastward to 0°, for the period 1947?76. A harmonic analysis was ... -
Design and Verification of a Cloud Field Optical Simulator
(American Meteorological Society, 1983)A concept and an apparatus designed to investigate the reflected and transmitted distributions of light from optically thick clouds is presented. The Cloud Field Optical Simulator (CFOS) is a laboratory device which utilizes ... -
Means and Standard Deviations of Horizontal Wind Components
(American Meteorological Society, 1983)An algorithm is presented that computes a measure of horizontal wind dispersion. The algorithm features a compact, machine economic structure that removes wind direction scale discontinuities. By requiring only one pass ... -
Instrumental Effects on the Sunshine Record
(American Meteorological Society, 1983)No abstract available -
Meteorological Tracer Techniques for Parameterizing Atmospheric Dispersion
(American Meteorological Society, 1983)Although tracer materials have been used in atmospheric dispersion studies for decades, basic information about meteorological tracer techniques is scattered among a number of different sources. This paper attempts to pull ... -
The Boulder Atmospheric Observatory
(American Meteorological Society, 1983)The Boulder Atmospheric Observatory (BAO) is a unique research facility for studying the planetary boundary layer and for testing and calibrating atmospheric sensors. The facility includes a 300 m tower instrumented with ... -
Design and Development of a Radar Control Program for the NOAA/WPL Pulse-Doppler Radars
(American Meteorological Society, 1983)Development of a computer program to control and acquire data with meteorological research radars is described. The performance goals for the program are enumerated, and the implementation techniques to achieve these goals ... -
Potential for a Lidar-Based, Portable, 1 km Meteorological Tower
(American Meteorological Society, 1983)Lidar measurements of wind, temperature and water vapor, using a variety of techniques that rely on the detection and analysis of laser light backscattered from the atmosphere, allow data to be obtained that are similar ... -
Surface Meteorological Observations in Severe Thunderstorms. Part I: Design Details of TOTO
(American Meteorological Society, 1983)The TOTO (Totable Tornado Observatory) device was designed as a prototype meteorological measuring instrument for use by severe storm intercept teams. Portions of the instrument evolved from our work in producing ?hardened? ... -
Surface Meteorological Observations in Severe Thunderstorms. Part II: Field Experiments with TOTO
(American Meteorological Society, 1983)The TOTO (Totable Tornado Observatory) device was field tested in the Southern Plains by a severe-storm intercept team from the University of Oklahoma from late May through early June 1981. The results from two intercept ... -
An Analysis and Comparison of Five Water Droplet Measuring Instruments
