Regional Climatic Effects of Large-Scale Thermal Pollution: Simulation Studies with the NCAR General Circulation Model
(American Meteorological Society, 1979)January and July experiments were performed with the NCAR general circulation model (GCM) to assess the potential climatic impact of the thermal energy released from a projected United States cast coast megalopolis circa ... -
Estimating the Joint Probability of a Weather Event at Two Locations
(American Meteorological Society, 1979)A total of 511 056 hourly observations of precipitation, sky cover, ceiling, visibility, wind speed and temperature, taken over a 13-year period at nine locations, were processed to obtain unconditional and two-location ... -

Melting of a Prairie Snowpack
(American Meteorological Society, 1978)An energy budget approach is used to study the melt of a prairie snowpack. Air temperature, humidity and wind speed are measured at seven levels in the first 2 m above the snow surface. Evaporation and melt are measured ... -
Lake/Land Breeze Circulations on the Western Shore of Lake Michigan
(American Meteorological Society, 1978)A classic lake breeze circulation cell that formed on the western shore of Lake Michigan on 4 September 1974 is studied in great detail. Wind measurements are made with surface anemometers and serial pibals, with air ... -
Relationships of Equivalent Reflectivity Factor to the Vertical Fluxes of Mass and Kinetic Energy of Hail
(American Meteorological Society, 1978)A derivation is given of the relationships of the equivalent reflectivity factor to the vertical fluxes of mass and kinetic energy of hail. It is assumed that the hail is distributed with respect to size according to a ... -
A Hot-Wire Liquid Water Device Having Fully Calculable Response Characteristics
(American Meteorological Society, 1978)A liquid water sensor consisting of a thin copper wire wound on a hollow 1.5 mm diameter cylinder is described. Slave coils on either side of the master sensing coil reduce axial heat losses to an acceptable level, and ... -
Equilibrium and Actual Evapotranspiration from a Very Dry Vegetated Surface
(American Meteorological Society, 1978)Energy balance measurements of evapotranspiration from very dry seeded rangeland grass (Agropyron desertorum) near Kamloops, British Columbia, are compared with daily equilibrium evapotranspiration estimates. The equilibrium ... -
Wind Power Potential in the Pacific Northwest
(American Meteorological Society, 1978)The Pacific Northwest is endowed with substantial resources of both hydro energy and wind energy for electrical power generation. The combination of these energy sources into an integrated and optimized system has the ... -
Comparison of Satellite-Deduced Cloud Heights with Indications from Radiosonde and Ground-Based Laser Measurements
(American Meteorological Society, 1978)Cloud altitudes specified from the Infrared Temperature Profile Radiometer on the Nimbus 5 satellite are compared with simultaneous observations by radiosonde and ground-based ranging measurements conducted with the lidar ... -
Vertical Profiles of Condensation Nuclei
(American Meteorological Society, 1978)Condensation nuclei measurements using a low supersaturation (?10%) thermal gradient diffusion cloud chamber (TGDCC) and a high supersaturation (?200%) expansion type instrument were compared on a series of three balloon ... -
Generalized Criteria for Seeding Winter Orographic Clouds
(American Meteorological Society, 1978)An a posteriori analysis was conducted utilizing precipitation, rawinsonde and seeding generator data from seven randomized winter cloud-seeding research projects conducted in orographic settings in the Rocky Mountain West ... -

A Model of Hygroscopic Seeding in Cumulus Clouds
(American Meteorological Society, 1978)A systematic modeling exploration has been conducted to map the growth and trajectory of hygroscopically initiated precipitation particles. The model used is a one-dimensional, steady-state, condensation-coalescence model ... -
Experimental Evaluation of Ground-Based Microwave Radiometric Sensing of Atmospheric Temperature and Water Vapor Profiles
(American Meteorological Society, 1978)Profiles of atmospheric temperature and water vapor derived from ground-based microwave radiometric measurements are compared with concurrent rawinsonde profiles including both clear and cloudy cases. Accuracies of the ... -
Night Versus Day Cloud Seeding in Langmuir's Periodic Experiment
(American Meteorological Society, 1978)During the last ten 28-day cycles of Langmuir's periodic seeding experiment, beginning 15 October 1950, silver iodide smoke generators were operated one day each week from 1600 to 2400 LT on odd-numbered cycles and from ... -
The Evaluation of Two Years of Real-Time Operation of a Short-Term Precipitation Forecasting Procedure (SHARP)
(American Meteorological Society, 1978)Digital weather radar data have been used with a simple pattern recognition procedure to automatically generate precipitation forecasts in the zero to three hours range. Such a technique has been in real time operation for ... -
Seasonal and Regional Variation in the Correlation of Thunderstorm Days with Tornado Frequency
(American Meteorological Society, 1978)The goal of this study was to determine the degree of correlation between monthly values of thunderstorm days and tornado occurrences in the eastern United States and to determine the geographic and seasonal patterns of ... -
Satellite-Derived Cumulus Cloud Statistics for Western Kansas
(American Meteorological Society, 1978)Increasing world population, decreasing grain reserves and current farm total income levels have aroused interest in new methods that may lead to increased crop production across the Great Plains. Precipitation modification ...
