Mean Rainfall Patterns for the Three Phases of GATE
(American Meteorological Society, 1979)As a part of the GARP Atlantic Tropical Experiment (GATE), quantitative precipitation measurements were made during the summer of 1974 with four C-band digital radars complemented by shipboard raingages. Isohyetal maps ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part V: Hailstone Embryo Types
(American Meteorological Society, 1979)Hailstones collected within or near the National Hail Research Experiment (NHRE) target area on 23 days of the randomized seeding experiment were sectioned and classified as to embryo type. No significant correlations were ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part VII: Seeding Logistics and Post Hoc Stratification by Seeding Coverage
(American Meteorological Society, 1979)An analysis of the seeding operations during the National Hail Research Experiment 1972?74 randomized seeding program is carried out for the purpose of critiquing the seeding procedures and establishing the actual rates ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part VI: Post Hoc Stratification by Storm Intensity and Type
(American Meteorological Society, 1979)The surface hail and rain data collected during the randomized seeding experiment of the National Hail Research Experiment (NHRE) are stratified according to storm intensity in a search for seeding effects. The problems ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part II: Surface Data Base and Primary Statistical Analysis
(American Meteorological Society, 1979)An extensive statistical analysis is made of the precipitation data collected during the randomized seeding experiment conducted by the National Hail Research Experiment during 1972-74, aimed at testing the feasibility of ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part III: Analysis of Hailstone Size Distributions for Seeding and Yearly Effects
(American Meteorological Society, 1979)The hailstone size (diameter) distributions measured by hailpads during the 1972-74 randomized seeding experiment of the National Hail Research Experiment are analyzed statistically for evidence of seeding effects and ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part I: Design and Conduct of the Experiment
(American Meteorological Society, 1979)The results of a three-year randomized seeding experiment carried out as part of the National Hail Research Experiment are described in a nine-part series. In this first part the design of the statistical experiment is ... -
Criteria for the Detection of Hail Cells
(American Meteorological Society, 1979)One of the Soviet seeding criteria used to detect hail cells at an early stage of development is examined. The radar history of 195 strong convective cells is studied and compared with information of a dense hailpad network ... -
Results of a Randomized Hail Suppression Experiment in Northeast Colorado. Part IV: Analysis of Radar Data for Seeding Effect and Correlation with Hailfall
(American Meteorological Society, 1979)Radar data collected during the seeding experiment of the National Hail Research Experiment are used in a search for possible effects of seeding. Two types of variables, denoted by P and Q, are defined as daily integrals ... -
Heat Island Convergence in St. Louis during Calm Periods
(American Meteorological Society, 1979)From Regional Air Monitoring System (RAMS) tower data recorded in St. Louis during 1976, time series of convergence, heat island intensity and solar radiation are presented for five calm periods each exceeding 12 h. The ... -
A Numerical Simulation of Fog Dissipation Using Passive Burner Lines. Part I: Model Development and Comparison with Observations
(American Meteorological Society, 1979)A two-dimensional model is developed to simulate dissipation of fog using passive burner lines under either cross-wind or no-wind conditions. The vorticity model developed by Murray (1970) forms the basis for the development. ... -
The Importance of Moisture Fluctuations and Wind Shear in Acoustic Backscatter in GATE
(American Meteorological Society, 1979)We explain, using in situ data, some of the mechanisms contributing to acoustic backscatter measured using an active, vertically pointing echosonde (acoustic sounder) mounted aboard ship in the tropical Atlantic. Averaged ... -
A Numerical Simulation of Fog Dissipation Using Passive Burner Lines. Part II: Sensitivity Experiments
(American Meteorological Society, 1979)A two-dimensional model (Tag, 1979) is used to perform sensitivity experiments simulating fog dissipation using passive burner lines under both cross-wind and no-wind conditions. For a cross-wind experiment, heat output ... -
A Comparison of Several Forms of Eddy Viscosity Parameterization in a Two-Dimensional Cloud Model
(American Meteorological Society, 1979)A two-dimensional model is used to test the effects of using several forms of eddy viscosity parameterization to simulate subgrid-scale turbulence. A well-documented observation of a quasi-steady cumulus cloud which formed ... -
A Comparison of Three Methods for Measuring Mixing-Layer Height
(American Meteorological Society, 1979)Temperature profile, lidar and sodar results for determination of mixing-layer heights during October 1977 are compared. While the overall agreement was good, systematic differences do appear, particularly in early morning ... -
In Situ Aircraft Verification of the Quality of Satellite Cloud Winds over Oceanic Regions
(American Meteorological Society, 1979)A 5-year aircraft experiment to verify the quality of satellite cloud winds over oceans using in situ aircraft Inertial Navigation System wind measurements has been completed. The final results show that satellite measured ... -
Relationships among Lead, Iodine, Trace Metals and Ice Nuclei in a Coastal Urban Atmosphere
(American Meteorological Society, 1979)Particulate lead, aluminum, sodium, vanadium, manganese and iodine, vapor phase iodine and ice nuclei were measured simultaneously in Providence, Rhode Island, over a period of one year. Interrelationships found were ... -
The Impact of Waste Heat Release on Climate: Experiments with a General Circulation Model
