The Livermore Regional Air Quality Model: I. Concept and Development
(American Meteorological Society, 1978)By using the Eulerian form of the mass conservation equation integrated vertically from the surface to the base of the inversion, two regional air quality models (LIRAQ-1 and LIRAQ-2) have been developed for use in the San ... -
The ANL 403 MHz Radiosonde System
(American Meteorological Society, 1978)A new radiosonde system considerably improves the detection of fine temperature structure in the lower atmosphere. Special features of the system include a simple, inexpensive radiosonde which uses a monolithic timer in a ... -
MASCON—A Mass Consistent Atmospheric Flux Model for Regions with Complex Terrain
(American Meteorological Society, 1978)MASCON was developed to provide air pollution models for the San Francisco Bay Area with mass consistent meteorological input data. Measurements of inversion base heights above topography and mean winds within the mixed ... -

A Comparison of Results Using Second-Order Moments with and without Width Correction to Solve the Advection Equation
(American Meteorological Society, 1978)The method of moments is used with and without a width-correction technique to solve the advection of a passive scalar. The method of moments is free of numerical dispersion but suffers from numerical diffusion (damping). ... -
A Technique for Evaluating the Effectiveness of Hurricane Modification Experiments
(American Meteorological Society, 1978)Plans are underway to attempt to reduce the destructive force of hurricanes by artificially modifying their structure by means of cloud seeding. Since the natural variability of meteorological elements observed in hurricanes ... -
An Evaluation of Precipitation Scavenging Rates of Background Aerosol
(American Meteorological Society, 1978)Concentrations of radon daughters in falling rain have been used to derive precipitation scavenging rates of those particles with which radon daughters are associated; presumably these are the particulate component of ... -
Considerations for Pulse-Doppler Radar Observations of Severe Thunderstorms
(American Meteorological Society, 1978)Data show that Doppler shift of storm echoes and the range extent of severe storm systems encompass a span exceeding the unambiguous resolving capability of centimetric radars. Echo coherency which is related to Doppler ... -
Radar Precipitation Maps as Lightning Indicators
(American Meteorological Society, 1978)Radar maps of precipitation at a height of 6 km have been studied for the thunderstorms of one July day. Regions on these maps within which the intensity level exceeds 30 dBZ (corresponding to a rainfall rate of 2.8 mm ... -
Horizontal Scales of Motion in Atmospheric Free Convection Observed during the GATE Experiment
(American Meteorological Society, 1978)An investigation of the dominant horizontal scale of motion in free convection, using data from GATE, principally from the NOAA acoustic sounder, is described. The horizontal scale was seen to vary from two times the depth ... -
Statistical Models of Summer Rainshowers Derived from Fine-Scale Radar Observations
(American Meteorological Society, 1978)This study concerns the statistical modeling of rain cell characteristics based on high-resolution radar measurements of the cell structure. The fine-scale three-dimensional structure of summer rainshowers in the mid-Atlantic ... -
Concerning the Use of Routine Meteorological Data in Estimating Atmospheric Diffusion Parameters
(American Meteorological Society, 1978)By using an integrated form of the Businger-Dyer flux-gradient equations, routine measurements of wind speed and vertical temperature difference in the surface layer are related to low-level atmospheric turbulence and ... -
Plume Rise at Large Distances from a Multiple-Source Region
(American Meteorological Society, 1978)The relation between wind speed, atmospheric stability and plume rise at a distance of 2.5 km from a source region is investigated. The pollution measured in Montreal, Canada, originated from an industrial complex composed ... -
Estimated Effective Chimney Heights Based on Rawinsonde Observations at Selected Sites in the United States
(American Meteorological Society, 1978)The plume rise equations of Briggs (1975) for variable vertical profiles of temperature and wind speed are described and applied for hypothetical short and very tall chimneys at five National Weather Service rawinsonde ... -

Time Series Analysis of Daily Maximum Temperatures on a Mountain Slope
(American Meteorological Society, 1978)Summertime daily maximum temperatures from seven different mountain sites in northern Idaho were modeled using time series analysis and probability distribution analysis. The time series models and probability models were ... -
A Comment on the Size Distribution of the Droplets Found in Cloud Bases
(American Meteorological Society, 1978)Growth histories of droplets are compared and a qualitative argument is given for the generation of the droplet size distribution in the base of a cloud. The distribution is generated by considering only the effects of ... -
High-Frequency Temperature and Humidity Correlation Above a Warm Wet Surface
(American Meteorological Society, 1978)Temperature and humidity fluctuations at frequencies within the inertial subrange are found experimentally to be partially correlated in the surface boundary layer over warm wet surfaces. The spectral correlation coefficient, ... -
The Possibility that Changes in Cloudiness Will Compensate for Changes in Ozone and Lead to Natural Protection Against Ultraviolet Radiation
(American Meteorological Society, 1978)Sunshine duration and total ozone trends from 1963 to 1975 for the United States are compared. It is found that in winter, spring, and summer sunshine variations correlate well with ozone variations. It is concluded that ... -
