On the Use of Power Laws for Estimates of Wind Power Potential
(American Meteorological Society, 1978)The evaluation of wind power potential at a proposed aerogenerator site by extrapolation from measured winds at a reference level is investigated. It is shown that the total mean wind power density is not particularly ... -
Comments on “A General Gaussian Diffusion-Deposition Model for Elevated Point Sources”
(American Meteorological Society, 1978)A comparison is made of the Gaussian diffusion-deposition models of Chamberlain (1953) and Overcamp (1976) with the exact solution of Horst (1977). Overcamp's model is found to be a useful improvement over Chamberlain's ... -
A Note on Vertical Extrapolation Formulas for Weibull Velocity Distribution Parameters
(American Meteorological Society, 1978)The adequacy of a vertical extrapolation scheme for Weibull wind speed distribution parameters proposed by Justus and Mikhail is examined. While useful for ensemble averages, the technique can lead to significant errors ... -
Total Ozone Trend Significance from Space and Time Variability of Daily Dobson Data
(American Meteorological Society, 1978)Assessing the significance of apparent total ozone trends is equivalent to assessing the standard error of the means. Standard errors of time (area) averages depend on the temporal (spatial) variability and correlation of ... -
Cloud Effects on Insolation over the Tropical Pacific Ocean
(American Meteorological Society, 1978)Recent oceanic data and measurements at Johnston Island were used to examine insolation over the tropical Pacific by comparison with empirical formulas which are reliable for mid-latitudes. In the eastern Pacific the ... -
The Effect of Markovian and Discrete-Climate Assumptions on the Performance Analysis of Solar Heating Systems
(American Meteorological Society, 1978)Analysis of the performance of a solar heating system is considered by means of a first-order Markov chain model for climatic and thermal-balance conditions. Computational limitations require extremely restrictive modeling ... -
A Comparison between a Steady-State Downdraft Model and Observations Behind Squall Lines
(American Meteorological Society, 1978)A simple parcel model has been used to examine the possibility that observed profiles of ?e following the passage of a squall line are produced by air originating in middle-level clouds and descending in steady rain. The ... -
Comments on “An Approximating Polynomial for the Computation of Saturation Vapor Pressure”
(American Meteorological Society, 1978)Measures to qualify the values of formulas are described. These measures are then used to emphasize the distinction between computation or instrumentation error and environmental variation with particular application to ... -

Interannual Cloud-Cover Variations in the Contiguous United States
(American Meteorological Society, 1978)Using data from sunshine recorders in the contiguous United States, the mean interannual cloud-cover variations at 103 locations are calculated. A typical location has a mean absolute year-to-year variation in cloud cover ... -
Comparison of Observations of Sea Surface Temperatures at Ocean Station P and NOAA Buoy Stations and Those Made by Merchant Ships Traveling in Their Vicinities, in the Northeast Pacific Ocean
(American Meteorological Society, 1978)An analysis of the 6 h observations of sea surface temperatures made at Station P and the eight NOAA buoy stations in the northeast Pacific Ocean indicates that the buoys appear to be providing data that are as reliable ... -
An Application of Rank-Order Statistics to the Study of Hurricane Variability
(American Meteorological Society, 1978)A method is presented for quantifying the temporal variability found in hurricanes. The method is based upon several well-known nonparametric tests that use ranking techniques; among these are tests devised by Kendall, ... -
Variability of Hailstorms on the South African Plateau
(American Meteorological Society, 1978)Detailed climatological studies of hailstorms on the South African plateau have been made using a dense network of voluntary observers. Hailstone structures have been investigated and, since 1971, radar observations have ... -
Methods for Estimating Wind Speed Frequency Distributions
(American Meteorological Society, 1978)The Weibull function is discussed for representation of the wind speed frequency distribution. Methods are presented for estimating the two Weibull parameters (scale factor c and shape factor k) from simple wind statistics. ... -
Measurements of the Energy Fluxes Involved in the Energy Budget of a Snow Cover
(American Meteorological Society, 1978)Measurements of the various energy components involved in an energy balance of a snow cover were made at the Elora Research Station, University of Guelph during the winter of 1976. A pressure sphere anemometer and a sonic ... -
A Mass-Consistent Model for Wind Fields over Complex Terrain
(American Meteorological Society, 1978)An adjustment model was developed to provide a pollutant transport model with input wind fields that are mass-consistent, three-dimensional, and also representative of the available meteorological measurements. Interpolated ... -
Turbulent Exchange Coefficients for Sensible Heat and Water Vapor under Advective Conditions
(American Meteorological Society, 1978)Results are presented of micrometeorological measurements made over alfalfa and soybeans under conditions of sensible heat advection at Mead, Neb. The sensible heat advection phenomenon reported here is of a regional rather ... -
The Livermore Regional Air Quality Model: II. Verification and Sample Application in the San Francisco Bay Area
(American Meteorological Society, 1978)Topographic, meteorological, source emission and atmospheric pollutant concentration data have been assembled for use in verifying the LIRAQ-1 and LIRAQ-2 regional air quality models in the San Francisco Bay Area. These ... -
ADPIC—A Three-Dimensional Particle-in-Cell Model for the Dispersal of Atmospheric Pollutants and its Comparison to Regional Tracer Studies
(American Meteorological Society, 1978)A hybrid Lagrangian-Eulerian atmospheric transport-diffusion model was developed to calculate the three-dimensional distribution of atmospheric pollutants in transient-region flow fields. This Atmospheric Diffusion ... -
