Objective Cross-Section Analyses by Hermite Polynomial Interpolation on Isentropic Surfaces
(American Meteorological Society, 1973)An objective cross-section analysis scheme based upon Hermite Polynomial interpolation on surfaces of constant potential temperature is shown to define frontal-scale horizontal and vertical gradients of potential temperature ... -
Numerical Forecasting Experiments Based on the Conservation of Potential Vorticity on Isentropic Surfaces
(American Meteorological Society, 1973)In a few selected cases of explosive cyclogenesis, a ?coarse-mesh? nine-level isentropic prediction model conserving potential geostrophic vorticity is shown to yield dependable 36-hr forecasts of developing cyclones. ... -

An Objective Method of Preparing Cloud Cover Forecasts
(American Meteorological Society, 1973)The numerical 6-hourly output from the six-layer NMC PE model is used to predict the average daytime cloudiness in the spring for Boston. The variables chosen as predictors are the PE model predictions of the mean surface ... -
Corrections for Response Errors in a Three-Component Propeller Anemometer
(American Meteorological Society, 1973)Methods of eliminating or reducing three types of errors found in the Gill UVW anemometer have been investigated by utilizing field experiments comparing this sensor with a three-component sonic anemometer. The non-cosine ... -
On Rainfall and Space Diversity for Millimeter-Wave Earth-Satellite Communications Systems
(American Meteorological Society, 1973)Space diversity, i.e., the use of several widely spaced terminals, is examined as a means of reducing the probability of simultaneous rainfall in millimeter-wave earth-satellite communications systems. The concept of space ... -
A New Lidar for Meteorological Application
(American Meteorological Society, 1973)A new lidar has been demonstrated to be potentially useful as a meteorological tool. This lidar is the result of applying a new technology, gallium-arsenide fiber coupling. By coupling optical fibers to each of an array ... -
Pulsed-Doppler Velocity Isotach Displays of Storm Winds in Real Time
(American Meteorological Society, 1973)First results derived from an NSSL effort to develop a real-time Plan Position Indicator (PPI) display of Doppler isotachs are described. The mean Doppler velocity is estimated for multiple range locations by measuring the ... -
Wind Gradients and Variance of Doppler Spectra in Showers Viewed Horizontally
(American Meteorological Society, 1973)An X-band pulsed-Doppler radar having its beam fixed at an elevation angle of 3°, has supplied new data on radial velocity spectra in two showers. It was found that the mean Doppler velocity, variance of the Doppler spectrum, ... -
The Loss of Information Due to Finite Sample Volume in Radar-Measured Reflectivity
(American Meteorological Society, 1973)The decrease of the mean square and the variance of reflectivity due to radar beam smoothing and post-detection integration are studied in terms of the autocorrelation function of the field of reflectivity. An exponential ... -
The Distribution of Silver in Precipitation from Two Seeded Alberta Hailstorms
(American Meteorological Society, 1973)Samples of rain and small hail have been analyzed for their silver content. The samples were collected during both seeded and unseeded storms in the project area of the 1968 Alberta Hail Studies Program. The natural ... -
On the Freezing of Liquid Water in a Cloud
(American Meteorological Society, 1973)A technique due to Saunders is used to give quantitative information on the amount of heating to be realized from the freezing of liquid water in a cloud. The commonly accepted value of ?C per gram of water frozen per ... -
Cumuli structure at Various Stages of Development
(American Meteorological Society, 1973)The results of simultaneous measurements of thermal structure (convective column temperature and dimensions), of the concentration of droplets of various sizes (diameters from 3?70 ?m), and liquid water content in clouds, ... -
Some Observations of the Microstructure of Dry Cold Fronts
(American Meteorological Society, 1973)The microstructure of dry cold fronts was recorded at a coastal site. Three examples of the fine-structure of temperature and horizontal wind measured at 14 m are discussed. One example includes the refractive index ... -
Equilibrium, Potential and Actual Evaporation from Cropped Surfaces in Southern Ontario
(American Meteorological Society, 1973)Micrometeorological data collected over cropped surfaces at Simcoe in southern Ontario are used to evaluate various evaporation rates. Data collected in 1971 from two plots of perennial ryegrass, one of which was irrigated, ... -
Daily Spatial and Secular Variations of Atmospheric Humidity in a Small City
(American Meteorological Society, 1973)An investigation of the effects of Chapel Hill, N.C., and its suburbs on the temporal and spatial patterns of dew point temperature was conducted in the early fall months of 1971. Six 55-mi traverses over city and non-city ... -
Three Aspects of the Urban Climate of Detroit-Windsor
(American Meteorological Society, 1973)In the present study, a beginning is made into the investigation of the effect of the urban area on the microclimate of Detroit-Windsor. Diurnal and seasonal urban-rural temperature differences were investigated using ...
