Variability of Wind with Distance and Time on an Isobaric Surface
(American Meteorological Society, 1972)Maps of the contours for the two-point wind correlation coefficient for zonal and meridional components over North America are shown for time lags of ?3, ?2, ?1, 0, +1, +2, +3 days at the 500-mb level, winter. The applications ... -
Instrument Requirements for Eddy Correlation Measurements
(American Meteorological Society, 1972)The response requirements of the sensors, in particular the vertical wind sensor, used for eddy correlation measurements are discussed. Data are presented to allow estimation of the errors due to inadequate cosine and ... -
Analysis of Meteorological Data by Means of Canonical Decomposition and Biplots
(American Meteorological Society, 1972)The biplot is a graphical display of a two-dimensional approximation to a matrix. Its usefulness in the display and analysis of matrices of meteorological data is demonstrated by a detailed exposition of two illustrations ... -
A Simple Model for Determining Evaporation from High-Latitude Upland Sites
(American Meteorological Society, 1972)Energy-budget calculations and equilibrium, model estimates of evaporation from a lichen-dominated upland site in the Hudson Bay lowlands are presented. The energy-budget calculations reveal that the lichen surface is ... -
The Local Surface Energy Balance and Subsurface Temperature Regime in Antarctica
(American Meteorological Society, 1972)The physical processes occurring within a perennial snow cover and at its surface are discussed with particular emphasis on monthly variations in Antarctic snow. Results of a one-year simulation of physical processes In ... -
Some Aspects of Denver Air Pollution Meteorology
(American Meteorological Society, 1972)First, the atmospheric transport equations for citywide particulate air pollution are stated and methods for the numerical evaluation of each term are discussed. Next, the role of the several transport mechanisms in producing ... -
Applications of a Numerical Air Pollution Transport Model to Dispersion in the Atmospheric Boundary Layer
(American Meteorological Society, 1972)A numerical, advection-diffusion air pollution transport model is used to describe dispersion of emissions from urban area-type sources for several atmospheric stability situations, The estimation of appropriate velocity ... -

Bistatic Radar Detection of the Melting Layer
(American Meteorological Society, 1972)Recent operation of the Valley Forge-Wallops Island bistatic radar link during two days characterized by light rain and drizzle provided some detailed, bistatically derived information on atmospheric structure in the ... -
A Giant Hailstone from Kansas in Free Fall
(American Meteorological Society, 1972)Replicas of a hailstone that weighed 766 gm and which had large spikes confined mainly to one side were dropped from heights of up to 900 m and also tested in a wind tunnel to determine the hailstone's aerodynamic properties. ... -
Observed Doppler Spectra of Hail
(American Meteorological Society, 1972)Observations of Doppler spectra from particles 610 m above the ground were obtained by means of a vertically pointing X-band radar during a period when large hail was falling at the ground. It was found that the variance ... -
Height and Temperature of First Echoes in Unseeded and Seeded Convective Clouds in South Dakota
(American Meteorological Society, 1972)The height and temperature of first radar echoes observed on 49 test cases in a randomized cloud seeding project have been related to seeding treatment and to five cloud parameters, namely, cloud base height, cloud base ... -
High-Temperature Contact Nucleation of Supercooled Water by Organic Chemicals
(American Meteorological Society, 1972)A simple, rapid test is described that measures contact nucleation of supercooled water. Application of this contact-nucleation test at ?3C to over 1000 organic compounds resulted in only 47 that could be considered as ... -
Measurements of Aerosol Size Distributions and Vertical Fluxes of Aerosols on Land Subject to Wind Erosion
(American Meteorological Society, 1972)To assess wind erosion as a source of atmospheric soil particles, vertical aerosol fluxes near the ground in an eroding field were computed by assuming a vertical transport mechanism similar to that for momentum. Aerosol ... -
A Study of the Relationship of Chemical Composition and Humidity to Light Scattering by Aerosols
(American Meteorological Society, 1972)A chemically pure aerosol of defined size distribution exhibits a unique growth pattern due to adsorption of water vapor, and to hygroscopic and/or deliquescence effects which are dependent upon relative humidity and which ... -
Ground-Based Sensing of Temperature Profiles from Angular and Multi-Spectral Microwave Emission Measurements
(American Meteorological Society, 1972)The use of angular-scan and multi-spectral techniques for Inferring temperature profiles from ground-based radiometric observations of emission by atmospheric oxygen is discussed. A recently developed multi-frequency ... -
Numerical Modeling of Carbon Monoxide Concentrations Near Highways
(American Meteorological Society, 1972)Numerical models have been designed to compute carbon monoxide concentrations in the vicinity of a plane highway and a depressed highway in Toronto. The non-steady two-dimensional diffusion equation is integrated in time ...
