An Audio-Modulated Tethersonde for Detailed Micrometeorological Soundings
(American Meteorological Society, 1967)A tethered sonde for obtaining detailed micrometeorological soundings in the lower 500 m of the atmosphere is described. The instrument was developed to be directly compatible with the current audio-modulated radiosonde ... -
Direct Measurement of Vapor Pressure Fluctuations and Gradients
(American Meteorological Society, 1967)An instrument for direct measurement of vapor pressure and vapor pressure gradient (and similarly for temperature) has been designed and constructed. Thermistors are used as wet-and dry-bulb thermometers in the adjacent ... -
A Sensitive Cup-Type Anemometer
(American Meteorological Society, 1967)A sensitive cup-type anemometer was developed which is mechanically and electrically simple. The characteristics include a starting speed of 6 cm sec?1, distance constant (63%) of 90 cm, and a linear response. -
An Integrating Pyranometer for Climatological Observer Stations and Mesoscale Networks
(American Meteorological Society, 1967)The silicon photovoltaic solar cell has made possible the construction of simple pyranometers of reasonable accuracy. Cell response is linear, temperature sensitivity is low, and spectral response does not cause serious ... -
An Estimation of the Effects of Precipitation on Scheduling of Extended Outdoor Activities
(American Meteorological Society, 1967)A simulation model using Monte Carlo techniques based on Markov chain probabilities of ppreciitation is proposed as a means to determine the number of workdays available in a given calendar period, or the number of calendar ... -
Infrared Limb Darkening of the Earth from Statistical Analysis of TIROS Data
(American Meteorological Society, 1967)The infrared radiance data obtained from measurements by the TIROS satellites have been used to deduce the limb darkening. Large numbers of data permit a statistical treatment in a matrix of radiance and local zenith angle. ... -
Mountain Lee Waves in the Middle East: Theoretical Calculations Compared with Satellite Pictures
(American Meteorological Society, 1967)Four cases of mountain lee waves in the Middle East are discussed. The wavelengths as observed on satellite pictures are compared with calculations of wavelengths based on several different assumptions. Results show that ... -
Estimation of Radio Ray Attenuation in Convective Rainfalls
(American Meteorological Society, 1967)A model is developed for use in estimating rainfall attenuation at frequencies above 3 GHz in showers and other types of sporadic rainfall, usually associated with atmospheric convective activity. The model assumes a ... -
A Field Technique for Detecting Silver Iodide in Snow
(American Meteorological Society, 1967)A field technique was developed to detect silver iodide seeding agent in snow samples. The technique consists of collecting snow during a snow storm, forming liquid drops by melting pellets made from the snow, and refreezing ... -
Evaporation from a Wet Soil Surface Calculated from Radiometrically Determined Surface Temperatures
(American Meteorological Society, 1967)The temperature of a naturally exposed, bare wet soil surface was measured with a narrow bandpass infrared radiation thermometer. Corrections were made for actual sky radiance and for surface emittance, the latter also ... -
The Rise of Strongly Radioactive Plumes
(American Meteorological Society, 1967)The presence of radioactive gases in a plume, such as could occur in the event of a nuclear reactor accident, leads to the addition of buoyancy to the plume at an approximately linear rate. Buoyancy might also be added to ... -
Empirical Dependence of the Eddy Coefficient for Heat upon Stability Above the Lowest 50 m
(American Meteorological Society, 1967)A rather general formulation is utilized for the stability dependence of the eddy coefficient for heat KH above the lowest 50 m. It contains five empirical parameters which pertain to the magnitude of KH in neutral conditions, ... -
On the Further Development of Gringorten's Stochastic Model for Climatological Predictions
(American Meteorological Society, 1967)A statistical model based on a Monte Carlo simulation technique has been proposed by Gringorten for making estimates of the duration and frequency of weather events. The model was evaluated and its predictive results tested. ... -
Significance Tests of the Differences Between Movements of Typhoons and Tropical Storms
(American Meteorological Society, 1967)Nineteen years of northwest Pacific tropical cyclone movements are stratified for studying the relation between storm intensity and subsequent movement. The t-test was applied to determine whether the differences between ... -
Mesoscale Wave Motions as Revealed by Improved Wind Profile Measurements
(American Meteorological Society, 1967)The mesoscale structure of atmospheric winds between the surface and 20 km is analyzed using data obtained from the FPS-16 radar/Jimsphere precision wind measuring system. The accuracy and resolution of these data are far ... -
The Effect of Analysis Errors on Some Predictions Made with the Spectral Vorticity Equation
(American Meteorological Society, 1967)A theoretical method of determining minimum variances was applied to predictions made with the barotropic vorticity equation written in spectral form. The theory was first tested on hypothetical data, and then three synoptic ... -
The Statistical Objective Analysis of Scalar Data Fields
(American Meteorological Society, 1967)Most current objective analysis schemes require a rather subjective pre-specification of ?weight curves? in their interpolation formulae. This has the effect of preordaining, to a certain extent, the manner in which the ... -
