Fog Modification with Giant Hygroscopic Nuclei
(American Meteorological Society, 1968)Analytic and experimental investigations were conducted to examine the concept of modifying fog with hygroscopic material. An approximate equation was derived that is useful in estimating the feasibility of such applied ... -
On Precipitation Mechanisms and their Artificial Modification
(American Meteorological Society, 1968)Natural precipitation processes are re-examined on the basis of accumulated knowledge of the microphysical aspects and field observations, with particular attention to the implications for cloud seeding. It appears that ... -
An Evaluation of Eddy Flux Variation in the Atmospheric Boundary Layer
(American Meteorological Society, 1968)An evaluation is made of the typical variation with height and time of mean and eddy flow of momentum in the atmospheric boundary layer using carefully determined wind profile data obtained over a separation of 200 m in a ... -
Characteristics of Turbulence Observed at the NASA 150-m Meteorological Tower
(American Meteorological Society, 1968)Recent observations of turbulence obtained at the NASA 150-m meteorological tower located at Kennedy Space Center, Fla., are presented. The wind data were obtained at the 18-, 30-, 60-, 90-, 120- and 150-m levels, while ... -
Deriving Power Spectra from a Three-Component Sonic Anemometer
(American Meteorological Society, 1968)The paper describes the general characteristics of a non-orthogonal sonic anemometer array. The effects of line-averaging and spatial separation (between mid-points of the horizontal paths) are analyzed and spatial transfer ... -
Infrared Measurements of Jet-Stream Cirrus
(American Meteorological Society, 1968)An experimental investigation into the radiative characteristics of jet-stream cirrus was undertaken by using AFCRL's research instrumented U-2 aircraft. Radiation measurements in the 8?13 ? window region along with aerial ... -
Aerial Measurement of Radiation Temperatures over Mt. Fuji and Tokyo Areas and Their Application to the Determination of Ground- and Water-Surface Temperatures
(American Meteorological Society, 1968)A Barnes PRT-4 portable radiometer with a spectral response in the 8?14 ? range was used to determine the equivalent blackbody temperature of 1) the slope of Mt. Fuji, 2) Sagami Bay, and 3) the city of Tokyo. A twin-engine ... -
A Method of Calculating the Direct Shortwave Radiation Income of Slopes
(American Meteorological Society, 1968)A formula has been developed whereby variations in the shortwave radiation income on different slopes in any latitude can be easily determined from a knowledge of surface geometry and the sun's declination. This is achieved ... -
Spatial Variation of Net Radiation, Albedo and Surface Temperature of Forests
(American Meteorological Society, 1968)Economical radiometers were placed at 12 locations within an area of about 1 hectare:six over a hardwood forest 10 m in height, two over white pine of 6 m height, two over juniper openings, one over a ledge opening, and ... -
Characteristics of Wind and Turbulence in and above Model Forests
(American Meteorological Society, 1968)A model forest canopy was designed to simulate the meteorological characteristics of typical live forests. Measurements were made of velocity, turbulence, drag, and gaseous plume spread within the simulated canopy. The ... -
Apollo Landmark Sighting: An Application of Computer Simulation to a Problem in Applied Meteorology
(American Meteorological Society, 1968)A Monte Carlo technique simulates the effects of cloudcover on the performance of the Apollo On-board Navigation System. For each of three simulated Apollo missions, the probability of sighting at least a specific number ... -
An Experiment in the Use of Satellite Data in a Numerical Cloud Prediction Program
(American Meteorological Society, 1968)Cloud data derived from TIROS VII photographs over the North Pacific area were used to supplement synoptic surface cloud data in an automated layered-nephanalysis program. During the test period, cloud data from nine TIROS ... -
“Good” Probability Assessors
(American Meteorological Society, 1968)Since a meteorologist's predictions are subjective, a framework for the evaluation of meteorological probability assessors must be consistent with the theory of subjective probability. Such a framework is described in this ... -
An Objective Layer of Maximum Wind Analysis Technique for the Northern Hemisphere
(American Meteorological Society, 1968)An objective layer of maximum-wind (LRMW) analysis technique which is described and evaluated, has two main features: 1) a categorization procedure that sorts wind profiles into nine jet-stream categories, for the derivation ... -
The Treatment of Moisture and Precipitation in Atmospheric Models Integrated by the Spectral Method
(American Meteorological Society, 1968)A brief examination of some recent applications of the spectral method will clearly establish and display the rapid progress accomplished by this technique over the past several years. A discussion of the feasibility of ... -
The Radiative Cooling Calculation for Application to General Circulation Experiments
(American Meteorological Society, 1968)The Atmospheric Radiation Tables (ART) of Elsasser and Culbertson were used to calculate the atmospheric radiation, and the results are compared with those of other methods. The cooling rate calculated from ART agrees well ... -
