The High-Latitude Density Regime at Rocket Altitudes Inferred from Observations in Opposite Hemispheres
(American Meteorological Society, 1966)The compatibility of rocket observational results in the Arctic and Antarctic is examined for altitudes in the upper stratosphere. Atmospheric densities are derived from rocket pressure gage and thermistor observations at ... -
Ambient Temperature Measurements from Radiosondes Flown on Constant-Level Balloons
(American Meteorological Society, 1966)A cause of erroneous temperatures obtained in the earlier phases of a study using standard radiosondes flown on constant-level balloons at White Sands Missile Range is discussed. A simple and inexpensive modification of ... -
Progress in Circumventing Limitations of Upper Wind Records
(American Meteorological Society, 1966)Climatological upper wind records have been found to be inadequate for certain statistical analyses such as the computation of interlevel correlation coefficients, time series analysis and persistence analysis. This article ... -
Upper Air Sounding Analysis by Use of an Electronic Computer
(American Meteorological Society, 1966)The upper air sounding analysis technique currently employed by the Severe Local Storms Forecasting Unit of the U.S. Weather Bureau at Kansas City has been programmed for computation by an electronic computer. Equations ... -
Performance Measurements of Silver-Iodide Smoke Generators on Aircraft
(American Meteorological Society, 1966)The performance of a silver iodide smoke generator, mounted on an aircraft, was measured in flight. The ice-nucleus output was 1014 per gram of silver iodide active at ?15C and 1012 at ?10C. Considerable variations in the ... -
Generation of Metaldehyde Smoke
(American Meteorological Society, 1966)A technique has been developed for generating fine particles of metaldehyde for possible use in nucleating ice in supercooled clouds. The number of particles effective as ice nuclei is 1012 gm?1 at ?12C and 6?109 gm?1 at ... -
Low-level Jet at White Sands Missile Range
(American Meteorological Society, 1966)Wind data collected at White Sands Missile Range, New Mexico, frequently show a sharp maximum in the wind speed profile below 3000 ft. This low-level maximum is often supergeostrophic and associated with large values of ... -
Climatic Visibilities of the United States
(American Meteorological Society, 1966)Climatological visibility data for fifty-three sites is used to evolve seasonal visibility maps of the United States. The analysis is presented in the form of cumulative visibility frequency distribution maps. A brief ... -
Expansion of Hemispheric Meteorological Data in Antisymmetric Surface Spherical Harmonic (Laplace) Series
(American Meteorological Society, 1966)A brief review of methods of expanding scalar functions in surface spherical harmonic or Laplace series reveals that the method proposed by Neumann in 1838 has distinct advantages. Since it allows exploitation of the ... -
Evaluation of Spectral Versus Grid Methods of Hemispheric Numerical Weather Prediction
(American Meteorological Society, 1966)Using observed hemispheric meteorological data as initial conditions, typical barotropic (one-level) filtered-equation numerical weather prediction models were integrated both by the conventional grid-point method and by ... -
Objective Cross Section Analysis
(American Meteorological Society, 1966)The distribution of wind and of temperature in a vertical cross section through the atmosphere is derived from radiosonde and rawinsonde data by an objective analysis procedure suitable for automatic computers. The method ... -

The Laboratory and Field Evaluation of Weathercord, a High Output Cloud Seeding Device
(American Meteorological Society, 1966)Weathereord, a 40-grain detonating fuse containing about 20 per cent of silver iodide, has been evaluated as a cloud seeding nuclei generator in the laboratory, in the field, and in aircraft cloud seeding. Comparative data ... -
An Aircraft Impactor for Determining the Size Distributions of Tropospheric Aerosols
(American Meteorological Society, 1966)The design and development of an aircraft-borne isokinetic sampling device for collecting, tropospheric aerosol particles is described. The device incorporates a two-stage impactor and a back-up filter for collection and ...
