A Statistical Analysis of Wind and Temperature Variables Associated with High Altitude Clear Air Turbulence (HICAT)
(American Meteorological Society, 1970)Chi-square and Kolmogorov-Smirnov statistical tests are applied to distributions of wind and temperature variables measured in conjunction with Project HICAT U-2 flights from worldwide locations. A distinction is made ... -
The Design, Construction, and Use of an Ice Crystal Counter for Ice Crystal Cloud Studies by Aircraft
(American Meteorological Society, 1970)An aircraft instrument is described that gives a real-time measurement of the number of ice crystal particles per unit volume in cirriform clouds. Its method of detection is based on the mechanisms of contact electrification, ... -
Electric Properties of Ice Fog Crystals
(American Meteorological Society, 1970)Electric properties of ice fog crystals were studied using uniform and nonuniform electric-fields. It was observed that natural and artificial ice fog crystals had no significant net charge. An upper bound for the net ... -
Distribution of Contaminants in Ice Grown by Accretion
(American Meteorological Society, 1970)Microchemical analysis and x-ray micrographs were performed on thin slices of ice cylinders artificially grown in a tunnel by accretion of supercooled droplets of contaminated water. Characteristic distribution patterns ... -
The Measurement of Tracer Indium in Rain Samples
(American Meteorological Society, 1970)A radiochemical procedure developed to measure precisely nanogram amounts of the indium tracer used in the study of circulations and rain scavenging processes in severe convective storms is described. The tracer indium ... -
Experiments on Droplets in Free Fall I: Terminal Velocity and Wall Effects
(American Meteorological Society, 1970)A system is described for accurately generating droplets of known size in the diameter range 300?500 ?, and measuring their terminal velocity in air. The error in terminal velocity is <0.5%. Measurements were made using ... -
Observations of Ice Crystals in a Cumulus Cloud Seeded by Vertical-Fall Pyrotechnics
(American Meteorological Society, 1970)Two vertical-fall silver iodide pyrotechnics were inserted into a supercooled cumulus cloud near Flagstaff, Ariz. Within a few minutes, a turret was observed to extend over 1.35 km above the cloud top. The temperature ... -
A Raingage Evaluation of the Miami Reflectivity-Rainfall Rate Relation
(American Meteorological Society, 1970)To provide a foundation for other radar studies in the Miami areas, 50 comparisons were made between shower rainfall recorded by raingages and observed with radar to evaluate the reflectivity Z, rainfall rate R relation, ... -
Precipitation Results from a Pyrotechnic Cumulus Seeding Experiment
(American Meteorological Society, 1970)In an attempt to specify the changes in precipitation produced by alteration of cloud dynamics, airborne seeding with silver iodide pyrotechnics was carried out in South Florida during May 1968. Emphasis was placed on ... -
The Transmittance of the Atmosphere for Solar Radiation on Individual Clear Days
(American Meteorological Society, 1970)Calculations of the mean daily transmittance of the atmosphere for solar radiation based on only one independent variable, surface vapor pressure, are demonstrated to be equally as accurate for Phoenix, Ariz., as similar ... -
The Radiation Balance of the Planet Earth from Radiation Measurements of the Satellite Nimbus II
(American Meteorological Society, 1970)The net flux of radiation at the top of the atmosphere and associated quantities (albedo and outgoing longwave radiation) were computed for five successive semimonthly periods from measurements of the radiance of emitted ... -
Phase Velocity and Structure Calculations for Unstable Quasi-Geostrophic Waves in a Simple Baroclinic Westerly Current
(American Meteorological Society, 1970)A simple numerical method is used to calculate the vertical structure and the phase velocity, c = cr + cii, for small, sinusoidal, quasi-geostrophic, unstable perturbations in a baroclinic zonal current which is independent ... -
Alternative Solutions to the Classical Vertical Velocity Problem
(American Meteorological Society, 1970)The kinematic method for determining vertical velocity ? in pressure coordinates is reviewed. Alternative objective procedures are derived for obtaining ?, and an analytical solution to the pressure-differentiated continuity ... -
