A Climatological Study of the Urban Temperature Anomaly in the Lakeshore Environment at Toronto
(American Meteorological Society, 1969)Metropolitan Toronto (population of about 2,160,000 and area of 2282 km2) is on the north shore of Lake Ontario (area of 19,400 km2). The interaction between the daytime urban heat island and the lake circulation is studied ... -
Climatological Assessment of Natural Precipitation Characteristics for Use in Weather Modification
(American Meteorological Society, 1969)A study has been made of the climatological characteristics of storm precipitation on a point and areal basis through the use of two sets of data. One is from a 12-year operation of a dense raingage network on 400 mi2 in ... -
A Global Climatic Model Based on the Energy Balance of the Earth-Atmosphere System
(American Meteorological Society, 1969)A relatively simple numerical model of the energy balance of the earth-atmosphere is set up and applied. The dependent variable is the average annual sea level temperature in 10° latitude belts. This is expressed basically ... -
Utilization of Time-Dependent Data in Running Solution of Initial Value Problems
(American Meteorological Society, 1969)A method is proposed to update forecasts by optimum utilization of meteorological data received from fixed or moving observation stations at regular or irregular intervals. It involves the application of corrections to the ... -
Wind Shear and Reflectivity Gradient Effects on Doppler Radar Spectra: II
(American Meteorological Society, 1969)Other investigators have discussed the effects of wind and reflectivity gradients across the radar beam on Doppler measurements, but have either estimated their magnitude from a simple approximation or set them aside as ... -
Plan Shear Indicator for Real-Time Doppler Radar Identification of Hazardous Storm Winds
(American Meteorological Society, 1969)The Plan Shear Indicator (PSI) is a new mode for display of meteorological Doppler radar information which may prove to be valuable in identification of hazardous winds and turbulence in storms. It provides real-time ... -
Lidar-Observed Haze Layers Associated with Thermal Structure in the Lower Atmosphere
(American Meteorological Society, 1969)Daytime observations of the vertical temperature and humidity structure in the atmosphere below 1 km made with a Cricketsonde rocket system are compared with simultaneous observations from a ruby lidar (laser radar). ... -
Differences in Dobson Spectrophotometer and Filter Ozonometer Measurements of Total Ozone
(American Meteorological Society, 1969)This paper reviews the results of the first systematic parallel measurements with a Dobson-type spectrophotometer and an M-83 filter ozonometer. Measurements were performed at the University of Sofia during a period of one ... -
The Statistical Prediction of the Vertical Ozone Distribution
(American Meteorological Society, 1969)Total ozone amounts and spectral measurements of backscattered ultraviolet radiation received by a satellite are used as statistical predictors of the vertical ozone distribution at Boulder, Colo. The distribution is ... -
Trace Constituents in the Vicinity of Jet Streams
(American Meteorological Society, 1969)An extensive series of experiments is being undertaken to determine the concentrations and transport of trace atmospheric constituents in the stratosphere and troposphere in the vicinity of jet streams during tropopause ... -
A Study of Aerosols in Pacific Air Masses
(American Meteorological Society, 1969)This paper describes a program of aerosol measurements made in the fall of 1965 at Cape Blanco and Crater Lake, Ore. Aerosol size distributions were determined with a Royco light-scattering type particle counter and with ... -
A Device for Measuring the Radii of Raindrops
(American Meteorological Society, 1969)The sizes of raindrops with radii between 0.025 and 0.2 cm can be measured by amplifying the voltage pulses they make when they hit a high voltage wire. I have made such a device using two wires charged to +2000 V and a ... -
Electrostatic Analysis of Raindrop Distributions
(American Meteorological Society, 1969)The size distribution of raindrops can be determined by a new and simple electrostatic technique. Drops entering the system become electrically charged as they fall through a grid at constant potential V0. When they contact ... -
Sensitive Apparatus For Measurement of Electric Charges on Precipitation
(American Meteorological Society, 1969)An inductor ring device capable of measuring weak electric charges on precipitation was developed. The electronics of the transducer employs a virtual ground configuration for stability in operation and increased sensitivity ... -
Freezing of Water Droplets: Nucleation Efficiency at Temperatures above −5C
(American Meteorological Society, 1969)Numerical values obtained in laboratory studies of nucleation effectiveness of pyrotechnically produced smokes are strongly dependent on experimental conditions. Contact nucleation is shown to be relatively important at ... -
Silver Analysis of Seeded Snow by Atomic Absorption Spectrophotometry
(American Meteorological Society, 1969)An experimental weather modification program using silver iodide as the cloud seeding agent is being conducted over the Park Range in northwestern Colorado. The measure of silver content in target area precipitation can ... -
