The Effect of Vapor Depletion on Ice Nucleus Measurements with Membrane Filters
(American Meteorological Society, 1973)The depletion of water vapor during humidification of filter samples, which introduces complications in the determination of ice nucleus concentrations, is considered in detail. A complete solution of the problem appears ... -
Cloud Chamber Tests of Generators Using Acetone Solutions of AgI-NaI, AgI-KI and AgI-NH4I
(American Meteorological Society, 1973)The ice-nucleating properties of cloud seeding materials produced by burning acetone solutions of AgI-NaI, AgI-KI and AgI-NH4I have been tested in a wind-tunnel cloud-chamber test facility. The AgI aerosol produced from ... -
Evaluation of NCAR Ice Nucleus Counter. Part I: Basic Operation
(American Meteorological Society, 1973)A detailed examination was made of the variables affecting the operation of the National Center for Atmospheric Research (NCAR) ice nucleus counter. The design criteria for proper flow control to achieve consistent cloud ... -
Analysis of Results from Second International Ice Nucleus Workshop with Emphasis on Expansion Chambers, NCAR Counters, and Membrane Filters
(American Meteorological Society, 1973)The Second International Workshop on Condensation and Ice Nuclei, held at Ft. Collins, Colo., in 1970, provided approximately 10,000 measurements by ice nucleus counters of natural and artificial aerosols, with the counters ... -
Experimental Investigation of Transient Supersaturations in a Thermal Diffusion Chamber
(American Meteorological Society, 1973)The effect of transient supersaturations on the concentration of cloud condensation nuclei (CCN) in a conventional parallel-plate type thermal diffusion chamber is experimentally investigated by controlling the relative ... -
On a Study of Winter Season Wind Structure at 500 mb in the Indian Region for Use in Objective Analysis of the Wind Field
(American Meteorological Society, 1973)The statistical macrostructure of the wind field at 500 mb in the Indian region has been studied for the purpose of deriving useful information regarding scan length, scan area and weighting function for Cressman's method ... -
Analysis of Hurricane Data Using the Variational Optimization Approach with a Dynamic Constraint
(American Meteorological Society, 1973)The variational optimization technique is used to develop analysis equations for the high-energy portion of the hurricane. The specified functional contains an observational constraint, two low-pass filter terms, and a ... -
Heat Balance Investigation in an Arctic Mountainous Area in Northern Alaska
(American Meteorological Society, 1973)Short-term heat balance studies were carried out for three surfaces?moraine, ice and snow?in a partly glacierized watershed in Arctic Alaska, for an 11-day period in summer 1971. It was found that the radiation balances ... -
A Numerical Model of the Effects of Seeding on the Evolution of a Lake-Effect Storm
(American Meteorological Society, 1973)The simulation of crystal growth by diffusion and by accretion of cloud droplets is incorporated into the Lavoie mesoscale numerical model for lake-effect storms. The model also allows simulation of seeding and its effect ... -
Crop-Weather Analysis Model: Review and Model Development
(American Meteorological Society, 1973)This paper presents a brief review of selected literature pertaining to crop-weather analysis and the development of a new climatological technique which evaluates the simple and interacting daily contributions of up to ... -
Urban Influence on a Strong Daytime Air Flow as Determined from Tetroon Flights
(American Meteorological Society, 1973)Tetroon flights across Oklahoma City indicate the influence of an isolated urban area on the horizontal and vertical air velocity at heights near 400 m in relatively strong (13 m sec?1) daytime flow. The Lagrangian ... -
Acquisition and Characterization of Surface Material Data for Urban Climatological Studies
(American Meteorological Society, 1973)A sampling and analysis scheme is presented and briefly illustrated for examination of the type, amount and degree of areas contiguity among surface materials in urban areas. Such data are necessary if we are to understand ... -
Modeling of the Effects of Gaseous and Particulate Pollutants in the Urban Atmosphere. Part II: Pollutant Dispersion
(American Meteorological Society, 1973)In conjunction with a companion study, this paper discusses the pollutant dispersion as predicted by solving numerically the equations of a transient, one-dimensional transport model. The results show that while the radiative ... -
Modeling of the Effects of Gaseous and Particulate Pollutants in the Urban Atmosphere. Part I: Thermal Structure
(American Meteorological Society, 1973)The short-term effect of radiatively participating pollutants upon the temperature distribution in the boundary layer of the urban atmosphere is predicted. This is accomplished by constructing a mathematical model for ... -

A Relationship Between Stratification, Cloud Depth, and Permitted Cloud Radii
(American Meteorological Society, 1973)A one-dimensional cumulus model is used to interrelate cloud radius, stratification and cloud height. It is suggested that if only certain ranges of cloud height and radius are permitted, then from the stratification, one ... -
