On the Relationship Between Horizontal Moisture Convergence and Convective Cloud Formation
(American Meteorological Society, 1971)A technique suggested by H.L. Kuo for parameterizing the net effect of the latent heat released by cumulus convection on large-scale flow is evaluated to determine its applicability to regions of convection in middle ... -
Calculation of the Terminal Velocity of Water Drops
(American Meteorological Society, 1971)Three mathematical expressions for the terminal velocity of water drops in still air as a function of equivalent radius are compared with the experimental data of Gunn and Kinzer. Two of them, derived by curve-fitting ... -
Measurements of Precipitation Particles in Warm Cumuli over Southeast Texas
(American Meteorological Society, 1971)Precipitation particles >250 ? were sampled in the upper regions of warm cumuli over southeast Texas using a foil-belt particle sampler. It was found that relatively high concentrations of drops can occur. Concentrations ... -
A Contact Nucleation Model for Seeded Clouds
(American Meteorological Society, 1971)A simple model is developed for clouds seeded with an AgI-acetone generator with the assumption that the AgI particles will behave only as contact nuclei rather than sublimation nuclei. The model was tested against limited ... -
Radiative Properties of Carbonaceous Aerosols
(American Meteorological Society, 1971)The complex index of refraction for various carbonaceous materials is presented for wavelengths from 0.3????20?. An ensemble of spherical carbon dust particles represented by two size distributions typical of urban aerosols ... -
Source Emissions and the Vertically Integrated Mass Flux of Sulfur Dioxide Across the New York City Area
(American Meteorological Society, 1971)Sulfur dioxide concentrations (in ambient air), obtained from helicopter soundings and traverses, together with wind data from pibals, were used in a kinematic box model to determine hourly average three-dimensional fluxes ... -
The Effect of Atmospheric Aerosols on Climate with Special Reference to Temperature near the Earth's Surface
(American Meteorological Society, 1971)A generalized model of the effect of an optically thin atmospheric aerosol on the terrestrial heat budget is proposed, and applied to the problem of estimating the impact of the aerosol on temperatures near the earth's ... -
Some Mesoscale Features of the Initial Fields of Motion and Temperature for a Lake-Induced Winter Disturbance
(American Meteorological Society, 1971)A primitive equation model was utilized to describe the initial fields of atmospheric motion, temperature and humidity for the case of a snow-squall situation over Lake Ontario. Of primary interest in this study is the ... -
An Estimate of the Heat Balance of a Valley and Hill Station in Central Alaska
(American Meteorological Society, 1971)The heat balance was estimated and climatic elements were compared for two stations in the Fairbanks area on a year-round basis, the first study of this kind carried out in the interior of Alaska. Although the stations ... -
Indices of Windchill of Clothed Persons
(American Meteorological Society, 1971)The concept of windchill as a measure of the combined effects of low temperature and wind is reviewed. An analysis is presented of the effect of these variables on a person dressed for cold climates and takes account of ... -
Low-Frequency Periodicities in Panama Rainfall Runoff
(American Meteorological Society, 1971)Power spectra of daily river runoff for the Rio Chagres show strong peaks at one-year and half-year intervals, typical of tropical monsoon conditions. They do not, however, show any significant power to be associated with ... -
Wet Period Precipitation and the Gamma Distribution
(American Meteorological Society, 1971)The gamma probability distribution, with a shape parameter that varies linearly with number of days in a wet period and a scale parameter independent of length of a wet period, is shown to provide an adequate model to ... -
Modelling Conditional Probability
(American Meteorological Society, 1971)Many studies of the joint frequency of the initial and final conditions of weather elements such as cloud cover, visibility, rainfall or temperature attest to the importance of the initial event as a predictor of the later ... -
An Experiment in Probabilistic Weather Forecasting
(American Meteorological Society, 1971)Probabilistic forecasts were given for temperature and precipitation for 2 and 5-day periods. They were evaluated by a scoring rule and the scores were given as feedback to the participants together with the actual outcomes. ... -
On Global Initialization of the Primitive Equations: Part II. The Divergent Component of the Horizontal Wind
(American Meteorological Society, 1971)The problem of obtaining initial values for vertical motion and the divergent component of horizontal velocity is examined for a global primitive equation model. Only diagnostic methods are considered, the emphasis being ... -
A Six-Level Primitive Equation Model Suitable for Extended Operational Prediction in the Southern Hemisphere
(American Meteorological Society, 1971)A description is given of a primitive equation model designed specifically for extended operational prediction in the Southern Hemisphere. The model closely resembles in dynamical and physical aspects the well-known ... -
