Averaging for Wind Speed in a Given Direction in the Concentration Equation for Pollutants
(American Meteorological Society, 1977)In the equation for the concentration of pollutants from a steady continuous point source, in a stationaryturbulent flow, the factor 1/u enters (u is the mean wind for a given stationary situation). If we are interestedin ... -
A Preliminary Analysis of Ocean-Air Interactions Along the West Coast of North America, 1965-1969
(American Meteorological Society, 1977)This paper uses a multivariate statistical technique to examine the possible relationships between theatmosphere and the ocean. Fifteen upper air stations and seventeen water temperature sampling sites werefactor analyzed. ... -
A Comparison of Two CCN Counters
(American Meteorological Society, 1977)A number of careful laboratory comparisons were made between two very different CCN counters. The two instruments gave consistent results which were within about 20% on the average. -

Three-Dimensional Distribution of Air Pollutants in the Los Angeles Basin
(American Meteorological Society, 1977)Data from a three-dimensional pollutant mapping program, conducted in the Los Angeles basin, wereanalyzed to obtain "grand average" vertical profiles sampled on 24 summer days in 1973. Morning andafternoon profiles at four ... -
On the Acceleration of Large Water Drops to Terminal Velocity
(American Meteorological Society, 1977)A theory based on the distortion of large water drops is used to calculate the drag and acceleration ofdrops in the laboratory from rest to terminal velocity. The results show that the drag coefficient curve foreach drop ... -
Laser Absorption Techniques for the Measurementof Atmospheric Water Vapor Concentration
(American Meteorological Society, 1977)A sensitive laser method with fast response time has been developed which is suitable for measuringatmospheric water vapor concentration. The method utilizes the absorption of 33.02 and 27.972 pm radiationfrom a water vapor ... -
A Four-Filter Photometer for the Measurement of Total Ozone in the Atmosphere
(American Meteorological Society, 1977)A description is given of a photometer designed for the measurement of total ozone in the atmosphere fromthe solar light scattered by the zenith sky. The instrument uses four interference filters and a photocell. It ... -
A Narrow Beam Spectral Radiometer to Measure Atmospheric Emission from 4 to 14.5 vm
(American Meteorological Society, 1977)A spectral radiometer to measure atmospheric radiance has been constructed using a helium-cooledphotoconductor detector. The radiometer is of medium resolution (δ?/? ? 2%) and its advantages areits narrow beam ?10-6 sr) ... -
Numerical Computations of the Latitudinal Variation of Solar Radiation for an Atmosphere of Varying Opacity
(American Meteorological Society, 1974)A model for incoming solar radiation is developed for use with readily available meteorological data and is designed for efficiency and accuracy. Purameterizations are used to account for Rayleigh and Mie scattering and ... -
The Design and Use of Sensitive Pressure-Jump Sensors to Detect Thunderstorm Gust Fronts. Part I : Pressure- Jump Detector Design
(American Meteorological Society, 1977)We outline the known properties of atmospheric pressure jumps, including rise-time and pressure-amplitude statistics, and we indicate how these statistics guide the choice of pressure-jump detector components.We review ... -
On the Nature of the Nonexistence of Ordinal Relationships between Measures of the Accuracy and Value of Probability Forecasts : An Example
(American Meteorological Society, 1977)t has been shown previously that ordinal relationships between measures of the accuracy and value ofprobability forecasts do not exist, in general, in N-state (N > 2) situations. Some implications of this resultare illustrated ... -
Real-Time Wind Measurement in Extratropical Cyclones by Means of Doppler Radar
(American Meteorological Society, 1977)Color displays of the velocities of precipitation particles detected with a C-band Doppler radar in wide-spread cyclonic storms provide a variety of real-time information on the atmospheric wind field.Vertical profiles of ... -
Radar-Derived Statistics on the Structure of Precipitation Patterns
(American Meteorological Society, 1977)A large sample of low-elevation weather radar data has been analyzed to give information about the spatialstructure of precipitation patterns. The quantities considered are rainfall rate distributions as a functionof the ... -
Severe Thunderstorm Internal Structure from Dual-Doppler Radar Measurements
(American Meteorological Society, 1977)Dual-Doppler radar data were analyzed for three different times during the life cycle of a severe thunderstorm. The thunderstorm developed a double vortex inside as a tornado was generated beneath the cloud.The organized ... -
A Generalized Urban Air Pollution Model and Its Application to the Study of SO2 Distributions in the St. Louis Metropolitan Area
(American Meteorological Society, 1974)A generalized urban air pollution model, based on numerical integration of the concentration equation, is developed for the study of air pollutant distributions over an urban area. The model computes the temporal and ... -
The Value of Hurricane Forecasts to Oil and Gas Producers in the Gulf of Mexico
(American Meteorological Society, 2004)The threat of hurricanes often forces producers of crude oil and natural gas in the Gulf of Mexico to evacuate offshore drilling rigs and temporarily to cease production. More accurate hurricane forecasts would result in ... -
ECMWF's Global Snow Analysis: Assessment and Revision Based on Satellite Observations
(American Meteorological Society, 2004)Snow water equivalent and snow extent are key parameters for the earth's energy and water budget. In this study, the current operational snow-depth analysis (2D spatial Cressman interpolation) at the European Centre for ... -
An Integrated Approach toward Retrieving Physically Consistent Profiles of Temperature, Humidity, and Cloud Liquid Water
(American Meteorological Society, 2004)A method is presented for deriving physically consistent profiles of temperature, humidity, and cloud liquid water content. This approach combines a ground-based multichannel microwave radiometer, a cloud radar, a ... -
