Real-Time Image Enhancement of Meteorological and Maritime Processes
(American Meteorological Society, 1974)The spatial and spectral luminance properties of a cloud's surface are being studied to gather more information about the microphysical processes occurring within the cloud. A real-time, field-implementable image processing ... -
Multiple Contrail Streamers Observed by Radar
(American Meteorological Society, 1974)An unusual case of multiple streamers or filaments with the characteristic mare's tail pattern in vertical section has been observed by radar where the generating elements were condensation trails laid by high-altitude ... -
Experimental Studies of Modified R-Meter Theory
(American Meteorological Society, 1974)The validity of the extension of R-meter theory advanced by W. H. Lob has been tested experimentally by laboratory simulation of both radar signals and typical radar signal processing equipment. The experimental results ... -
Measurements of Cloud Condensation Nuclei and Cloud Droplet Size Distributions in the Vicinity of Forest Fires
(American Meteorological Society, 1974)Airborne measurements of cloud condensation nuclei (CCN) were made in the vicinity of a planned burn of natural forest products. The concentrations of CCN, active at 0.5% supersaturation, reached a peak value of 5000 cm?3 ... -
Particle Emissions From a Large Kraft Paper Mill and Their Effects on the Microstructure of Warm Clouds
(American Meteorological Society, 1974)Airborne measurements of cloud condensation nuclei (CCN), total particle counts, the size distribution of particles, and the microstructure of warm clouds have been made in the vicinity of a large Kraft pulp and paper mill. ... -
The Radiative Effect of Aerosols in the Earth's Atmosphere
(American Meteorological Society, 1974)A modified two-flux approximation is employed to compute the transfer of radiation in a finite, inhomogeneous, turbid atmosphere. A perturbation technique is developed to allow the treatment of non-gray gaseous absorption ... -
Corrigendum
(American Meteorological Society, 1974)Correction to Volume 12, Issue 2, page 275. and Correction to Volume 12, Issue 6, page 1018. -

An Observational Study of Convergence and Rainfall over South Florida
(American Meteorological Society, 1974)Relationships between convergence and rainfall at subsynoptic scales of motion are studied observationally. Data are based on special surface wind and rainfall observations in the South Florida peninsula during the period ... -
Evaluation Standards for Dynamical Prediction Models

On the Behavior of Superpressure Balloons at 150 mb
(American Meteorological Society, 1974)This paper presents measured data related to the question of how constant are ?constant-level? balloons. The simultaneous use of two balloon-borne instruments, a radio altimeter and a pressure sensor, operating on entirely ... -
Stratospheric Mixing Estimated from High-Altitude Turbulence Measurements
(American Meteorological Society, 1974)Vertical diffusion coefficients in the stratosphere are estimated from data obtained in the High Altitude Clear Air Turbulence (HICAT) investigation. The HICAT data sample was obtained from 285 flights of over 800,000 km ... -
A Comparison of the Turbulent Fluctuations in Clear Air Convection Measured Simultaneously by Aircraft and Doppler Radar
(American Meteorological Society, 1974)A comparison between the fluctuations in the horizontal component of velocity measured simultaneously by Doppler radar and aircraft has been made in clear air convective conditions. This experiment is the first in which ... -
Effect of Finite Radar Pulse Volume on Turbulence Measurements
(American Meteorological Society, 1974)Equations relating the mean of the Doppler spectrum and the distribution of point velocities, and their spectra are derived under the assumptions that: 1) the scatterers follow the air motion faithfully, 2) the reflectivity ... -
Complex Index of Refraction of Airborne Soil Particles
(American Meteorological Society, 1974)The angular variation of the intensity of light scattered from a collimated beam by airborne soil particles and the size distribution of the particles were measured simultaneously 1.5 m above the ground. These measurements ... -
An Airflow Case Study Over the San Juan Mountains of Colorado
(American Meteorological Society, 1974)On 12 February 1973 an airflow case study was documented across the San Juan Mountains in south-west Colorado. The main observation system was an NCAR Queen Air aircraft. Several supplementary observations were available ... -
The Life Cycle of the Dryline
(American Meteorological Society, 1974)The dryline, a narrow non-frontal zone of sharp moisture discontinuity, has long been known as a preferential location of thunderstorm development. Through an examination of several years of data, a conceptual model of the ... -
The Rise of Moist, Buoyant Plumes
(American Meteorological Society, 1974)The governing equations for a moist, buoyant plume in a cross wind are presented. A comparison of the energy equations for saturated and unsaturated plumes, the subject of some previous controversy, shows that the form of ...
