Long-Range Transmission of Pollutants Simulated by a Two-Dimensional Pseudospectral Dispersion Model
(American Meteorological Society, 1977)The pseudospectral dispersion model (Christensen and Prahm, 1976) is adapted for simulation of the long-range transmission of sulphur pollutants in the European region, covering an area of about 4000 km ? 4000 km. Regional ... -
Some Properties of Convective Plume and Small Fair-Weather Cumulus Fields as Measured by Acoustic and Lidar Sounders
(American Meteorological Society, 1977)Results of a preliminary experiment are described in which a lidar-acoustic sounder system was used to measure plume and cloud width and depth. These parameters are shown to be lognormally distributed. By applying the ... -
Use of Nonlinear Least Squares in Meteorological Applications
(American Meteorological Society, 1977)This paper derives formulas for the application of nonlinear least squares. The need for doing statistical error analyses before undertaking any system development is pointed and formulas are derived to compute the covariance ... -
An Analysis of Radar Echo Systems for the Upper Midwestern United States
(American Meteorological Society, 1977)An extensive statistical study was made of the properties of radar echo systems in the upper Midwest region of the United States. Mesoscale groupings of echoes with distance scales 10?100 km and time scales 3?10 h instead ... -
Tetrahedral Scan for Tri-Doppler Radar and Other Remote Sensing Applications
(American Meteorological Society, 1977)A method of radar scan is proposed to efficiently acquire scalar velocity components and generate a natural coordinate system which simplifies and minimizes spatial filtering requirements for certain applications. Tetrahedral ... -
An Investigation of the Synoptic Situations Associated with Major Wildland Fires
(American Meteorological Society, 1977)Fifty-two major wildland fires in the eastern half of the United States were analyzed to determine the synoptic situations involved. Three-fourths of the fires were found near surface frontal areas. The vast majority of ... -
Exposure Frequency Distributions from Multiple Instantaneous Cloud Sources
(American Meteorological Society, 1977)The problem analyzed is the release of polluting material into a turbulent atmosphere from a multitude of known sources dispersed in time and space. Each source produces a cloud instantaneously. Mathematical procedures are ... -
A Direct Method for Obtaining Ballistic Densities from Satellite Radiance Observations
(American Meteorological Society, 1977)A nonstatistical method for obtaining ballistic densities directly from satellite radiance observations is derived. The method takes advantage of the fact that both the ballistic density and the satellite radiances depend ... -
On the Integral of the Surface Layer Profile-Gradient Functions
(American Meteorological Society, 1977)New forms of the exact primitives (Nickerson and Smiley, 1975) for the Businger et al. (1971) surface layer gradients are described for the unstable case. In addition to all the theoretical advantages of the Nickerson and ... -
Vertical Motion Sensing by Parachute Dropsonde
(American Meteorological Society, 1977)A vertical motion sensor based upon radiosonde instrumentation is developed for use in measuring disturbances with vertical velocities typically exceeding about 10 cm s?1. The sensor is carried aloft by balloon and released ... -
Comments on “Dynamics of an Urban Temperature Field—A Case Study”
(American Meteorological Society, 1977)tract -
Significance of Vegetation in Interpreting Thermal Radiation from a Terrestrial Surface
(American Meteorological Society, 1977)The regions between crop rows are modeled as infinitely long diffuse cavities. Geometrical view factors are calculated, accounting for reflected radiation emanating internal to the cavity and from the background sky. A ... -
Verification of Some Numerical Models for Operationally Predicting Mesoscale Winds Aloft
(American Meteorological Society, 1977)Four numerical models are described for predicting mesoscale winds aloft for a 6 h period. These models are all tested statistically against persistence as the control forecast and against predictions made by operational ... -
Comparison of the Vertical Motions of Paired Tetroon Flights
(American Meteorological Society, 1977)Pairs of constant volume balloons (tetroons) released ?1 min apart from the same site at Haswell, Colo., and continuously tracked by two M-33 radars, are used to estimate the mutual consistency of tetroon vertical motions. ... -

Wind Estimates from Cloud Motions: Results from Phases I, II and II of an In Situ Aircraft Verification Experiment
(American Meteorological Society, 1977)An experiment is in progress to verify geostationary satellite derived cloud motion wind estimates by in situ aircraft wind velocity measurements. One or more low-level aircraft equipped with Inertial Navigation Systems ... -
Synoptic-Scale Studies Using the Nimbus 6 Scanning Microwave Spectrometer
(American Meteorological Society, 1977)Several frontal systems over Europe in August 1975 and January and February 1976 are examined using scanning microwave spectrometer (SCAMS) data. Comparisons are made with thermal fields constructed from radiosonde ... -
Problems in the Use of Interference Filters for Spectrophotometric Determination of Total Ozone
(American Meteorological Society, 1977)An analysis of the use of ultraviolet narrow-band interference filters for total ozone determination is given with reference to the New Zealand filter spectrophotometer under the headings of filter monochromaticity, ... -
A Case Study of Stratospheric Ozone Affecting Ground-Level Oxidant Concentrations
(American Meteorological Society, 1977)During the predawn hours of 19 November 1972, the air pollution monitoring station at Santa Rosa, Calif., recorded five consecutive hours of oxidant concentrations in excess of the present National Ambient Air Quality ... -
The Effect of Bandwidth on Filter Instrument Total Ozone Accuracy
(American Meteorological Society, 1977)The effect of the width and shape of the New Zealand filter instrument's passbands on measured total ozone accuracy is determined using a numerical model of the spectral measurement process. The model enables the calculation ...
