Variability in Estimating Total Cloud Cover from Satellite Pictures
(American Meteorological Society, 1967)Ten qualified weather observers were used to make estimates of the total cloud cover from satellite pictures. Tests were conducted to determine the standard deviation of estimates, the significance of the difference in ... -
Relationships Between the Size of Satellite-Observed Cirrus Shields and the Severity of Thunderstorm Complexes
(American Meteorological Society, 1967)Seventeen thunderstorm complexes, observed by TIROS satellite over the United States, were investigated. The diameter of the conspicuously bright storm cloud shield, composed of integrated thunderstorm anvils, has been ... -
Midwinter Stratospheric Warmings in the Southern Hemisphere General Remarks and a Case Study
(American Meteorological Society, 1967)Anomalously high stratospheric temperatures were measured by rocket sounding techniques over McMurdo, Antarctica, in midwinter 1963. Because of the importance of these observations in determining whether the Southern ... -
The Prediction of Clear Air Turbulence over Mountainous Terrain
(American Meteorological Society, 1967)Recent aircraft measurements of clear air turbulence over Australia have shown that the phenomenon of CAT in a thermally stable environment is associated with a breakdown of waves, presumably gravity waves or Helmholtz ... -
Crop-Hail Intensities in Central and Northwest United States
(American Meteorological Society, 1967)Information on hail intensity is not readily available on a national or local scale. As a result, a study was made to obtain general estimates of the mean areal patterns of hail intensity in the central and northwestern ... -
Areal-Temporal Variations of Hail Intensity in Illinois
(American Meteorological Society, 1967)Four forms of hail data in Illinois were analyzed to obtain indirect measures of the areal and seasonal variations in hail intensity. These data were also examined to ascertain which hail characteristics correlated best ... -
Low-Altitude Input of Artificial Radioactivity to a Severe Convective Storm—Comparison with Deposition
(American Meteorological Society, 1967)Concentrations of artificial radioactivity and plant pollens in rain have been found to vary in phase during convective storms. Because pollens are tracers for low-altitude air, this result is most simply explained by ... -
Mathematical and Synoptic Aspects of a Small-Scale Wave Disturbance Over the Lower Great Lakes Area
(American Meteorological Society, 1967)A squall line which crossed the lower Great Lakes area on 13 March 1963 is described. Characteristics of the squall line are compared to typical features of such phenomena deduced in other studies. The instability line was ... -
A Stable Finite Difference Scheme for the Linearized Vorticity and Divergence Equation System
(American Meteorological Society, 1967)A modification of Saul'ev's finite difference scheme for the heat equation is applied to the vorticity and divergence equation system for a rotating barotropic fluid. The scheme entails the use of two time levels to ... -
Surface Wind Sampling for Unguided Rocket Impact Prediction
(American Meteorological Society, 1967)This report presents results of studies performed at White Sands Missile Range, N. Mex., to determine the optimum data sampling period for obtaining representative (average) surface winds for use in prelaunch real-time ... -
Application of the Lidar to Air Pollution Measurements
(American Meteorological Society, 1967)An urgent need exists for a technique of rapid and economical measurement of vertical profiles of atmospheric particulate concentration. It is shown in this paper that the lidar, or optical radar, is capable of meeting ... -
The Effect of Meteorological Factors on Air Pollution in a Narrow Valley
(American Meteorological Society, 1967)The Air Pollution Division of the State of Pennsylvania has conducted simultaneous measurements of meteorological variables and air quality at Johnstown, Pa. An analysis of the observations for two fall seasons showed that ... -
A Water-Level Measuring System for Determining Evapotranspiration Rates from a Floating Lysimeter
(American Meteorological Society, 1967)The water level in a sump of a 6.1 m diameter floating lysimeter tank is measured by a linear-variable differential transformer. The transducer output representing weight changes of the floating tank is recorded continuously ... -
Pan Evaporation, Potential and Actual Evapotranspiration
(American Meteorological Society, 1967)A formula for estimating the evapotranspiration rate from temperature and relative humidity data is given. Results of some tests of the accuracy of the equation indicate that it is better than other equations based on a ...
